Biotechnology in Plant Protection and Crop Improvement. [54] Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its Flavr Savr delayed ripening tomato. Improvements in nutritional value for forage crops from the use of analytical chemistry and rumen fermentation technology have been recorded since 1960; this science and technology gave breeders the ability to screen thousands of samples within a small amount of time, meaning breeders could identify a high performing hybrid quicker. doi:10.3109/07388551.2015.1130684. [21] Most notably, organic farmers have fewer inputs available than conventional growers to control their production environments. The presented articles suggesting possible harm of GMOs received high public attention. We emphasize that with over 1783 published articles on GMOs over the last 10 years it is expected that some of them should have reported undesired differences between GMOs and conventional crops even if no such differences exist in reality. [citation needed]. Here, we show that a number of articles some of which have strongly and negatively influenced the public opinion on GM crops and even provoked political actions, such as GMO embargo, share common flaws in the statistical evaluation of the data. doi:10.1177/0162243915598381. [14][15] Biosensor MOSFETs were later developed, and they have since been widely used to measure physical, chemical, biological and environmental parameters.

Tissue Culture 6. Critical Reviews in Biotechnology. Modern plant breeding may use techniques of molecular biology to select, or in the case of genetic modification, to insert, desirable traits into plants. CMS is a maternally inherited trait that makes the plant produce sterile pollen. These techniques have allowed for the introduction of new crop traits as well as a far greater control over a food's genetic structure than previously afforded by methods such as selective breeding and mutation breeding. BMC Proceedings, 31–35. [78] However, opponents have objected to GM crops per se on several grounds, including environmental concerns, whether food produced from GM crops is safe, whether GM crops are needed to address the world's food needs, and economic concerns raised by the fact these organisms are subject to intellectual property law. "[41], Examples in food crops include resistance to certain pests,[42] diseases,[43] stressful environmental conditions,[44] resistance to chemical treatments (e.g. Modern plant breeding is applied genetics, but its scientific basis is broader, covering molecular biology, cytology, systematics, physiology, pathology, entomology, chemistry, and statistics (biometrics). [1] Per the European Federation of Biotechnology, biotechnology is the integration of natural science and organisms, cells, parts thereof, and molecular analogues for products and services. The study, conducted at the Biochemical Institute, University of Texas at Austin, concluded in summary: "We suggest that any real declines are generally most easily explained by changes in cultivated varieties between 1950 and 1999, in which there may be trade-offs between yield and nutrient content."[16]. When distantly related species are crossed, plant breeders make use of a number of plant tissue culture techniques to produce progeny from otherwise fruitless mating. Some medical organizations, including the, Regulation of the release of genetic modified organisms, National Institute of General Medical Sciences, Key Biotechnology Indicators (December 2011), Biotechnology policies – Organization for Economic Co-operation and Development, "History, scope and development of biotechnology", Diamond v. Chakrabarty, 447 U.S. 303 (1980). Wheat hybrids were bred to increase the crop production of Italy during the so-called "Battle for Grain" (1925–1940). PMID 26767435. Using this method decreases the need for breeding multiple generations of plants to get a generation that is homogenous for the desired traits, thereby saving much time over the natural version of the same process. 4. Chemical mutagens like EMS and DMS, radiation and transposons are used to generate mutants with desirable traits to be bred with other cultivars – a process known as Mutation Breeding. [23], With an increasing population, the production of food needs to increase with it. (2004). [3] Pharmacogenomics (a combination of pharmacology and genomics) is the technology that analyses how genetic makeup affects an individual's response to drugs. Biotechnology uses several scientific tools and techniques in agriculture in order to imrove the productivity of crops including mutagenesis, genetic engineering, molecular diagnostics, tissue culture, molecular markers, and vaccines. This is the method used to produce glyphosate resistant ("Roundup Ready") crop plants. [84] The cultivation of GMOs has triggered a debate about coexistence of GM and non GM crops. While only a few GMOs have been approved for cultivation in the EU a number of GMOs have been approved for import and processing. [39][40] Since genetic testing may open up ethical or psychological problems, genetic testing is often accompanied by genetic counseling. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. Genetic testing identifies changes in chromosomes, genes, or proteins. This can be considered as the use of knowledge from working with and manipulating biology to achieve a result that can improve functions in plants and animals. There are many classical and modern breeding techniques that can be utilized for crop improvement in organic agriculture despite the ban on genetically modified organisms. Sometimes genetic modification can produce a plant with the desired trait or traits faster than classical breeding because the majority of the plant's genome is not altered. The detection of the usefulness of heterosis for plant breeding has led to the development of inbred lines that reveal a heterotic yield advantage when they are crossed. Grafting technology had been practiced in China before 2000 BCE. [36][37] Biotechnology has also enabled emerging therapeutics like gene therapy. [53] As of 2011, 11 different transgenic crops were grown commercially on 395 million acres (160 million hectares) in 29 countries such as the US, Brazil, Argentina, India, Canada, China, Paraguay, Pakistan, South Africa, Uruguay, Bolivia, Australia, Philippines, Myanmar, Burkina Faso, Mexico and Spain. Sometimes many different genes can influence a desirable trait in plant breeding. [38] Most of the time, testing is used to find changes that are associated with inherited disorders. [5], By 500 BCE grafting was well established and practiced.[6]. [33] Such approaches promise the advent of "personalized medicine"; in which drugs and drug combinations are optimized for each individual's unique genetic makeup. biodegradable plastics, vegetable oil, biofuels), and environmental uses. The progeny from that cross would then be tested for yield (selection, as described above) and mildew resistance and high-yielding resistant plants would be further developed. (Chakrabarty's work did not involve gene manipulation but rather the transfer of entire organelles between strains of the Pseudomonas bacterium. [8] These processes were introduced in early Mesopotamia, Egypt, China and India, and still use the same basic biological methods. With classical breeding techniques, the breeder does not know exactly what genes have been introduced to the new cultivars. The genetically engineered bacteria are able to produce large quantities of synthetic human insulin at relatively low cost. TCE: The Chemical Engineer, (816), 26–31. It has been projected that global food production must increase by 70% to meet the demand caused by this growing global population, increasing incomes and consumption. Insect resistance is achieved through incorporation of a gene from Bacillus thuringiensis (Bt) that encodes a protein that is toxic to some insects. Universities nationwide compete for these funds to establish Biotechnology Training Programs (BTPs). Quality Protein Maize 117. Crop improvement: Biotechnology is widely used to produce high yielding varieties of crops. Polyploidy 5. [11], [clarification needed]Homozygous plants with desirable traits can be produced from heterozygous starting plants, if a haploid cell with the alleles for those traits can be produced, and then used to make a doubled haploid. Induced polyploidy, and the addition or removal of chromosomes using a technique called chromosome engineering may also be used. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and also to produce biological weapons. Role of Bioinformatics in Crop Improvement . Modern usage also includes genetic engineering as well as cell and tissue culture technologies. When a desirable trait has been bred into a species, a number of crosses to the favored parent are made to make the new plant as similar to the favored parent as possible. If fertilization is possible between two species or genera, the hybrid embryo may abort before maturation. This enables the production of hybrids without the need for labor-intensive detasseling. The wide concept of "biotech" or "biotechnology" encompasses a wide range of procedures for modifying living organisms according to human purposes, going back to domestication of animals, cultivation of the plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. The cells in the plants derived from the first generation created from the cross contained an uneven number of chromosomes and as a result was sterile. Biotechnology is the research and development in the laboratory using bioinformatics for exploration, extraction, exploitation and production from any living organisms and any source of biomass by means of biochemical engineering where high value-added products could be planned (reproduced by biosynthesis, for example), forecasted, formulated, developed, manufactured, and marketed for the purpose of sustainable operations (for the return from bottomless initial investment on R & D) and gaining durable patents rights (for exclusives rights for sales, and prior to this to receive national and international approval from the results on animal experiment and human experiment, especially on the pharmaceutical branch of biotechnology to prevent any undetected side-effects or safety concerns by using the products). [67][68][69] Nonetheless, members of the public are much less likely than scientists to perceive GM foods as safe. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. Electronic Journal of Biotechnology, (3), 01, U.S. Department of State International Information Programs, "Frequently Asked Questions About Biotechnology", USIS Online; available from. Crops need to be able to mature in multiple environments to allow worldwide access, which involves solving problems including drought tolerance. [24][25], Plant breeding can contribute to global food security as it is a cost-effective tool for increasing nutritional value of forage and crops. In the twentieth century plant breeding developed a scientific basis, and crop improvement was understood to be brought about by achieving favorable accumulations and combinations of genes. [47] Examples in non-food crops include production of pharmaceutical agents,[48] biofuels,[49] and other industrially useful goods,[50] as well as for bioremediation. To genetically modify a plant, a genetic construct must be designed so that the gene to be added or removed will be expressed by the plant. By contrast, bioengineering is generally thought of as a related field that more heavily emphasizes higher systems approaches (not necessarily the altering or using of biological materials directly) for interfacing with and utilizing living things. Biotechnology has applications in four major industrial areas, including health care (medical), crop production and agriculture, non-food (industrial) uses of crops and other products (e.g. GM livestock have also been experimentally developed; in November 2013 none were available on the market,[56] but in 2015 the FDA approved the first GM salmon for commercial production and consumption. Biotechnology refers generally to the application of a wide range of scientific techniques to the modification and improvement of plants, animals, and microorganisms that are of economic importance. By using renewable raw materials to produce a variety of chemicals and fuels, industrial biotechnology is actively advancing towards lowering greenhouse gas emissions and moving away from a petrochemical-based economy.[80]. 40 (6): 883–914. Reductions in calcium, phosphorus, iron and ascorbic acid were also found. But what do the different colours of biotechnology have to offer the pharmaceutical industry. In the early 20th century, plant breeders realized that Mendel's findings on the non-random nature of inheritance could be applied to seedling populations produced through deliberate pollinations to predict the frequencies of different types. [79] In the current decades, significant progress has been done in creating genetically modified organisms (GMOs) that enhance the diversity of applications and economical viability of industrial biotechnology. Abs genomic technologies, have led to an explosive growth agricultural by. [13] Two years later, Leland C. Clark and Champ Lyons invented the first biosensor in 1962. 3 Department of Agricultural Economics and Rural Development, ... will play an important role in future crop improvement programs, but other technologies for genomic prediction and selection will also remain important. This process removes most of the genetic contribution of the mildew resistant parent. [15], Modern plant breeding, whether classical or through genetic engineering, comes with issues of concern, particularly with regard to food crops. The plants resulting from adding a gene are often referred to as transgenic plants. In the simplest terms, critics of the increasingly restrictive regulations argue that, through a combination of technical and economic pressures, commercial breeders are reducing biodiversity and significantly constraining individuals (such as farmers) from developing and trading seed on a regional level. [19], By the mid-1980s, other BioFETs had been developed, including the gas sensor FET (GASFET), pressure sensor FET (PRESSFET), chemical field-effect transistor (ChemFET), reference ISFET (REFET), enzyme-modified FET (ENFET) and immunologically modified FET (IMFET). For example, Cauliflower mosaic virus (CaMV) only infects cauliflower and related species. It is estimated that a 70% increase in food production is needed by 2050 in order to meet the Declaration of the World Summit on Food Security. Insulin, widely used for the treatment of diabetes, was previously extracted from the pancreas of abattoir animals (cattle or pigs). [citation needed][clarification needed] All plants have varying sizes and lengths of genomes with genes that code for different proteins, but many are also the same. Biotechnology is a word used to describe the process of using living organisms or any part of these organisms to create new or improved products. Plant Introduction 2. The doubled haploid will be homozygous for the desired traits. Unfortunately, molecular markers are not currently available for many important traits, especially complex ones controlled by many genes. In some instances markers for selection are removed by backcrossing with the parent plant prior to commercial release. Classical breeding is therefore a cyclical process. biotechnology is the term used in crop and livestock improvement through biotechnology tools. [53] 10% of the world's crop lands were planted with GM crops in 2010. Krimsky, Sheldon (2015). Although the process of fermentation was not fully understood until Louis Pasteur's work in 1857, it is still the first use of biotechnology to convert a food source into another form. Isolation is necessary to prevent cross contamination with related plants or the mixing of seeds after harvesting. Another example is using naturally present bacteria by the mining industry in bioleaching. [10], In the early twentieth century scientists gained a greater understanding of microbiology and explored ways of manufacturing specific products. Biotech: true colours. He is engaged in discovering, developing, and delivering innovative R&D solutions to tackle … Decentralized-Participatory Plant Breeding: Adapting Crops to Environments and Clients, Learn how and when to remove this template message, Journal of the American College of Nutrition, ecological impact of genetically modified plants, International Code of Nomenclature for Cultivated Plants, Selection methods in plant breeding based on mode of reproduction, UPOV Convention on New Varieties of Plants, "Precise plant breeding using new genome editing techniques: opportunities, safety and regulation in the EU", "Starch grain and phytolith evidence for early ninth millennium B.P. [11], Biotechnology has also led to the development of antibiotics. To cite one example, in 1978 Genentech developed synthetic humanized insulin by joining its gene with a plasmid vector inserted into the bacterium Escherichia coli. Key strategies where genetic enhancement for abiotic stress tolerance has led to crop improvement are outlined in Box 1. In this case protoplasts are fused, usually in an electric field. For example, one application of biotechnology is the directed use of microorganisms for the manufacture of organic products (examples include beer and milk products). "A literature review on the safety assessment of genetically modified plants" (PDF). Siam, R. (2009). ISSN 0738-8551. [19], A factor influencing the biotechnology sector's success is improved intellectual property rights legislation—and enforcement—worldwide, as well as strengthened demand for medical and pharmaceutical products to cope with an ageing, and ailing, U.S. [12] Plant tissue culturing can produce haploid or double haploid plant lines and generations. The environment can be affected by biotechnologies, both positively and adversely. Crop improvement is the prime element of agricultural advancements and there are still many areas to be worked on in the field of crop improvement. Herbicide resistance can be engineered into crops by expressing a version of target site protein that is not inhibited by the herbicide. Due to huge population growth in the world, the yield of food materials had to be enhanced. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials and organisms such as pharmaceuticals, crops, and livestock. Biotechnology Research and Development in Academia: providing the foundation for Egypt's Biotechnology spectrum of colors. In addition, the Illinois Biotechnology Industry Organization (iBIO) is a life sciences industry association with more than 500 life sciences companies, universities, academic institutions, service providers and others as members. With long periods of drought and lack of water or nitrogen stress tolerance has become a significant part of agriculture. [32] Local agricultural systems and genetic diversity are developed and strengthened by crop improvement, which participatory crop improvement (PCI) plays a large role. Thus a gene discovered in a wild plant co… [20] To ensure the most adapted varieties are identified, advocates of organic breeding now promote the use of direct selection (i.e. The range of related issues is complex. – A curated collection of resources about the people, places and technologies that have enabled biotechnology to transform the world we live in today, Timeline of biology and organic chemistry, https://en.wikipedia.org/w/index.php?title=Biotechnology&oldid=997698628, Creative Commons Attribution-ShareAlike License. Classical breeding relies largely on homologous recombination between chromosomes to generate genetic diversity. [3][4][5] The utilization of biological processes, organisms or systems to produce products that are anticipated to improve human lives is termed biotechnology.[6]. No. In addition to studying chromosomes to the level of individual genes, genetic testing in a broader sense includes biochemical tests for the possible presence of genetic diseases, or mutant forms of genes associated with increased risk of developing genetic disorders. 37 (2): 213–217. "An Illusory Consensus behind GMO Health Assessment". The construct can be inserted in the plant genome by genetic recombination using the bacteria Agrobacterium tumefaciens or A. rhizogenes, or by direct methods like the gene gun or microinjection. Link, W.; Balko, C.; Stoddard, F.; Winter hardiness in faba bean: Physiology and breeding. 153-217. Biotechnology assisted participatory plant breeding: Complement or contradiction? There are many plant tissue culturing techniques that can be used to achieve haploid plants, but microspore culturing is currently the most promising for producing the largest numbers of them.[11]. techniques to agricultural biotechnology. Most countries have regulatory processes in place to help ensure that new crop varieties entering the marketplace are both safe and meet farmers' needs. In 1940, penicillin became available for medicinal use to treat bacterial infections in humans.[10]. The screening is based on the presence or absence of a certain gene as determined by laboratory procedures, rather than on the visual identification of the expressed trait in the plant. selection in conventional environments for traits considered important for organic agriculture). [16] The first BioFET was the ion-sensitive field-effect transistor (ISFET), invented by Piet Bergveld in 1970. The term "Biotechnology" was first used by "Karl Ereky" in 1919, meaning the production of products from raw materials with the aid of living organisms. [70][71][72][73] The legal and regulatory status of GM foods varies by country, with some nations banning or restricting them, and others permitting them with widely differing degrees of regulation.[74][75][76][77]. ", "Diversifying Selection in Plant Breeding", "A Comparison between Crop Domestication, Classical Plant Breeding, and Genetic Engineering", The Origins of Agriculture and Crop Domestication – The Harlan Symposium, Encyclopedic Dictionary of Plant Breeding, Concise Encyclopedia of Crop Improvement: Institutions, Persons, Theories, Methods, and Histories, "Cisgenic plants are similar to traditionally bred plants", "From indica and japonica splitting in common wild rice DNA to the origin and evolution of Asian cultivated rice". Biotechnology is a broad area of biology, involving the use of living systems and organisms to develop or make products. Edgar, J.D. The biotechnology sector has allowed the U.S. farming industry to rapidly increase its supply of corn and soybeans—the main inputs into biofuels—by developing genetically modified seeds that resist pests and drought. When new plant breeds or cultivars are bred, they must be maintained and propagated. Modification of Edible Oil Quality 117. Marker assisted selection can also be employed as a diagnostics tool to facilitate selection of progeny who possess the desired trait(s), greatly speeding up the breeding process. Biotechnology and Crop Improvement of Ginger (Zingiber officinale Rosc.) Overexpression of particular genes involved in cold acclimation has been shown to produce more resistance to freezing, which is one common cause of yield loss[14], Genetic modification of plants that can produce pharmaceuticals (and industrial chemicals), sometimes called pharming, is a rather radical new area of plant breeding. The commercial viability of a biotechnology industry was significantly expanded on June 16, 1980, when the United States Supreme Court ruled that a genetically modified microorganism could be patented in the case of Diamond v. In 1933 another important breeding technique, cytoplasmic male sterility (CMS), developed in maize, was described by Marcus Morton Rhoades. Chakrabarty. Application of Plant Biotechnology in Improvement of Vegetable Breeding April 2019 International Journal of Current Microbiology and Applied Sciences 8(04):1428-1435 Submitted: March 20th 2019 Reviewed: July 12th 2019 Published: October 31st 2019. [26], Plant breeding of hybrid crops has become extremely popular worldwide in an effort to combat the harsh environment. PPB is enhanced by farmers knowledge of the quality required and evaluation of target environment which affects the effectiveness of PPB. Heterosis was explained by George Harrison Shull. GM crops also provide a number of ecological benefits, if not used in excess. But with the degradation of agricultural land, simply planting more crops is no longer a viable option. The debate surrounding genetically modified food during the 1990s peaked in 1999 in terms of media coverage and risk perception,[17] and continues today – for example, "Germany has thrown its weight behind a growing European mutiny over genetically modified crops by banning the planting of a widely grown pest-resistant corn variety.

Today, production of new varieties is dominated by commercial plant breeders, who seek to protect their work and collect royalties through national and international agreements based in intellectual property rights. It is evident from this that plant breeding is vital for future agriculture to survive as it enables farmers to produce stress resistant crops hence improving food security. Stresses such as temperature variation, are signalled to the plant via a cascade of signalling molecules which will activate a transcription factor to regulate gene expression.
