Plant tissue culture has been used for conservation, micropropagation, and in planta overproduction of some pharma molecules of medicinal plants. Moreover the vegetative propagating plants, such as banana which multiply by rhizome and one plant can yield about 10 plants per year, through micro-propagation as many as 2,00,000 plant- lets can be obtained. Welcome to BiologyDiscussion! The alternative is to provide a natural source of nitrogen within the plant. Tissue Culture Techniques and their Applications in Plant Breeding: The culturing of plant cells or tissues in synthetic medium and their development into mature plants has immense potential for plant improvement. Just a few cereals contribute to nearly fifty per cent of the total food calories. Plant transformation can be used to introduce new or novel characteristics that create a new market or displace conventional products. Production of Transgenic Plants. Similarly, seven species of grain legume account for a large portion of our calorie intake. Weeds may rapidly develop multiple herbicide resistance in some systems when several classes of herbicide act on the same molecular target. Transformation can also alter the properties of plant starches. Faculty of Biological Sciences 3,729 views Further, the starch content of wheat can be altered to suit the properties of products like noodles. Equally this technique is applicable to tree plants like teak, eucalyp­tus, etc. The quality of beer thus depends largely upon the composition of the barley grain. This field deals with the development of genetically modified plants by introducing the gene of interest in the plant. Some of the unique features of molecular markers are: (ii) They show co-dominant inheritance which helps in distinguishing homozygous from heterozygous. Increasing the levels of certain enzymes like ADP pyrophosphorylase can enhance the starch synthesis of food products. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. But this technique is specially useful for propagation of medicinal plants which grow slowly and cannot be bred in the conventional methods. Embryo rescue or embryo culture is with the objective to rescue the embryo which aborts at an early stage of development, i.e., no mature seed can be obtained. These foods are also known as functional foods. Certain bacterial genes have also proved to be quite effective in preventing pest damage. Distant hybridization programme sometimes eliminates the chromosomes of one parent, thus the culture of hybrid embryo allows to develop the haploid plant. This has given birth to Neutraceuticals – a word coined for made up food. Biotechnology is widely used in different fields to modify and produce a useful product for human benefits. window.__mirage2 = {petok:"f5c796651913d94d2e67c43881b0d22221b762cb-1609944652-3600"}; Oral vaccines against cholera have already been expressed in plants. Disclaimer 9. However, other ways of improving the nitrogen yield in plants can be achieved by increasing the efficiency of fixation process in symbiotic bacteria, increasing the efficiency of fixation process in the synthetic bacteria, modifying the nitrogen-fixing bacteria to maintain nitrogen fixation in presence of exogenous nitrogen. Let’s discuss the implications of this technology in more detail. Novel genes for nematode resistance offer an alternative approach to the production of nematode-resistant plants. Content Guidelines 2. Production of transgenic plants with resistance to viruses is one of the most successful applications of plant transformation. In this process the whole breeding procedure can be conducted in laboratory not waiting for the phenotypic expression in field, e.g., resistance property to plant pathogen can be evaluated in the absence of disease. Most applications of modern plant biotechnology can be considered to involve the manipulation of DNA sequences originally isolated from plants or other organisms. Many plants are now being used to produce useful proteins. Plant tissue culture is the most popular technique of plant biotechnology, which has diverse applications in the various fields. in Nature Reviews Molecular Cell Biology. One of the significant applications of such techniques lies in adding single genes to desirable plant types. The application of agricultural biotechnology can improve the quality of life by developing new strains of plants that give higher yields with fewer inputs, can be grown in a wider range of environments, give better rotations to conserve natural resources, provide more nutritious harvested products that keep much longer in storage and transport, and continue low cost food supplies to consumers. Genetic engineering provides an opportunity to develop transgenic plants with genetic resistance to these long-term plant pests, and thus reduce the reliance on chemical nematicides in agriculture. (a) RFLP (Restriction Fragment Length Polymorphism), (b) RAPD (Randomly Amplified Polymorphic DNA), (c) AFLP (Amplified Fragment Length Polymorphism), (d) VNTR (Variable Number Tandem Repeats), (f) SCAR (Sequence Characterised Amplified Region). The following points highlight the four main applications of biotechnology in agriculture:- 1. In this article we will discuss about the biotechnology in plant breeding.
