The isolation of specific promoter elements has also helped design crops that express proteins in specific tissues. Biotechnology shows its technical advantages and new development prospects in breeding of new medicinal plants varieties with high and stable yield, good quality, as well as stress-resistance. Distant hybridization programme sometimes yields non-viable embryo, then the em­bryo culture method and embryo rescue help to obtain the viable hybrids. Transforming the nitrogen fixing genes (nif genes) from leguminous to non-leguminous crops can offer a cost-effective alternative to the expensive fertilisers. One of the significant applications of such techniques lies in adding single genes to desirable plant types. This approach can be applied for modifying flowering response, fruit development and expression of storage protein genes. Several strategies involving the expression of the viral genome in the plant have proven effective. which will prove beneficial in increasing crop production without affecting human health. Such environmentally inducible promoters will certainly become useful tools to study gene expression, and this work will lay the foundation for the transfer of stress-responsive genes under regulated promoters to susceptible species. Our mission is to provide an online platform to help students to share notes in Biology. Molecular markers are used for the analysis of genetic variation in germplasm available for plant improvement. The most important roles of Biotechnology in food production and industry are to improve crop yield, nutrient value, resistance to diseases, pesticides and drought conditions. In vitro gene transfer technique allows transferring desirable genes across taxonomic boundaries into plant from other plants, animals, microbes or any artificial, synthetic or chimeric gene also. The quality of wheat is determined by the presence of seed-storage proteins of the grain. Plants are a rich source of antigens for the immunization of animals. Such technology may be used to modify the expression of genes already present in the plants, or to introduce new genes of other species with which the plant cannot be bred conventionally. Before sharing your knowledge on this site, please read the following pages: 1. Some of the applications of biotechnology in agriculture that you will study in detail are the production of pest resistant plants, which could decrease the amount of pesticide used. Production of transgenic plants with resistance to viruses is one of the most successful applications of plant transformation. These stress factors include temperature, salinity, drought, flooding, UV light, and various infections. Genetic engineering of plants provides an opportunity to alter their properties or performance in order to improve upon their utility. Transferring these genes to the potato crop can protect it from aphid menace. " Application of biotechnology in plant disease control " Save as: AGRIS_AP RIS EndNote(XML) Prediction of Hybrid Performance (Heterosis): Genetic distance between possible parents can be estimated by employing molecular markers. That is exactly what plant biotechnology does – the transfer of single or multiple genes to plants lacking important components. Some other seed crops like rice offer a better balance of amino acids, but fall-out on their overall protein levels. Induction and Selection of Mutant 3. APPLICATIONS of Biotechnology 1. The haploid plantlet production is aimed through another culture or pollen culture, where the embryoids developed from this culture (haploid) may be treated with colchicine to get diploid homozygous plants which may be used in breeding programme.
