The use of RFLP (Restriction Fragment Length polymorphism), RAPD (Random Amplified Polymorphic DNA) , AFLP (Amplified Fragment Length Polymorphism) and isozyme markers in plant breeding are numerous. RFLPs are advantageous over morphological and isozyme markers primarily because their number is limited only by genome size and they are not environmentally or developmentally influenced. Starch content in potatoes has been increased by 20-40% by using a bacterial ADP glucose pyrophosphorylase gene. Take a look at the best of Science 2.0 pages and web applications from around the Internet! It is responsible for causing ‘hairy root disease’ in plants. have been successfully developed. Section 2 covers micropropagation (4 papers) and examines commercial and high tech systems along with synthetic seed technology. (barnase gene) for production of transgenic plants in Brassica napus. The biotechnological tools may likely to have greater impacts in horticulture, where even minor changes such as in color, aroma quality and postharvest behaviour would make significant commercial impacts Genetic transformation, micropropagation, in vitro conservation of germplasm, Bt resistant plants are already in the market. Biotechnology has caused a revolution in agricultural science. Plants that have more polyols are more resistant to stress. Plant tissue culture technique though an underutilized tool in Nigeria, it can be extensively applied in horticulture to increase crop production. Transgenic tobacco and tomato plants have been obtained using the coat protein (CP) approach, which are resistant to the Tobacco Mosaic Virus (TMV) and Tomato Mosaic Virus (ToMV), respectively. By continuing you agree to the use of cookies. Some of the achievements are: 1.        Resistance to Pathogenic Fungi and Bacteria. Tissue culture techniques have played an important role in the breeding, production and improvement of horticultural crops. Indiscriminate and injudicious use of chemical fertilizers and pesticides for the crop production and control of insect-pests has resulted in pollution of the environment deterioration of soil health and development of resistance by many insects and residue problems. Tolerance to salinity, drought, chilling, etc. with no political bias or editorial control. The development of biotechnology in terms of crop rotation ... as human hepatitis B using genetically engineered microbes is one of the list of notable achievements. Efforts are being made in this direction to transfer nif-genes cluster from bacterial or cyanobacterial strains to plants. • In 2003, 7 million farmers in 18 countries—more than 85 percent of them resource-poor farmers in the developing world—were planting biotech crops. Recent Advances on Gene Transfer Methods in Fruit Crops Authors: Sunil Kumar, Om Prakash Patidar and Ashok Yadav Introduction: Conventional fruit breeding has had little success in improving fruit crops and is constrained due to long juvenile period, genetic erosion, genetic drag and reproductive obstacles (Varshney et al., 2011).Thus, there is an urgent need for the biotechnology … The losses in agriculture due to reduction in crop-yield can be prevented to some extent by cross protection of plants from pathogenic fungi or bacteria. These tomatoes can also stay on the plant long giving more time for accumulation of sugars and acids for improving flavour. They help the plants in better plant establishment and growth when inoculated. CAB Direct
