The following points highlight the five transformation technologies used for trans-genesis of plants. The technologies are: 1. Agrobacterium 2. Shotgun 3. Microinjection 4. DNA Uptake 5. Antisense RNA. Transformation Technology # 1. Agrobacterium: Agrobacterium tumefaciens a Gram-negative soil bacterium can induce crown galls on the stems of various plants. The phytopathogenic function of the bacterium is encoded in a tumour [...]
The below mentioned article will highlight the applications and achievements in transgenic plants production. 1. Insect and Disease Resistance: Resistance to insects and diseases has been achieved in many field crops through the use of transgenes. For example, in the famous BT-cotton, a transgenic or genetically modified variety of cotton, gene for the insect Helicoverpa resistance has been transferred from [...]
The below mentioned article highlights the five main features of transgenic plants which include: (1) Contain Transgenes (2) Involve Biotechnology (3) Bypass Sexual Process (4) Low Frequency and (5) Utility. Feature # 1. Contain Transgenes: Transgenic plants contain transgenes (foreign genes). The foreign genes maybe utilized from unrelated plants, microbes and animals. Microbial genes are utilized from fungi, bacteria and [...]
