In this article we will discuss about the concept of RNA interference technology. RNA (RNAi) interference is an exciting field in biotechnology. This is a new approach for achieving shut down of target gene. In RNA interference method only a few double-stranded RNA (dsRNA) molecule will be employed per cell to silence the expression of target gene. Therefore, it is [...]
Pathogenesis related proteins are the class of proteins produced by plants against pathogen attack. These proteins play a crucial role in plant defence against pathogen. Expression of PR genes is not only due to pathogen attack but also takes place by abiotic stress such as wounding, osmotic stress, UV light and oxidation stress. Several plant parts such as root flowers, [...]
The following points highlight the five mechanisms of metal phytoremediation by plants. The mechanisms are: 1. Phytoextraction 2. Phytostabilization 3. Rhizofiltration 4. Phytovolatization 5. Phytodegradation. Mechanism # 1. Phytoextraction: This approach is primarily used for the treatment of contaminated soils. This process uses plants to absorb, concentrate, and precipitate toxic metal from contaminate soil and loaded into shoots, leaves etc. [...]
