The following points highlight the five novel transgenic approaches for herbicide tolerance. The approaches are: 1. Glyphosate Resistance 2. Glyphosate Resistance by over expression of EPSPS Gene 3. Cytochrome p450 Mediated Tolerance 4. Engineering Herbicide Tolerance by p450 5. Overexpression of At PgP, or Apyrase. Approach # 1. Glyphosate Resistance: Majority of the weeds in […]

Artificial Nematode Resistance in Transgenic Plants | Genetics
Article Shared by
In this article we will discuss about the artificial nematode resistance in transgenic plants. Artificial nematode resistance could be achieved by an alternative molecular strategy; an approach provides duration and efficient resistance. Deployment of antinematode gene in transgenic plant depending on specificity of nematode can provide artificial defence system. Some of the promising approaches are […]
Models for Post-Transcriptional Gene Silencing (PTGS) | Genetics
Article Shared by
In this article we will discus about the models for post-transcriptional gene silencing (PTGS). Production of dsRNA from inverted transgene repeats and single copy transgene triggers PTGS. It was proposed that dsRNA would be act as template for an RNA-directed RNA polymerase. Atleast four models have been proposed to explain induction of PTGS. First model […]
