Artificial Nematode Resistance in Transgenic Plants | Genetics

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 the deployment of compounds produced [...]

Models for Post-Transcriptional Gene Silencing (PTGS) | Genetics

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 is known as threshold model [...]

Nematode Resistance in Plants | Genetics

In this article we will discuss about the nematode resistance in plants. Nematodes predate on large number of plants and inflict considerable damage to eco­nomically important crops. Plant nemotades are either living outside the root (ectoparasite) or living inside the root (endoparasite). The endoparasitic nematodes divided into two groups. One is cyst nematodes include, heterodera and globodera and root knot [...]
