In this article we will discuss about the molecular basis of cytoplasmic male sterility in nature. Cytoplasmic male sterility (CMS) has been noticed over 150 plant species. CMS is a condition where plant is unable to produce functional pollen. Exploration of CMS in the producÂtion of male sterile lines eliminates hand emasculation. CMS can arise spontaneously from breeding lines due [...]
In this article we will discuss about the genetic engineering strategy for the production of male sterility plants. Extensive progress has been made in cell and tissue specific gene expressing and discovÂery of novel genes which can potentially inflict tissue ablation through genetic engineering led to the successful production of male sterile plants partially or completely. The basic concept adapted [...]
Two types of HDGS have been categorised: 1. Transcriptional Gene Silencing (TGS) 2. Post-Transcriptional Gene Silencing (PTGS). Type # 1. Transcriptional Gene Silencing (TGS): Transcriptional gene silencing (TGS) is a gene silencing mechanism in which inactivation of (trans) gene specific RNA synthesis takes place. These are predominently observed in transgenic plants containing multiple copies of homologous transgene or endogenous gene. [...]
