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 the world can be destroyed [...]
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. [...]
In this article we will discuss about the viral resistance in transgenic plants. Plant viruses are the potential candidate in affecting crop yield. Several conventional methods such as breeding for resistance, heat treatment are enforced to combat viral menace. Production of genetically modified plants with improved resistance to viral disease is one of the key goals in plant biotechnology. Protection [...]
