RNA Silencing: A Natural Resistance Mechanism in Plantss strengthens its importance. Nowadays, RNA silencing induced by double stranded RNA (dsRNA) molecules such as short hairpins, short interfering RNAs (siRNAs) and long dsRNAs has developed into a standard tool in gene function studies (gene knock-down). It is being applied in large automated genome

Recognition and Signal Transduction Associated with , Gene-mediated Resistance a defense response. One of the earliest defense responses is the hypersensitive response (HR), a type of programmed cell death (PCD) that occurs at the pathogen’s infection site. HR is correlated with the signaling of an .-gene-mediated disease resistance response and containment of the pathogen at

The localized infection is an efficient mechanism whereby plants res

Viral Counter-Defense Moleculesnce it is in such assays that a role for all these proteins in suppressing an RNA surveillance system has been demonstrated. The connection between a role for these proteins in suppressing the silencing of a transgene and inhibition of plant defense mechanisms preventing natural virus infection has

Reducing Virus Associated Crop Loss Through Resistance to Insect Vectorsenvironmental concerns. The development of pest resistant plants is an attractive alternative strategy for the control of insects and the direct damage they cause. For a target pest that is also the vector of a plant pathogenic virus, the question arises as to whether an effective insect resistance

Resistance to Viruses in Potatoe transmitted by aphids. This led to the development of seed industries in many countries where highgrade virus-free seed tubers were produced in areas that are climatically and geographically suitable with regards to isolation from sources of infection and reduced numbers of virus vectors.

Common Beansbean is the preferred form of consumption, with over 70% of the total common bean production area corresponding to this commercial class. In general terms, the genetic base of common bean cultivars is narrow, because only a small proportion of wild common bean populations were domesticated (.).
