Among all, the induction and accumulation of pathogenesis-related (PR) proteins in plants in response to these adverse conditions is very important as PR proteins are an indispensible component of innate immune responses in plants under biotic or abiotic stress conditions. The PR proteins protect ...

When resistant plants recognize cognate or matching elicitors, intracellular signal transduction pathways are activated that ultimately result in the derepression of a battery of genes called defense response genes. These latter genes encode producing various pathogenesis related (PR) toxic proteins such as...

Pathogenesis-related 10 (PR-10) is a group of small intracellular proteins that is one of 17 subclasses of pathogenesis-related proteins in plants. The PR-10 proteins have been studied extensively and are well-recognized for their contribution to host defense against phytopathogens in several plant...
aPR proteins are induced by a broad range of stresses experienced by plants, from pathogen attacks to abnormal concentrations of plant hormones, or the presence of pollutants such as heavy metals. We have studied the effect of different treatments on%the production of PR proteins of class 1 (PR...
Harbin 150086,China )Abstract :Pathogenesis-related (PR )proteins were originally discovered to accumulate in plants that were infected by patho-gens ,but were later found to accumulate in plants in response to a variety of biotic and abiotic stresses.PR proteins were the most crucial ...
Pathogen-related (PR) proteins are an integral part of plants' defense mechanisms against various types of biotic and abiotic stresses. A little is known about the importance of these PR proteins in potato defense mechanisms. In the current study, a total of 22 pathogenesis-related 1 genes were...
