Identification and Cloning of Resistance Gene Analogues (RGAs) Encoding NBS-LRR Proteins from Gossypium arboreum L.

摘要

@@ Plants have developed a complicated defense mechanism during evolution to resist the harmful pathogens they encountered.The mechanism involves the interaction of the plant resistance (R) gene product with the component from the pathogen.This interaction further activates the signal transdue tion pathway,thus leading to defense responses.These defense responses include a hypersensitive response that results in localized cell death,and other general responses such as strengthening of the cell wall,formation of phytoalexins,etc.
