Plants use autophagy to safeguard against infectious diseases. However, how plant pathogens interfere with autophagy-related processes is unknown. Here, we show that PexRD54, an effector from the Irish potato famine pathogen Phytophthora infestans, binds host autophagy protein ATG8CL to stimulate autophagosome formation. PexRD54 depletes the autophagy cargo receptor Joka2 out of ATG8CL complexe...
1. Plant genotypic variation can shape associated arthropod and microbial communities locally, as has been demonstrated in controlled common garden experiments. However, the relative roles of plant genetics and the environment in defining communities at larger spatial scales are not well known. The environmental heterogeneity hypothesis maintains that plant genetic effects on associated communi...
Plant disease resistance to pathogens such as fungi, bacteria, and viruses often depends on whether the plant is able to recognize the pathogen early in the infection process. The recognition event leads to a rapid tissue necrosis at the site of infection, which is called the HR. The HR deprives the pathogen of nutrients and/or releases toxic molecules, thereby confining pathogen growth to a sm...
Plants are constantly being challenged by aspiring pathogens, but disease is rare. Why? Broadly, there are three reasons for pathogen failure. Either (1) the plant is unable to support the niche requirements of a potential pathogen and is thus a nonhost; or (2) the plant possesses preformed structural barriers or toxic compounds that confine successful infections to specialized pathogen species...
abstract sclerogenic fungal pathogens, are among the most important diseases of rice plant. sheath blight caused by rhizoctonia solani is one of the economically important diseases that attack a wide range of hosts. stem rot (magnaporthe salvinii) has also been found with different severity in most fields of guilan province. to determine sclerogenic fungal pathogens of rice plant, 141 isolates ...
