چکیده
|
Phytophthora sojae,is a pathogen of soybean that deliver an extensive number of effector proteins into plant cells. the crinkling and necrosis (crn) cytoplasmic effectors that are conserved in water loving pathogens and their encoding genes are extremely expressed at the infective periods in p. sojae. however the molecular mechanisms are mostly unknown. here,an effector of p. sojae crn161 was characterized by transiently expressed in nicotiana benthamiana. we confirmed that pscrn161 was localized to the host cell nucleus and suppressed host cell death elicited by above tested cell death-inducing proteins,such as psavh241,r3a/avr3a,psojnip,bax and pscrn63. our results showed that pscrn161 could significantly enhanced plant resistance to the infection of p. capsici. furthermore,we found that expression levels of the plant defense-associated genes were also up-regulated in planta expression of pscrn161. this study indicate that pscrn161 may function as a suppress host plant immunity and therefore enhanced plant disease resistance. © 2017,pakistan botanical society. all rights reserved.
