| Abstract: | Yr10 confers resistance to stripe rust starting at seedling stage,which is also called all-stage resistance,performing resistance to the most popular stripe rust.To explore the resistance pathway mediated by Yr10,a wheat cultivar AvocetS(AvS) and its near-isogenic line AvSYr10NIL (AvS+Yr10 ) were individually inoculated with CYR31 to serve as the compatible and incompatible interaction system.The resistance mechanism mediated by Yr10 was analyzed by comparing the difference in the expression of signal molecules in the incompatible interaction and related genes expression between the incompatible and the compatible interactions.In the incompatible interaction,RAR1, SGT1 and HSP90 may participate to regulate and active the downstream signaling pathways mediated by R gene.The activation of R gene triggers the rapid accumulation of reactive oxygen species(ROS) at early stage after inoculation,and the endogenous SA level peaks appeared at early stage after inoculation.Then the host cells burst out ROS after inoculation,and the downstream disease-related gene PR1 were significantly up-regulated.Meanwhile,it caused a rapid cell death,manifested as hypersensitive response (HR).Overall,after the activation of R gene,the accumulation of ROS through SA signaling molecules in the Yr10 resistance pathway ultimately led to the expression of downstream PR gene and HR. |
