摘　　要：Walnut anthracnose induced by Colletotrichum gloeosporioides is a disastrous disease that severely restricts the development of the walnut industry in China.Long non-coding RNAs(lncRNAs)are involved in adaptive responses to disease,but their roles in the regulation of walnut anthracnose resistance response are not well defined.In this study,transcriptome analysis demonstrated that a C.gloeosporioides-induced lncRNA,lncRNA109897,located upstream from the target gene JrCCR4,upregulated the expression of JrCCR4.JrCCR4 interacted with JrTLP1b and promoted its transcriptional activity.In turn,JrTLP1b induced the transcription of lncRNA109897 to promote its expression.Meanwhile,transient expression in walnut leaves and stable transformation of Arabidopsis thaliana further proved that lncRNA,JrCCR4,and JrTLP1b improve the resistance of C.gloeosporioides.Collectively,these findings provide insights into the mechanism by which the lncRNA109897-JrCCR4-JrTLP1b transcriptional cascade regulates the resistance of walnut to anthracnose.
