MiR394 Acts as a Negative Regulator of Arabidopsis Resistance to B. cinerea Infection by Targeting LCR.

ABSTRACT: Gray mold of tomato is caused by the pathogen Botrytis cinerea. MicroRNAs play a crucial role in the biotic and abiotic stress responses of plants and regulate their targets by gene silencing. miR394 is an ancient and conserved miRNA in plants, and it participates in the regulation of plant development and stress responses. In our previous study, miR394 was found to respond to B. cinerea infection in tomato, but the roles and regulatory mechanisms of miR394 in B. cinerea-infected tomato remain unclear. miR394 was down-regulated in tomato in response to B. cinerea infection, showing an expression pattern opposite to the previous finding that miR394 was up-regulated in tomato cv. Jinpeng 1 infected by B. cinerea. We obtained transgenic Arabidopsis
