The BIK1-WRKY9 module activates jasmonate signaling to confer apple resistance to Alternaria blotch.
Apple Alternaria blotch, caused by Alternaria alternata f. sp. mali (A. alternata), is a devastating fungal disease threatening global apple production. However, the early signaling pathway underlying apple resistance to A. alternata remains unclear. In this study, through transcriptomic analysis, we identified that Md...
