摘      要：Strawberry is a major fruit crop worldwide because its nutritional and health benefits to human health,but its productivity is limited by Botrytis *** nonfermentation 1-related protein kinase 1(SnRK1)has a defense function against pathogens,but the function of SnRK1 in the defense response to *** in plants is still *** this study,FaSnRK1a-OE and RNAi fruits were constructed and then inoculated with *** result reveals a positive role of Fa SnRK1a in the regulation of resistance to gray ***1a affects SA content by regulating FaPAL1 and FaPAL2 *** genes related to the SA signaling pathway(FaTGA1 and FaTGA2.1)were significantly increased/decreased in FaSnRK1a-OE or FaSnRK1a-RNAi fruit,***1a interacted with the FaWRKY33.2 protein and negatively regulated FaWRKY33.2 expression,and FaWRKY33.2 acts as a repressor of disease resistance to ***,FaSnRK1a regulates the expression of six PR genes and the activities of antioxidant enzymes to boost defense response after *** *** findings showed that FaSnRK1a increases the resistance of strawberry fruit to *** via SA signaling pathway and interaction with the FaWRKY33.2 transcription factor.
