Integrated miRNAome and Transcriptome Analysis Reveals Argonaute 2-Mediated Defense Responses Against the Devastating Phytopathogen Sclerotinia sclerotiorum.

ABSTRACT: Argonaute 2 (AGO2)-mediated role in plant defense against fungal pathogens remains largely unknown. In this study, integrated miRNAome and transcriptome analysis employing ago2 mutant was performed to reveal AGO2-associated miRNAs and defense responses against the devastating necrotrophic phytopathogen Sclerotinia sclerotiorum. Both miRNAome and transcriptomes of S. sclerotiorum-inoculated ago2-1 mutant (ago2-Ss) and wild-type (WT-Ss) as well as mock-inoculated ago2-1 mutant (ago2) and wild-type (WT) Arabidopsis plants, were analyzed by sRNA and mRNA deep sequencing. Differentially expressed genes (DEGs) and differentially expressed miRNAs (DEMs) of the comparisons WT-Ss/WT, ago2/WT, ago2-Ss/WT-Ss, and a
