Regulation of defense responses via heat shock transcription factors in Cucumis sativus L. against Botrytis cinerea
Heat shock transcription factors (HSFs) regulate the responses of plants to heat stress, but their functions in heat-shock-induced resistance (HSIR) are poorly understood. Here, we investigated the functions of HSFs in the resistance induced by a heat shock treatment (HST; 50 °C for 20 s) against gr...

Heat shock transcription factors (HSFs) regulate the responses of plants to heat stress, but their functions in heat-shock-induced resistance (HSIR) are poorly understood. Here, we investigated the functions of HSFs in the resistance induced by a heat shock treatment (HST; 50 °C for 20 s) against gray mold (Botrytis cinerea) in Cucumis sativus by measuring lesion area using image processing and quantitative gene expression analysis. The HST reduced the percentage of lesion area, consistent with the upregulation of peroxidase (POX) and pathogenesis-related (PR) 1.C1 genes at 24 and 48 h after treatment, respectively. Both genes were detected after the upregulation of the heat shock transcription factor A2 (HSFA2) and B2 (HSFB2 genes. Heat shock element (HSE) motifs were found upstream of POX, PR1.C1, POX73, and POX43, and they were upregulated at 24 h after the HST.
