The MYB transcription factor MYB48 negatively regulates the resistance to Magnaporthe oryzae by directly enhancing the transcription of HSP71.1 in rice

MYB transcription factors (TFs) play a critical role in plant immunity; however, their involvement in chaperone-mediated defense mechanisms remains unclear. Here, we demonstrated that MYB48 negatively regulates rice blast resistance by directly activating the heat shock protein gene HSP71.1. CRISPR/Cas9-generated MYB48 knockout lines exhibited enhanced resistance, with reduced lesion numbers and sizes, while overexpression lines displayed …
