Original title: Professor Chen Gongyou's group from Shanghai Jiaotong University revealed that the basic transcription factor TFIIAγ does not participate in the activation and inhibition of Xa1 resistance to bacterial blight in rice

On February 5, 2021, the Journal of Experimental Botany published an online report titled "TALE-triggered and iTALE-suppressed Xa1 resistance to bacterial blight is independent of OsTFIIAγ1 or OsTFIIAγ5 in rice" by Professor Chen Gongyou's group from School of Agriculture and foodmate.

Xanthomonas oryzaenas oryzae pv.

The Xanthomonas TALE protein needs to form a complex with the plant basic transcription factor TFIIAγ to initiate the transcriptional expression of host target genes.

Rice Xa1 resistance can be overcome by more than 95% of Xanthomonas oryzae strains because these strains all contain iTALE, which is why the Xa1 gene is not widely used in rice bacterial blight resistance breeding.

Xu Xiameng, a doctoral student in the School of Agriculture and Biology, Shanghai Jiaotong University, is the first author of the paper, and Professor Chen Gongyou is the corresponding author.
