BTB and TAZ domain protein BT4 positively regulates the resistance to Botrytis cinerea in Arabidopsis.

ABSTRACT: BT4 gene was identified to play an important role in Arabidopsis resistance to pst DC3000 in preliminary studies. However, the specific function and molecular mechanism of BT4 gene in regulation of Arabidopsis resistance to Botrytis cinerea had not been described to date. In this study, we found that the expression of BT4 was induced by wounding and B. cinerea inoculation in Arabidopsis. After inoculated with B. cinerea, T-DNA insertion mutants of the BT4 gene, bt4, showed significant susceptibility symptoms, whereas no significant symptoms were found in wild-type (WT), the complemented transgenic plants (CE), and the overexpression transgenic plants (OE). After inoculated with B. cinerea, the expres
