| Abstract | ABSTRACTBT4 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 expression levels of JAR1 and PDF1.2 genes in bt4 mutant were induced; however, the expression levels of these genes in bt4 mutant were significantly lower than those in the WT, CE, and OE. These results indicated that the BT4 positively regulate the expression of genes in JA/ET signaling pathways. Therefore, the BT4 may be involved in the regulation of JA/ET signaling pathways to affect Arabidopsis resistance to B. cinerea. |
