Expression of OsWRKY71, a rice WRKY gene, was induced by biotic elicitors and pathogen infection. It was also found that OsWRKY71 has features characteristic of a transcriptional repressor. Microarray analysis revealed that several elicitor-induced defense-related genes were upregulated in rice cells overexpressing OsWRKY71. These results indicate that the activation of defense-related genes by OsWRKY71 was probably indirect.
水稻WRKY基因OsWRKY71的表达受生物诱导子和病原菌侵染的诱导。研究还发现,OsWRKY71具有转录抑制因子的特征。基因芯片分析显示,在过表达OsWRKY71的水稻细胞中,几个诱导子诱导的防御相关基因上调。这些结果表明,OsWRKY71对防御相关基因的激活可能是间接的。
