- Abstract
WRKYs are plant-specific transcription factors that play important roles in disease response. Here, we showed that a <italic>WRKY</italic> gene in rice, <italic>OsWRKY24</italic>, was upregulated in response to inoculation with rice blast fungus <italic>Pyricularia oryzae</italic>. Its expression was also induced by wounding. Green fluorescent protein-fused OsWRKY24 localized to nuclei in rice epidermal cells, and OsWRKY24 had transactivation activity in yeast cells. In addition, functional repression of OsWRKY24 through a chimeric repressor (OsWRKY24-SRDX) greatly increased susceptibility to <italic>P. oryzae</italic>. These results indicate that OsWRKY24 is a transcriptional activator that positively regulates disease resistance in rice.
