Research Abstract |
A Xanthomonas oryzae pv. oryzae protein LrpX was found to function as an effector secreted through a type III secretion system into rice cells along with other effectors XopR, XopY and XopAA. Protein LrpX is likely to be associated with lipoxygenase and to represses the defense system via the jasmonate signaling cascade. Also, I identified two novel hrp regulators, XrvB and Lon protease, and found that LrpX also functions as a hrp negative regulator downstream of the proteins in the bacterial cell.
