چکیده

Class III peroxidases (CIII Prxs) play critical roles in plant immunity by scavenging reactive oxygen species (ROS). However, the functions of CIII Prxs rice (Oryza sativa L.) are largely unexplored. Here, we report a Prx precursor, OsPrx30, that is responsive to bacterial blight Xanthomonas oryzae pv. (Xoo). OsPrx30 was primarily expressed roots, leaves, and stems, its protein product mainly localized at endoplasmic reticulum. Overexpression enhanced plant's susceptibility Xoo maintaining high level peroxidase (POD) activity reducing content H2O2, whereas depletion had opposite effects. Furthermore, identified an AT-hook transcription factor, OsATH1, specifically bound promoter. As observed plants overexpressing OsATH1 Xoo. Finally, demonstrated increased histone H3 acetylation AT-rich region Taken together, these results reveal mechanism underlying POD-induced natural resistance diseases suggest model for regulation genes rice.

Rice class III chitinase homologues isolated by random cloning of rice cDNAs.

We obtained seven kinds of cDNA clones putatively identified as encoding class III chitinases from cDNA libraries constructed from dichlorophenoxyacetic acid (2,4-D)- and benzyl adenine (BA)- treated rice callus. Putative amino acid sequences encoded in these cDNA clones were compared with those of known chitinases of other plants. Two clones coded for homologues that show high similarity to cl...
