الوصف: Mitogen-activated protein kinases (MAPKs) play important roles in plant growth and development, plant abiotic stresses signalling pathway and plant–pathogen interactions. However, little is known about the roles of MAPKs in modulating plant growth and pathogen resistance. In this study, we found that OsMAPK12–1, an alternatively spliced form of BWMK1 in rice (Oryza sativa L.), was induced by various elicitors, such as jasmonic acid, salicylic acid, melatonin and bacterial pathogens. To further investigate the involvement of OsMAPK12–1 in plant growth and stress responses to bacterial pathogens, we constructed OsMAPK12–1 overexpression and knockdown (RNAi) transgenic rice lines. Interestingly, overexpressing OsMAP12–1 inhibited seed germination and seedling growth. Additionally, the OsMAP12-1-overexpression lines displayed enhanced disease resistance against Xanthomonas oryzae pv. oryzae PXO99 and Xanthomonas oryzae pv. oryzicola RS105, whereas the OsMAPK12-1-RNAi lines were more susceptible to these pathogens than wild type. These results suggest that OsMAPK12-1 plays a negative role in plant growth and positively modulates disease resistance against bacterial blight and streak in rice.
