Submergence and drought are major limitingfactors for crop production. However, very limited studies have been reported on thedistinct or overlapping mechanisms of plants in response to the two waterextremes. Here we report an ETHYLENEOVERPRODUCER 1-like gene (OsETOL1)that reversely regulates drought and submergence tolerance in rice (Oryza sativa L.). Two allelic mutants ofOsETOL1 showed increased resistanceto drought stress at the panicle developmentstage. Interestingly, themutants exhibited a significantly slower growth rate under submergence stress at both the seedling and panicle development stages. Over-expression (OE) of OsETOL1 in rice resulted in reverse phenotypes when compared to the mutants. The OsETOL1transcript was strongly induced by abiotic stresses. OsETOL1 wasfound to interact with OsACS2, a homolog of ACS which acts as a rate-limitingenzyme for ethylene biosynthesis. In the osacs2mutant and OsETOL1-OE plants, ACC andethylene content were significantly decreased, and exogenousACC restored the phenotype ofosetol1 and OsETOL1-OE under submergence stress, implying a negativeregulation role for OsETOL1 inethylene biosynthesis. The expressionof genes related to energy metabolism, such as carbohydrate catabolismand fermentation showed significant changes in the osetol1 and OsETOL1-OE plants, implying that OsETOL1 may function as a regulator of energymetabolism. These results suggest that OsETOL1 plays distinctroles in both drought and submergence stress responses partially by regulatingenergy metabolism. Expression andfunctional comparison of three ETOL family members in rice further supportedthe specific role of OsETOL1 inthe regulation of the two water stresses.
