As higher plants are sessile organisms, they are unable to move to more favorable places; thus, they have developed the ability to survive under potentially detrimental conditions. Ubiquitination is a crucial post-translational protein modification and participates in abiotic stress responses in higher plants. In this study, we identified and characterized OsDIRP1 ( Oryza sativa  Drought-Induced RING Protein 1), a nuclear-localized putative RING E3 ubiquitin (Ub) ligase in rice ( Oryza sativa  L.).  OsDIRP1  expression was induced by drought, high salinity, and abscisic acid (ABA) treatment, but not by low temperature (4°C) stress, suggesting that  OsDIRP1  is differentially regulated by different abiotic stresses. To investigate its possible role in abiotic stress responses,  OsDIRP1 -overexpressing transgenic rice plants ( Ubi:OsDIRP1-sGFP ) were generated, and their phenotypes were analyzed. The T4  Ubi:OsDIRP1-sGFP  lines showed decreased tolerance to drought and salt stress as compared to wild-type rice plants. Moreover,  Ubi:OsDIRP1-sGFP  progeny were less sensitive to ABA than the wild-type during both germination and post-germination growth. In contrast,  Ubi:OsDIRP1-sGFP  plants exhibited markedly higher tolerance to prolonged cold (4°C) treatment. These results suggest that OsDIRP1 acts as a negative regulator during drought and salt stress, whereas it functions as a positive factor during the cold stress response in rice.
