|a Ubiquitin-mediated protein degradation plays a crucial role in enabling plants to effectively and efficiently cope with environmental stresses. The E3 ligases have emerged as a central component of the ubiquitination pathway and modulate plant response to abiotic stresses. However, few such studies have been reported in maize. In this study, a C3HC4-type RING finger E3 ligase in maize, ZmAIRP4 (Zea mays Abscisic acid [ABA]-Insensitive RING Protein 4), which is an ortholog of AtAIRP4, was isolated by reverse transcription polymerase chain reaction with specific primers, and its functions in tolerance to drought stress were described. ZmAIRP4 was upregulated by ABA, polyethylene glycol and sodium chloride. In vitro ubiquitination assays and subcellular localization indicated that ZmAIRP4 was an active E3 ligase predominantly localized in the cytoplasm and nucleus. Compared to wild type, ZmAIRP4-overexpressing Arabidopsis plants were hypersensitive to ABA during early seedling development, and showed enhanced drought tolerance. Moreover, the transcript levels of several drought-related downstream genes in transgenic plants were dramatically increased compared with wild type plants. Our results suggested that E3 ligase ZmAIRP4 is a positive regulator in the drought tolerance response pathway
