Characterization of the Ubiquitin-Conjugating Enzyme Gene Family in Rice and Evaluation of Expression Profiles under Abiotic Stresses and Hormone Treatments.

ABSTRACT: Ubiquitin-conjugating enzyme E2s (UBCs), which catalyze the transfer of ubiquitin to substrate or E3 ligases, are key enzymes in ubiquitination modifications of target proteins. However, little is known about the knowledge of UBC gene family in rice. In this study, a total of 39 UBC encoding genes, which all contained an UBC domain with a cysteine active site, were identified in the rice genome. These were classified into fifteen distinct subfamilies based upon their sequence similarity and phylogenetic relationships. A subset of 19 OsUBC genes exhibited chromosomal duplication; 4 and 15 OsUBC genes were tandemly and segmentally duplicated, respectively. Comprehensive analyses were performed to investigate the expression profiles of OsUBC genes in various stages of vegetative and reproduct
