| Sumario: | Abstract The ubiquitin-proteasomal degradation mechanism has gained the attention over the past decade. The E2 ubiquitin conjugating enzymes are the crucial part of ubiquitination mechanism and they are believed to hold imperative association for plant development. It accepts ubiquitin from the E1 enzyme and interacts with the E3 ligase to transfer ubiquitin or directly transfers ubiquitin to the substrate. The functional aspects of E2 ubiquitin enzymes in plant systems are unclear. Tomato is being used as a model plant and rarely explored to study E2 ubiquitin enzyme. We have utilized in-silico methods to analyze E2 enzymes in Solanum lycopersicum and 59 genes were identified with UBC family domains. The physio-chemical properties, chromosomal localization, structural organization, gene duplication, promoter analysis, gene ontology and conserved motifs were investigated along with phylogenetic analysis of tomato E2 genes exploring evolutionary relations. The gene expression analysis of RNA sequencing data revealed expression profile of tomato E2 genes in seedling, root, leaf, seed, fruit, and flower tissues. Our study aid in the understanding of distribution, expansion, evolutionary relation and probable participation in plant biological processes of tomato E2 enzymes that will facilitate strong base for future research on ubiquitin-mediated regulations in tomato and other plant systems. |
