Genome-Wide Identification, Characterization, and Expression Analysis of the U-Box Gene Family in Cucumber (<i>Cucumis sativus</i>).

ABSTRACT: Plant U-box (PUB) E3 ubiquitin ligases have undergone significant expansion compared to their fungal and animal counterparts. These E3 ligases play critical roles in diverse biological processes, including responses to biotic and abiotic stresses. However, systematic identification of PUB genes in cucumber (Cucumis sativus L.) has been lacking, and their expression and functional characterization remain largely unexplored. Leveraging the recently released near-complete cucumber genome, we identified 53 putative PUB proteins classified into eight distinct groups based on domain architecture. The molecular weights of CsPUBs range from 26 to 166 kilodaltons (kDa). Exon numbers in CsPUB genes vary substantially, with CsPUB48 containing a maximum of 17 exons, while 1
