A GWAS-identified U-box E3 ligase MsPUB6 is positively regulated by MsDREB1C and contributes to drought tolerance in alfalfa.

U-box-type E3 ubiquitin ligases (PUBs) are critical for signaling homeostasis and abiotic stress responses via substrate ubiquitination, yet their upstream transcriptional regulation remains largely unexplored, especially in alfalfa drought adaptation. Through GWAS of 171 alfalfa accessions, we identified a novel U-box...
