MIEL1 — Brassica oleracea

Summary

BoMIEL1, encoded by gene BOLC102_C02P010670.1 on cabbage chromosome 2, is a RING-type zinc-finger protein with ubiquitin ligase activity and transcription factor binding capability. It localises to both the cytoplasm and nucleus. The gene is associated with upregulation of proteasomal ubiquitin-dependent protein catabolic process, glucose-mediated signalling, inhibition of defence response to bacteria, wax anabolism, and anthocyanin anabolism. Traits linked to BoMIEL1 include leaf colour, proline content, and drought tolerance. Phenotypic associations encompass seed germination, cuticular wax biosynthesis, auxin metabolism, lipid droplet mobilization, abscisic acid signaling, and biotic stress response, including increased resistance to Pst AvrRpm1. Studies of related genes in other species further connect the family to auxin content, root length, seed growth and development trait, and abscisic acid sensitivity.
