SKP1 — Beta vulgaris subsp. vulgaris

Summary

BVRB_6G134270 (SKP1) on sugar beet chromosome 6 encodes a protein containing SKP1-like and BTB/POZ domains and is annotated with multiple molecular functions including cullin family protein binding, auxin receptor activity, and MAPK phosphatase activity. The gene is associated with SCF complex assembly, regulation of gibberellic acid-mediated signalling, negative regulation of cytokinin signalling, and photoentrainment of the circadian clock. It has been linked to traits including seedling vigour, bacterial blight disease resistance, submergence tolerance, photoperiod-sensitive flowering time, plant male sterility, seed oil content, and drought tolerance. The gene is also connected to heat and cold stress tolerance, reactive oxygen species homeostasis, and organ growth. Studies of related genes in other species link the SKP1 family to immunity, floral organ development, jasmonate perception, and disease tolerance.
