COI1 — Beta vulgaris subsp. vulgaris

Summary

BvCOI1 on sugar beet chromosome 2 encodes a protein with an F-box domain and leucine-rich repeats, associated with auxin receptor activity and DNA-binding transcription factor activity. It is associated with jasmonic acid signaling, SCF complex assembly, and defense responses to insects and pathogens. The gene is linked to regulation of leaf morphogenesis, shade avoidance, systemic acquired resistance, and male meiotic division. Traits associated with BvCOI1 include herbivore and pathogen resistance, floral volatile production, plant growth regulation, carbon allocation, seed production, stamen development, and photoperiod-sensitive flowering. It also shows associations with branch angle, leaf trichome density, petal number, peduncle length, and lignin biosynthesis. Studies of related genes in other species link the family to jasmonate-mediated root growth inhibition, defense against necrotrophic pathogens, trichome development, and resistance to herbivory and fungal pathogens.
