COI1 — Brassica oleracea

Summary

BoCOI1, encoded by the cabbage gene BOLC102_C04P007960.1_BOLC102_V1 on chromosome 4, is a member of the COI1 F-box protein family, containing a Transp_inhibit domain and leucine-rich repeat superfamily domain, and exhibits auxin receptor activity, DNA binding, and transcription factor activity. This gene is associated with defense response to insects, jasmonic acid/ethylene-dependent systemic resistance, regulation of systemic acquired resistance, and oviposition. It is also linked to plant organ morphogenesis, leaf morphogenesis, and SCF complex assembly. Traits connected to BoCOI1 include plant male and female sterility, floral organ number, stamen morphology, leaf trichome density, branch angle, peduncle length, petal size, photoperiod-sensitive flowering time, and temperature stress response. Studies of related genes in other species link the family to jasmonate-mediated root growth inhibition, defense against insects and pathogens, pollen fertility, male sterility, and floral organ abscission.
