COI1 — Glycine max

Summary

GmCOI1 (GLYMA_11G227300V4) on soybean chromosome 11 encodes a protein with an F-box domain, leucine-rich repeats, and auxin receptor activity, and it binds DNA, transcription factors, calcium ions, and actin. The gene is associated with defense responses to insects, regulation of systemic acquired resistance, SCF complex assembly, oxylipin and triglyceride biosynthesis, and plant organ morphogenesis. It has been linked to traits including shoot elongation under submergence, male and female sterility, leaf trichome density, branch angle, lignin content, photoperiod-sensitive flowering time, temperature stress response, and insect damage response. The encoded protein localizes to the SCF complex, chloroplast envelope, and condensed nuclear chromosome. Studies of related genes in other species link the family to jasmonate signaling, insect herbivory resistance, and defense against necrotrophic pathogens.
