COI1 — Cicer arietinum

Summary

CaCOI1 (LOC101492486) on chickpea chromosome 2 encodes a protein with auxin receptor activity, auxin and IP6 binding, DNA-binding transcription factor activity, and calcium ion binding. It contains an F-box domain and leucine-rich repeats. CaCOI1 is associated with regulation of the jasmonic acid-mediated signaling pathway, defense response to insects, systemic acquired resistance, SCF complex assembly, and plant organ morphogenesis. It has been linked to numerous traits including shoot elongation under submergence, leaf trichome density, floral organ number, stamen morphology, lignin content, photoperiod-sensitive flowering time, temperature stress response, and insect damage response. Additional associations include pathogen resistance, seed production, stamen development, salt stress tolerance, and root development. Studies of related genes in other species link the family to jasmonate-mediated root growth inhibition, insect herbivory resistance, and defense against necrotrophic pathogens.
