CYC1 — Daucus carota subsp. sativus

Summary

DCAR_020592 (CYC1) on carrot chromosome 6 encodes a cyclin A/B-like protein with cyclin-box and cyclin C-terminal domains, and is annotated with cyclin-dependent protein serine/threonine kinase regulator activity, histone acetylase activity, SUMO transferase activity, and kinase binding. The gene is associated with mitotic cell cycle phase transition, G1/S transition, regulation of meiotic nuclear division, asymmetric and symmetric cell division, guard mother cell division, maintenance of shoot apical meristem identity, and upregulation of DNA endoreduplication and cell proliferation. It localises to the cyclosome, CDK holoenzyme, histone acetylase complex, preprophase band, and nucleus. Associations include plant cell size, leaf trichome density, biomass yield, root meristem development, flower and floral organ development, cytokinin and brassinosteroid sensitivity, anthocyanin content, and jasmonic acid content. Studies of related genes in other species link the family to cell cycle control, root growth, biomass, and nematode resistance.
