AP1C — Daucus carota subsp. sativus

Summary

DCAR_015918 (DcAP1C) on carrot chromosome 4 encodes a protein with a K-box domain and possesses RNA polymerase II-specific DNA-binding and transcription corepressor activities. This gene is associated with the regulation of developmental processes, including the maintenance of inflorescence and floral meristem identity, floral organ senescence, carpel development, abscission, and the timing of the vegetative-to-reproductive phase transition. It is linked to auxin polar transport regulation, root meristem size, and vascular tissue patterning. Associations include photoperiod-sensitive flowering time, days to flowering, flower and inflorescence morphology, petal number, root length, seed development, anthocyanin content, photosynthetic rate, and responses to high temperature, UV light, and brassinosteroids. Studies of related genes in other species connect the family to floral transition, meristem identity, drought tolerance, and cold tolerance.
