AP1C — Daucus carota subsp. sativus

Summary

DCAR_000894 (DcAP1C) on carrot chromosome 1 encodes a protein with a K-box domain and exhibits DNA-binding, protein dimerization, and transcription corepressor activities. In carrots, this gene is associated with the regulation of floral organ identity and meristem determinacy, vernalization response, auxin transport, photomorphogenesis, and seed growth. It has been linked to numerous traits including flowering time, flower and inflorescence morphology, petal number, sepal and stamen development, root length, anthocyanin content, photosynthetic rate, chloroplast development, and responses to UV light, high temperature, cytokinin, and brassinosteroids. Studies of related genes in other species connect the family to floral transition, meristem maintenance, drought tolerance, cold tolerance, and floral organ abscission.
