CAF — Daucus carota subsp. sativus

Summary

DcCAF (DCAR_001171) on carrot chromosome 1 encodes a protein with RNase III, helicase, and dicer dimerisation domains, and is annotated with ribonuclease III, helicase, miRNA binding, DNA glycosylase, and AP lyase activities. The gene is associated with small RNA processing pathways including LsiRNA, pre-miRNA, pri-miRNA, and ta-siRNA processing, as well as gene silencing by miRNA, regulation of seed maturation, embryonic pattern specification, and meristem development. In carrot, DcCAF has been linked to soluble sugar content. Broader associations connect the gene to traits including leaf and floral morphology, vegetative vigor, root mass density, sucrose content, seed dormancy, and responses to biotic and abiotic stresses such as viral disease, osmotic sensitivity, and herbicide exposure. The protein localises to the nucleus, nucleolus, cytoplasm, and nuclear speck.
