CAF — Daucus carota subsp. sativus

Summary

DcCAF (DCAR_019361) on carrot chromosome 5 encodes a protein with ribonuclease III, helicase, and DNA glycosylase activities, containing Dicer dimerisation, RNase III, PAZ, and dsRBD domains. In carrot, the gene is associated with soluble sugar content. Annotated associations link DcCAF to small RNA processing pathways including lsiRNA, pre-miRNA, and ta-siRNA processing, gene silencing by miRNA, regulation of seed maturation, meristem development, and embryonic pattern specification. The gene is associated with numerous traits including leaf and floral morphology, vegetative vigor, viral disease response, sucrose content, seed dormancy, root mass density, and herbicide sensitivity. Studies of related genes in other species connect the family to antiviral defense, systemic RNA interference, stress tolerance, and resistance to fungal pathogens such as Sclerotinia sclerotiorum and Fusarium brachygibbosum.
