CAF — Capsicum annuum

Summary

CaCAF (T459_18931) on pepper chromosome 7 encodes a protein with RNase III, PAZ, dsRBD, and DEAD/DEAH-box helicase domains, characteristic of Dicer-like proteins, and is annotated with ribonuclease III, helicase, DNA glycosylase, and RNA methyltransferase activities. The gene is associated with small RNA processing pathways including pre-miRNA, pri-miRNA, lsiRNA, and ta-siRNA processing, as well as gene silencing by miRNA, hypermethylation of CpG island, and BER. It is linked to numerous developmental and agronomic traits such as leaf and floral morphology, seed dormancy, embryo development, meristem identity, vegetative vigor, stem diameter, root mass density, and responses to biotic and abiotic stresses including viral disease, osmotic stress, and herbicide sensitivity. Localization evidence connects the product to nuclear speckles, the nucleolus, and cytoplasmic ribonucleoprotein granules.
