RDR6 — Camelina sativa

Summary

CsRDR6 (CSA09G052070) on Camelina sativa chromosome 9 encodes an RNA-dependent RNA polymerase with RdRP activity, RNA binding, and ubiquitin ligase binding. The gene is associated with posttranscriptional gene silencing by RNA, ta-siRNA and siRNA processing, antiviral response, defence response to bacteria, heat acclimation, vegetative phase change, maintenance of shoot apical meristem identity, carpel and pistil development, pollen recognition, and wax anabolism. It localises to the cytoplasm, nucleus, endoplasmic reticulum, stress granules, and the RNA-directed RNA polymerase complex. Associations include viral disease response, leaf morphology, abiotic stress response, anthocyanin content, and leaf composition traits. Phenotypic links include ta-siRNA biogenesis, antiviral defence, leaf polarity, lateral root development, seed dormancy, fertility, and transposon silencing. Studies of related genes in other species connect the family to virus resistance, disease resistance, self-incompatibility, and narrow leaves.
