RDR6 — Camelina sativa

Summary

CsRDR6 (CSA06G023530) on Camelina sativa chromosome 6 encodes an RNA-dependent RNA polymerase with RdRP activity, RNA binding, and ubiquitin ligase binding functions. The gene is associated with posttranscriptional gene silencing by RNA, ta-siRNA and siRNA processing, antiviral response, heat acclimation, and defence against bacteria. It is linked to vegetative phase change, shoot apical meristem maintenance, carpel and pistil development, pollen recognition, and wax anabolism. The protein localises to the cytoplasm, nucleus, endoplasmic reticulum, stress granules, and the RNA-dependent RNA polymerase complex. CsRDR6 is associated with traits including viral disease response, leaf morphology, abiotic stress response, anthocyanin content, and leaf composition. Related genes in other species connect the family to virus resistance, disease resistance, leaf polarity, developmental timing, and trans-acting siRNA biogenesis.
