RD2 — Phaseolus vulgaris

Summary

PHAVU_009G023400 (PvRD2) on chromosome 9 of French bean encodes a UspA domain-containing protein with a Rossmann-like α/β/α fold. The gene is associated with dsRNA binding, miRNA binding, identical protein binding, and disulphide bond formation, and is linked to pre-miRNA processing, gene silencing by miRNA, ta-siRNA processing, and response to desiccation, cytokinin, auxin, and abscisic acid. It has been connected to leaf margin and vein morphology, stamen morphology, root phototropism, osmotic and cytokinin sensitivity, flowering time, and plant growth and development traits. Localisation evidence links the product to D bodies, secretory vesicles, vacuoles, ER, plastids, mitochondria, cytosol, and the plasmalemma. Studies of related genes in other species link the family to abscisic acid sensitivity, phosphate homeostasis, miRNA strand selection, posttranscriptional mRNA regulation, and thermomorphogenesis.
