RD2 — Pisum sativum

Summary

PsRD2 (PSAT5G004200) on garden pea chromosome 5LG3 encodes a UspA domain-containing protein with dsRNA, miRNA and identical protein binding activities, and is associated with disulphide bond formation. The gene has been connected to pre-miRNA and ta-siRNA processing, gene silencing by miRNA-directed mRNA cleavage, ecdysteroid anabolism, and responses to desiccation, cytokinin, auxin and abscisic acid. It is linked to leaf proximal/distal and vascular tissue pattern formation, regulation of cell fate specification, embryogenesis, microsporogenesis, pollen development and lateral root formation. Associations with leaf margin, vein, stamen and root morphology traits, osmotic response sensitivity, flowering time, root meristem development and plant growth and development have been noted. The product localises to the ER, plastid, mitochondria, cytosol, plasmalemma, vacuole and D body.
