PDR2 — Sorghum bicolor

Summary

SORBI_3001G190900 (SbPDR2) on sorghum chromosome 1 encodes an ABC transporter of the PDR subfamily with ATP-coupled transmembrane transporter and efflux permease activities. This gene is associated with abscisic acid transport, hormone transport, carbohydrate export, and defense response, as well as pigmentation, regulation of secondary shoot formation, and downregulation of post-embryonic development. SbPDR2 is associated with phosphate deficiency response, phosphate sensing, root development, primary root growth under phosphate deficiency, root meristem maintenance, root system architecture, and root-soil cohesion. The encoded protein localizes to the membrane, plasmalemma, mitochondria, and nucleus. Related genes in other species are linked to seed germination, phosphorus response, root meristem development, and seed growth and development traits.
