PHT1-13 — Sorghum bicolor

Summary

SORBI_3006G026900, designated PHT1-13 on sorghum chromosome 6, encodes a phosphate transmembrane transporter with symporter activity, belonging to the major facilitator superfamily (MFS) of sugar transport-like proteins. The product is localized to the membrane, specifically the plasmalemma. This gene is associated with phosphate ion transport, floral organ senescence, response to ethylene and the ethylene-mediated signalling pathway, and response to symbiotic fungi. Studies of related genes in other species link the PHT1 family to phosphate uptake and translocation, though these specific associations are not yet established for sorghum.
