ARF — Sorghum bicolor

Summary

SORBI_3002G078400 (symbol ARF) on sorghum chromosome 2 encodes an ADP-ribosylation factor, a small GTPase of the Arf1-5-like family with GTPase activity, GTP binding, phospholipase activator activity and G protein activity. This gene is associated with intracellular protein transport, vesicle transport, protein transport, auxin signaling and response to auxin, signal transduction, NO storage, and starch anabolism. It is linked to the Golgi complex and cytoplasm. Studies of related genes in other species connect the ARF family to agronomically important traits including grain number, grain yield, seed weight, seed size, seed germination, ear length, floret number, leaf angle, root length, rootless, potassium uptake, drought tolerance, and salt tolerance.
