NAC5 — Sorghum bicolor

Summary

SORBI_3009G142200 (SbNAC5) on sorghum chromosome 9 encodes a NAC domain-containing protein with DNA-binding transcription activator activity. This gene is associated with the regulation of root hair elongation, leaf senescence, photomorphogenesis, stomatal closure, and reproductive structure development. It has been linked to maturity time, grain filling period, seed dormancy, photosynthetic rate, root thickness, and disease tolerance, as well as responses to salinity, drought, hypoxia, sucrose, and fungi. Associations also include brassinosteroid content, ethylene sensitivity, and polyamine and cytokinin anabolism. The protein localises to the nucleus, cytosol, and cytoplasm. Studies of related genes in other species connect the family to grain filling, senescence, drought tolerance, pathogen resistance, and thermomemory.
