GIF1 — Sorghum bicolor

Summary

SORBI_3008G100700 (SbGIF1) on sorghum chromosome 8 encodes a protein with an SS18_N domain and transcription coactivator activity that binds cis-regulatory regions, ATP, and other proteins. It is associated with nucleosome organization, regulation of gene expression, cell cycle and cell population proliferation, floral meristem determinacy, and responses to gibberellin, red and far-red light, and nematodes. The gene has been connected to seed, leaf, and root development, as well as fruit yield, flowering time, leaf senescence, drought tolerance, disease resistance, salinity tolerance, phosphate acquisition, and root morphology traits. It localizes to the nucleus, cytoplasm, chloroplast envelope, and mitochondria. Related genes in other species are linked to organ size, plant regeneration, salt tolerance, and grain yield traits.
