BBM — Sorghum bicolor

Summary

SORBI_3003G390600 (SbBBM) encodes a transcription factor with DNA-binding and protein-binding activities, belonging to the AP2/ERF domain family. In sorghum, this gene is associated with the regulation of seed development, embryonic development, shoot apical meristem identity, phyllotactic patterning, floral organ abscission, secondary cell wall biogenesis, callus formation, and adventitious root development. It localizes to the nucleus, cytoplasm, and transcription regulator complexes. SbBBM is linked to grain yield, plant height, lignin content, and disease tolerance. Studies of related genes in other species connect the family to root meristem maintenance, somatic embryogenesis, shoot regeneration, and responses to abscisic acid and salt stress, as well as traits such as spike density, grain width, biomass yield, and water use efficiency.
