AP37 — Sorghum bicolor

Summary

SbAP37 (SORBI_3009G184400) on sorghum chromosome 9 encodes a protein with an AP2/ERF domain and DNA-binding, transcription coactivator and corepressor activities, and protein homodimerization activity. It localises to the nucleus, nucleolus, cytosol and mediator complex. The gene is associated with diverse biological processes including cellular responses to drought, salinity, hypoxia and ethylene signalling, as well as regulation of defence responses, flower development, trichome branching, seed oilbody biogenesis, and phloem or xylem histogenesis. Associations with agronomic traits include drought tolerance, yield, root development, flowering time, disease tolerance, and responses to auxin, brassinosteroids and jasmonic acid. Studies of related genes in other species link the family to grain weight, plant height, cold tolerance, anthocyanin content, and resistance to pathogens and herbivores.
