AP2 — Sorghum bicolor

Summary

SORBI_3009G125000 (SbAP2) on sorghum chromosome 9 encodes a protein kinase domain-containing protein. It is associated with CDK activity, RNA polymerase II CTD heptapeptide repeat kinase activity, and protein-cysteine S-palmitoyltransferase activity. The gene is linked to biological processes including flower formation, specification of floral organ identity, phloem development, stomatal opening, cell cycle transitions, and regulation of secondary cell wall biogenesis. It is also linked to traits such as grain number, panicle weight, seed weight and protein content, tiller number, biomass yield, stem thickness, salinity tolerance, and herbicide sensitivity. It localizes to the CESA complex, tonoplast, Golgi, and plasmodesmata. Related genes in other species are linked to floral organ identity, flowering time, and ethylene-responsive gene expression.
