PEP — Sorghum bicolor

Summary

SORBI_3001G294900, designated SbPEP (also known as SbKH20 or PEP) on sorghum chromosome 1, encodes a K homology (KH) domain-containing protein with RNA binding, mRNA binding, DNA-binding transcription factor activity and protein binding functions. The gene is associated with mRNA transcription and processing, RNA processing, and regulation of the vegetative-to-reproductive phase transition, including both upregulation and downregulation of flower development, maintenance of floral organ identity, pistil development, and cell fate determination. It is linked to flowering time traits, grain weight, plant height, leaf elongation rate, net photosynthetic rate, transpiration rate, stomatal resistance, chlorophyll fluorescence, nonphotochemical quenching, anthocyanin content, seedling development, shoot development, stalk and carpel morphology, heterosis, and disease tolerance. The protein localises to the nucleus, nuclear speck and cytoplasm.
