PEP — Sorghum bicolor

Summary

SORBI_3001G249200, designated SbPEP on sorghum chromosome 1, encodes a K homology domain-containing protein that binds mRNA. The gene is associated with chlorophyll fluorescence, nonphotochemical quenching, seedling development, and photosynthesis. It has been linked to grain weight per spike, grain weight, net photosynthetic rate, transpiration rate, respiration rate, stomatal resistance, and heterosis. The protein localises to both the cytoplasm and nucleus. Studies of related genes in other species connect the family to grain yield, chlorophyll content, water use efficiency, quantum yield, carbon isotope discrimination, seed germination, pollen fertility, leaf colour and position, and head wax.
