PEP — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0037620 (symbol PEP, HvPEP) on barley chromosome 1H encodes a K homology (KH) domain-containing protein that binds mRNA. The gene is associated with photomorphogenesis, differential growth, regeneration, embryogenesis, plastid translation, and response to heat, and its product localises to both the cytoplasm and nucleus. HvPEP is linked to photosynthetic rate, quantum yield, and respiration rate. Studies of related genes in other species connect the family to grain weight, grain yield, seed germination, chlorophyll content, net photosynthetic rate, water use efficiency, transpiration rate, stomatal resistance, carbon isotope discrimination, leaf colour and position, pollen fertility, heterosis, self-incompatibility, and head wax.
