PSB28 — Triticum aestivum

Summary

TaPSB28 (TRAESCS3A02G360500) on bread wheat chromosome 3A encodes a Psb28 class-1 protein. The gene is associated with the electron transport chain, stomatal closure, cellular homeostasis, signal transduction, cell death, and autotrophy, as well as sucrose and lipid metabolism. It is linked to carotenoid biosynthesis and the conversion of antheraxanthin to violaxanthin. TaPSB28 is associated with photosynthetic traits including quantum yield, net photosynthetic rate, photochemical quenching, chlorophyll content, and photosystem II stability. It is also associated with agronomically important traits such as grain yield, grain weight and size, starch content, seed dormancy and germination, days to heading, drought tolerance, and stripe rust resistance. The protein localises to the thylakoid membrane, chloroplast stroma, and plasmalemma. Related genes in other species link the family to plant growth and development traits.
