PPD1 — Triticum aestivum

Summary

TRAESCS5A02G087200 (symbol PPD1, also known as PSBP) on bread wheat chromosome 5A encodes a PsbP_C and Mog1/PsbP_a/b/a-sand domain-containing protein that binds calcium ions and proteins. It is associated with the oxygen-evolving complex of photosystem II, the chloroplast thylakoid lumen, and thylakoid membrane. The gene is associated with vernalization response, photorespiration, generation of precursor metabolites and energy, and regulation of lipid metabolism. Associations include days to heading, flowering time, anthesis time, plant height, chlorophyll content, stripe rust, cell membrane stability, and seasonality. Phenotypic connections include flowering time, seed size, leaf size, stomatal density, and photoautotrophic growth. Studies of related genes in other species link the family to salt and cold stress tolerance, drought tolerance, heading time, and photochemical quenching.
