PPD1 — Brachypodium distachyon

Summary

BRADI_4G04640V3 (symbol PPD1, also known as BdPPD1 or BdPSBP) in Brachypodium distachyon encodes a PsbP family protein containing a PsbP_C domain and a Mog1/PsbP_a/b/a-sand domain. The product binds calcium ions and proteins, localizes to the chloroplast thylakoid lumen and is extrinsic to the thylakoid membrane, associated with the oxygen-evolving complex (OEC) of photosystem II. It is associated with photosystem I assembly. The gene is associated with anthesis time, flowering time, seed size, leaf size, leaf curvature, rosette size, stomatal density, hypocotyl elongation, silique shape, and photoautotrophic growth. Studies of related genes in other species link the family to heading time, plant height, drought tolerance, photochemical quenching, protein content, and root morphology.
