PPD1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G043780 (symbol PPD1, also known as TtPPD1 or TtPSBP) on durum wheat chromosome 5B encodes a PsbP C-terminal domain-containing protein with calcium ion and protein binding activities. It is associated with photosystem I assembly and is localized to the chloroplast thylakoid lumen, thylakoid membrane, and oxygen-evolving complex of photosystem II. The gene is linked to heading time and anthesis time, as well as to seed size, leaf size, rosette size, stomatal density, hypocotyl elongation, leaf curvature, silique shape, photoautotrophic growth, and flowering time. Studies of related genes in other species connect the family to days to heading, flowering time, plant height, drought tolerance, protein content, photochemical quenching, and various morphological traits including leaf margin, silique, hypocotyl, and root morphology.
