PETD — Triticum aestivum

Summary

TRAESCS7A02G230800 (symbol PETD, chromosome 7A) encodes cytochrome b6/f complex subunit IV, a component of the photosynthetic electron transport chain. The gene product localises to the thylakoid membrane and is associated with redox activity and electron transfer. In bread wheat, PETD has been linked to a wide range of agronomically important traits including grain iron and zinc content, grain protein content, grain yield per plant, test weight, harvest index, spike length, grains per spike, heading time, stand establishment, plant vigor, and net photosynthetic rate. It is also associated with stress responses such as drought sensitivity and salt stress response, as well as with leaf color, pericarp color, seed coat color, coleoptile color, and root number.
