co-2 — Triticum aestivum

Summary

TRAESCS2D02G468200 (symbol co-2, preferred name TaPH=BHC(PO)) on bread wheat chromosome 2D encodes a protein with polyphenol oxidase domains, aureusidin synthase activity, catecholase activity, and copper and metal binding. The protein localises to the chloroplast thylakoid lumen and vacuolar lumen. This gene is associated with pigment anabolism, secondary metabolism, starch anabolism, photorespiration, systemic acquired resistance, induced systemic resistance, response to biotic stimulus, response to endogenous stimulus, and digestion. It is linked to grain yield, grain weight, grain size, grain protein content, plant height, spike length, awn length, awn color, days to heading, days to maturity, anther extrusion, stripe rust, drought tolerance, abscisic acid content, carotenoid content, and root length. Studies of related genes in other species connect the family to seed coat color, cold tolerance, and phenol reaction.
