MO1 — triticum aestivum

Summary

TRAESCS5D02G391600 (symbol MO1, also known as ABA2 or TaMO1-5D) on bread wheat chromosome 5D encodes a FAD-binding domain-containing protein with zeaxanthin epoxidase activity, monooxygenase activity and FAD binding. The product belongs to the MOase family and is localised to the chloroplast membrane and thylakoid membrane. This gene is associated with abscisic acid anabolism, hormone metabolism, embryogenesis, protein synthesis, secondary metabolism and defense response. It has also been linked to drought tolerance. Related genes in other species, linked by sequence similarity, associate the family with zeaxanthin epoxidase activity (EC 1.14.15.21).
