APX — Cicer arietinum

Summary

LOC101497640 (CaAPX, also known as APX1) encodes a haem peroxidase belonging to the Ccp1-like and peroxidase_I families, with L-ascorbate peroxidase activity and additional annotated functions including p-coumarate 3-hydroxylase activity, siRNA and miRNA binding, and protein kinase activity. The gene is associated with the ascorbate-glutathione cycle, polyamine and chlorophyll metabolism, and cellular respiration. It localises to the peroxisome membrane, chloroplast thylakoid membrane, and stress granules. CaAPX is associated with grain yield per plant, canopy temperature, leaf relative water content, net photosynthetic rate, bacterial blight disease resistance, submergence tolerance, and drought tolerance. It is also associated with excess light stress tolerance, heat stress memory, seed production, water-use efficiency, and stomatal development.
