APX — Glycine max

Summary

GLYMA_12G073100V4 (GmAPX) encodes a haem peroxidase family protein with L-ascorbate peroxidase activity, as well as p-coumarate 3-hydroxylase, siRNA and miRNA binding, RNA endonuclease, and protein kinase activities. The gene is associated with the ascorbate-glutathione cycle, xanthophyll cycle, chlororespiration, cellular and alternative respiration, chlorophyll metabolism, cell wall repair, citrate secretion, and positive regulation of stomatal complex development. It localises to the peroxisome membrane, chloroplast thylakoid membrane, stress granule, plasmodesma, and extracellular regions. GmAPX is associated with relative chlorophyll content, net photosynthetic rate, quantum yield, water use efficiency, transpiration rate, shoot dry weight, root volume, biomass yield, seed viability, bacterial blight disease resistance, aphid response, submergence tolerance, carotenoid and linolenic acid content, and days to flowering.
