APL2 — Triticum aestivum

Summary

TRAESCS1D02G427400, designated TaAPL2 (also known as TaAGPL3, TaAGPL2-1D, and APL2), encodes the large subunit of ADP-glucose pyrophosphorylase (AGPase; EC 2.7.7.27), a key enzyme in starch biosynthesis. This gene is located on bread wheat chromosome 1D. TaAPL2 is associated with starch and amylopectin anabolism, glycogen metabolism, and localization to the amyloplast and glucose-1-phosphate adenylyltransferase complex. It has been linked to thousand kernel weight and seed number per spike. Related genes in other species are associated with seed development, ABA response, and starch content in leaves and stems.
