AMY23 — Capsicum annuum

Summary

CaAMY23 (T459_13060) on pepper chromosome 4 encodes an alpha-amylase (EC 3.2.1.1) with calcium ion binding activity, belonging to the glycoside hydrolase family 13 catalytic domain family. The gene is associated with starch breakdown, sucrose breakdown, glucose metabolism, carbohydrate metabolism, proteolysis, fermentation, digestion, pH reduction, wound healing, NO storage, and fruit development. It has been connected to pungency, respiration rate, photosynthetic rate, and seed weight. Studies of related genes in other species link the family to numerous agronomic traits including fruit weight and firmness, starch, amylose, sucrose, glucose, lycopene, carotenoid, flavonoid, and proline content, leaf chlorophyll content and chlorosis, seedling vigor, stem diameter and elongation, root number, ear weight and length, harvest index, transpiration rate, quantum yield, abscisic acid content, phosphate content, and total soluble sugar content.
