AMY23 — Solanum lycopersicum

Summary

SlAMY23 (SOLYC03G095710.4) encodes an alpha-amylase, a calcium-binding enzyme, and is located extracellularly. The gene is associated with the regulation of starch breakdown, isoprenoid metabolism, ethene metabolism, and response to stimulus. It has been linked to a wide range of agronomic traits, including fruit weight, firmness, lycopene, carotenoid, flavonoid, and starch content, as well as leaf chlorophyll content, seedling vigor, harvest index, and ear and grain weight traits. Additional associations include amylose, sucrose, glucose, and total soluble sugar content, abscisic acid content, root number, stem diameter, leaf angle, stem elongation, respiration rate, transpiration rate, and quantum yield. Related genes in other species link the family to seed weight and phosphate content.
