GAPC — Solanum lycopersicum

Summary

SOLYC03G111010.4, designated SlGAPC, encodes a glyceraldehyde-3-phosphate dehydrogenase (GAPDH) with NAD+ and NADP binding, fructose-bisphosphate aldolase, phospholipase D, and histone acetyltransferase activities. In tomato, this gene is associated with diverse traits including fruit weight, firmness, color, lycopene and carotenoid content, seed weight, leaf dimensions, stem diameter, petiole length, root weight, and seedling vigor. It is linked to stress tolerance phenotypes such as drought, salinity, freezing, and UV-B responses, as well as stomatal closure, reactive oxygen species production, and pathogen resistance. The gene product localizes to the plasma membrane, vacuole, chloroplast envelope, apoplast, and cell wall. Studies of related genes in other species connect the GAPC family to glycolytic flux, actin organization, basal immunity, and thermotolerance, as well as grain yield and pollen germination.
