APS1 — Solanum lycopersicum

Summary

SOLYC06G034110.3, designated SlAPS1 on tomato chromosome 6, encodes a protein belonging to the APS1/VSP family with acid phosphatase and nutrient reservoir activities. The gene is associated with acid secretion, excretion, plastid localization, nitrogen fixation, thiamin anabolism, isocitrate metabolism, protein metabolism, protein maturation, pH reduction, cuticle anabolism, digestion, cell wall modification, the TCA cycle, protein synthesis, detoxification, lignin anabolism, syngamy, and root hair elongation. SlAPS1 is linked to relative biomass, stigma exsertion, potassium and phosphorus content, root dry weight, amino acid, lycopene, flavonoid, proline, and chlorophyll content, iron concentration, seed weight and viability, stem diameter, leaf number, fruit weight, germination rate, root length, and plant height. Related genes in other species connect the family to drought tolerance.
