SOLYC03G019890.3 — Solanum lycopersicum

Summary

SOLYC03G019890.3 on tomato chromosome 3 encodes a protein with beta-galactosidase activity and transmembrane receptor protein serine/threonine kinase activity, belonging to the glycoside hydrolase family 35 and containing lectin galactose-binding domains. The gene is associated with cell wall assembly and disassembly, pectin and galactose metabolism, cellulose breakdown and its regulation, oligosaccharide metabolism, and proline breakdown. It is linked to numerous agronomically important traits including fruit firmness, fruit weight, fruit shape and size, sugar and carotenoid content, seed size, seed dormancy and maturation, germination rate, leaf thickness and angle, tiller number, and ash content. Localisation evidence connects the product to the apoplast, plant-type cell wall, plasmodesma, vacuole, and secretory vesicle. Studies of related genes in other species link the family to fruit softening and cell wall polysaccharide modification.
