PG2 — Solanum lycopersicum

Summary

SOLYC03G116500.4, also known as PG2, is a tomato gene on chromosome 3 that encodes a protein with polygalacturonase activity and belongs to the Glyco_hydro_28 family. The encoded protein is localised to the apoplast, extracellular region and amyloplast. PG2 is associated with cell wall disassembly and organization, arabinan metabolism, lycopene breakdown, pigment metabolism, ethene catabolism, and sepal morphogenesis. The gene has been linked to numerous fruit quality and agronomic traits, including fruit firmness, fruit weight, fruit size, fruit shape, fruit color, lycopene content, carotene content, carotenoid content, anthocyanin content, flavonoid content, sugar content, sucrose content, starch content, protein content, nitrogen content, cellulose content, ash content, rubisco content, respiration rate, photosynthetic rate, transpiration rate, ethylene sensitivity, germination rate, seed shattering, seed maturation, stigma exsertion, inflorescence branching, and turgor pressure.
