PG2 — Medicago truncatula

Summary

MTR_7G113910 (PG2) on barrel medic chromosome 7 encodes a protein with a Glyco_hydro_28 domain and pectin lyase fold. The gene is associated with polygalacturonase activity and protein binding, and has been linked to cell wall modification involved in abscission, fruit dehiscence, anther dehiscence, fruit ripening, and cell wall organization. It is also connected to pigmentation, anthocyanin anabolism, nitrogen fixation, detoxification, cell death, and carbohydrate metabolism. The encoded protein localizes to the amyloplast, apoplast, and extracellular space. Additionally, PG2 is associated with amino acid content. Related genes in other species link the family to endo-polygalacturonase activity (EC 3.2.1.15).
