PG2 — Medicago truncatula

Summary

MTR_2G103410 (symbol PG2) on chromosome 2 of barrel medic (Medicago truncatula) encodes a protein with the Glyco_hydro_28 domain and pectin lyase fold/virulence domain, and is annotated with exo-D-galacturonase activity and polygalacturonase activity. This gene is associated with pectin breakdown, cell wall modification involved in abscission, fruit dehiscence and ripening, anther dehiscence, pollen tube development, pollen germination, pollen development, pigmentation, anthocyanin anabolism, nitrogen fixation, detoxification, cell death, and carbohydrate metabolism. The encoded protein localises to the pollen wall, amyloplast, vesicle, apoplast, endoplasmic reticulum, Golgi complex, and extracellular space. Related genes in other species link the family to polygalacturonase activity (EC 3.2.1.15 and 3.2.1.67).
