PG2C — Cucumis sativus

Summary

CSA_5G409610, also known as PG2C, encodes a polygalacturonase with exo-D-galacturonase activity, belonging to the Glyco_hydro_28 family. This cucumber gene on chromosome 5 is associated with leaf abscission, fruit dehiscence, anther dehiscence, pectin breakdown, and polysaccharide breakdown. It is also linked to pigmentation, carotenoid anabolism, ethylene anabolism, and pollen tube development. The encoded protein localizes to the apoplast, pollen wall, vesicles, ER, and Golgi complex. Associations with agronomically relevant traits include carotene content, fruit firmness, and fruit weight. Studies of related genes in other species, such as PG1 and PG9, connect the family to pectin degradation and cell wall disassembly.
