Biological function
The polygalacturonase gene encodes the polygalacturonase (PG) enzyme, which is responsible for the breakdown of cell wall pectin during the softening of fruits that takes place during ripening.

Pectin is a building block in plant cell walls and is what gives fruits their firmness. Fruits with reduced PG activity have a slower cell wall breakdown, higher viscosity and delayed softening.
