General Information

General Information Comment Organism
malfunction suppressing expression of PMEs in tomato fruit reduces the amount of Ca2+ bound to the cell wall, and also reduces fruit susceptibility to Blossom-end rot Solanum lycopersicum
physiological function high expression of pectin methylesterases increases Ca2+ bound to the cell wall, subsequently decreasing Ca2+ available for other cellular functions and thereby increasing fruit susceptibility to Blossom-end rot Solanum lycopersicum
