Polygalacturonase activity and expression of related genes during ripening of strawberry cultivars with contrasting fruit firmness
NM Villarreal, HG Rosli, GA Martínez… - Postharvest Biology and …, 2008 - Elsevier
Fleshy fruits soften during ripening mainly as a consequence of the catabolism of cell wall
components. In strawberry (Fragaria× ananassa Duch), the depolymerization and
solubilization of pectins increase during ripening and contribute to fruit softening. In the
present paper, we report the cloning and expression analysis of two polygalacturonase (PG)
putative cDNAs: FaPG1 and T-PG. The former seems to be the same sequence of previously
reported PG in strawberry, while T-PG cDNA has a deletion of 85bp that cause a frame shift …
