Quality and <scp>PR</scp> gene expression of table grapes treated with ozone and sulfur dioxide to control fungal decay

Abstract

Ozone and sulfur dioxide treatments can influence the expression patterns of PAL, chitinase and β-1,3-glucanase to different extents in different grape cultivars and under different exposure conditions. The upregulation of these genes may be involved in the mechanism by which these fumigants inhibit the decay caused by pathogenic fungi.
