Effect of low cost physical technologies on fungal decay and expression of pathogenesis-related-protein genes in table grapes stored at low temperature. The effect of high levels of CO2 and low temperature was studied with regard to its effectiveness on controlling natural decay in table grapes by the induction of specific pathogenesis related proteins (PRs). Full-length cDNAs encoding a class I chitinase and beat-1,3-glucanase were isolated from fruits of Vitis vinifera L. cv. Cardinal. The results indicate that this short-term high CO2 treatment had a residual effect reducing decay incidence of fruits stored at 0ºC. The expression of class I chitinase and beta-1,3-glucanase genes is not enhanced in CO2-treated grapes which control total fungal decay, suggesting that its efficacy is not mediated by induction of these PR genes.The abundance of the beta-1,3-glucanase transcript increased sharply when grapes were exposed to low temperature independently of fungal attack. We have characterised recombinant beta-1,3-glucanase to further examine it role and contributions to cold tolerance in grapes. Log in to add this item to your schedule
