These data suggest that high temperature can stimulate peroxidase activity thus anthocyanin degradation in ripening grape berries.Īrcher E, Strauss HE (1989) Effect of shading on the performance of Vitis vinifera L. Overexpression of VviPrx31 decreased anthocyanin contents in Petunia hybrida petals under heat stress condition. This suggests that the low anthocyanin content of HT berries reflects the combined impact of reduced biosynthesis and increased degradation, particularly the direct role of peroxidases in anthocyanin catabolism. Under HT conditions, the biosynthesis of anthocyanins was suppressed at both the transcriptional and enzymatic levels, but peroxidase activity was higher.
The anthocyanin concentration at harvest was much lower in HT berries than LT berries although their profile was similar under both conditions. The low temperature (LT) conditions featured average and maximum daily air temperatures of 20 and 29 ☌, respectively, whereas the corresponding high temperature (HT) conditions were 22 and 36 ☌, respectively. Potted uniform plants of Sangiovese were kept from veraison to harvest, in two plastic greenhouses with different temperature conditions.

Here we studied the effects of two different temperature regimes, representing actual Sangiovese ( Vitis vinifera L.) viticulture regions, on the accumulation of mRNAs and enzymes controlling berry skin anthocyanins. Anthocyanin levels decline in some red grape berry varieties ripened under high-temperature conditions, but the underlying mechanism is not yet clear.
