Short day-photoperiod triggers and low temperatures increase expression of peroxidase RNA transcripts and basic peroxidase isoenzyme activity in grapevine buds

Only one of the three-reported peroxidase ESTs for Vitis vinifera L. is expressed in the buds of Thompson seedless grapevine. The expressed RNA transcript is triggered by a short-day photoperiod and its abundance is increased by low temperature.
