Study on the Role of Caspase-3 at Longan Pulp Autolysis
Pulp quality changes of longan cv.Shixia stored at 3-5℃ were investigated and the activity of caspase-3 and autolysis index were determined during storage, and the roles of caspase-3 in longan pulp-autolysis and programmed cell death (PCD) were discussed.During cold storage stage of longan fruit,activity of caspase-3 fluctuated. At the beginning of storage,caspase-3 activity rose before the occurrence of pulp-autolysis. It increased quickly with enhanced pulp autolysis. The activity of caspase-3 in the autolytic pulp was significantly higher than that in the non-autolyzed pulp.The results indicated that caspase-3 may take part in the initiation and enhancement of the pulp autolysis,which maybe a result of PCD.
