The Caspase 3-like protease activity and TaeMCAⅡ gene expression during the process of programmed cell death(PCD)in wheat(Hua 8)endosperm under normal and waterlogging treatments were studied in this paper.The results indicated that,under normal treatments,the activity of Caspase 3-like protease was higher in the previous phase of endosperm PCD(12DAF),and the protease was mainly located in amyloplasts of wheat endosperm cells,while the expression of TaeMCAⅡ gene was similar during endosperm PCD.The Caspase ...
