| Abstract: | Expression of ascorbate peroxidase(APX) gene in different tea cultivars and in the withering process of tea leaves was analyzed by fluorescence quantitative polymerase chain reaction(qPCR) technology.It was showed that the expression amounts of APX gene in different tea cultivars were significantly different.The changing range of relative expression amounts was from 0.65 to 5.69.The ranking list of relative expression amounts of APX gene in 6 tea cultivars was: Maoxie>Fuyun 6>Rougui>Fudingdabaicha>Huangdan>Tieguanyin.In the process of tea withering,the expression amounts of APX gene increased at first,followed by a decline,and then increased again,finally decreased,and the change range of relative expression amounts was from 0.02 to 7.46;at the same time,the expression of APX gene was affected by the treatment of withering technique. |
