doi:10.7668/hbnxb.2014.S1.038

Abstract

Abstract: The aim of this study was to determine the variation of telomerase during the life-span and with sampling position of leaves in different tree species.Therefore,TRAP assay was used to determine telomerase activity in Pinus tabulaeformis, Ginkgo biloba, Catalpa bungei C.A.Mey,and Sophora japonica Linn.The results showed that no significant difference of telomerase activity was found among different ages of trees.But the higher telomerase activitives were found in the top position leaves of Pinus tabulaeformis and Ginkgo biloba.The effect of leaf position on the telomerase activity in Pinus tabulaeformis and Ginkgo biloba was strong and significant.This is the first observation on such a position-related variation in telomerase activity.

Key words: Tree age, Telomere, Telomerase, Leaf position
