Abstract
We designed amplification primers RTetr1 and RTetr2 in order to clarify the relationship between ethylene biosynthesis and receptor ETR1,and find out ethylene transduction and function process during peach senescence. The Baifeng peach cultivar (Amygdalus persica L.) was used to investigate the effects of temperature and GA3 on ethylene biosynthesis and expression of ethylene receptor homologous gene APETR1 during fruit senescence. It was found that ethylene production was reduced by cold storage and cold storage+GA3 treatments. And the latter treatment also delayed the release fastigium. RT-PCR analysis of total cDNA indicated that expression of ETR1 homologous gene modified by cold storage and GA3 treatment had a positive expression mode in ethylene transduction,with the enhancement of fruit ethylene biosynthesis and increasing level of ETR1.
