This paper uses model plant Arabidopsis thaliana as material,analyzing its methylation variations after cryopreservation treetment and heavy metals cadmium stress seprately.It was used methylation-sensitive amplified polymorphism(MSAP)technique to analyze the genomic DNA methylation.The main findings are as follows:
1.The sample survival rates after cryopreservation influnced by the level of seeds germination,if the former is not complete,it had the low survival rate of seedlings after cryopre...
