摘要
Methylation levels of the two populations of Iva xanthifolia Nutt. from Harbin and Daqing areas were determined using methylation-sensitive-amplification-polymorphism (MSAP) method. The results showed that there was no significant difference of the overall level of DNA "CCGG" sites with and without methylation Harbin and Daqing population. The level of fully methylation sites was higher than that of hemi-methylation sites in both the groups of I. xanthifolia, specially the level of fully methylation of Daqing population was about three times more than that of level of hemi-methylation.
