Abstract

A peony genome DNA molecule marking method is as follows: extracting a peony genomic DNA for enzyme digestion, connecting an enzyme digestion product with a joint DNA; performing PCR amplification of a connection product and a pre amplified primer to obtain a pre amplified product; taking the pre amplified product for PCR amplification with iPBS primer which is selectively amplified by use of an incision enzyme joint to obtain a PCR selectively-amplified product; then taking the PCR selectively-amplified product to add into a dyeing liquid, applying a sample for electrophoresis, after the electrophoresis, silver staining, observing, photographing and analyzing results. The peony genome DNA molecule marking method is a molecule marking technology based on the PCR and enzyme digestion, and has the advantages of simple operation, low cost and strong applicability; designed for the peony genome study technology, a new molecule marking system based on the retrotransposon is developed, and provides a new technological means for researches on genetic differentiation and evolution of germplasm resources of peony.

Description

technical field [0001] The invention relates to a molecular marker method, in particular to a molecular marker method of peony genome DNA. Background technique [0002] peony( Paeonia Suffruticosa Andr.) is Paeoniaceae (Paeoniaceae) genus Paeoniae ( Paeonia L.) Peony group (Sect. Mouton DC.) Deciduous shrub is an important ornamental greening plant and resource plant. Its flowers are beautiful in shape, bright in color and fragrant, and are praised by people of all ages. history. In the long-term cultivation and domestication process of Chinese peony, more than 1,000 cultivars with different petal colors, numbers, flower shapes and leaf shapes have been formed, represented by the Central Plains, Northwest, Jiangnan and Southwest varieties groups, and the cultivation areas are all over the country. everywhere. There are 9 species in the peony group (Hong Deyuan and Pan Kaiyu, 1999; Hong and Pan, 2007), distributed in 9 provinces including Henan, Gansu, Shaanxi, Shan...
