Prunus verecunda chloroplast genome and application thereof

Abstract

The invention discloses a prunus verecunda chloroplast genome for the first time, applies the prunus verecunda chloroplast genome to prunus verecunda system growth research, and analyzes the prunus verecunda growth status in prunus. According to the prunus verecunda chloroplast genome, molecular systematics and phylogeny genomics method are used for establishing phylogenetic relationship of subgenus cerasus species through the chloroplast genome, on the basis, the whole chloroplast genome is taken as a super DNA bar code of subgenus cerasus and used for identifying sakura varieties, technicalsupports for protecting of sakura germplasm resources and species identification are provided, and great significances on breeding typical subgenus cerasus plants, and the evaluation, protection and utilization of genetic diversity are brought.

Description

technical field [0001] The invention belongs to the field of gene technology, and in particular relates to the chloroplast genome of rosa japonica leaf and its application. Background technique [0002] With the development of society, human beings have increasingly urgent needs for the exploration of biodiversity, the rational use of biological resources and the rapid identification of species, and DNA barcoding technology has emerged as the times require. Originally, a DNA barcode referred to a standard DNA sequence used for species identification. The father of DNA barcoding, Hebert et al., successfully identified 200 species of Lepidoptera insects using a fragment of the mitochondrial cytochrome oxidase subunit 1 (cytochromeoxidase I, COI) gene of about 680 bp, and proposed DNA fragments for the first time as distinguishing species. Similar to the concept of DNA barcodes that distinguish goods by barcodes. Each species has a DNA sequence that distinguishes it from othe...
