Abstract

The invention discloses development and application of a purple gene marker for controlling capsicum green fruit. The application of a substance for detecting the genotype of the SNP-78-708 locus of acapsicum genome in identifying or assisting in identifying the color of the capsicum green fruit or the application of the substance for detecting the genotype of the SNP-78-708 locus of the capsicumgenome in preparing a product for identifying or assisting in identifying the color of the capsicum green fruit are provided. The SNP lotus is the 193360134 lotus of the chromosome 10 of the capsicumgenome. Experiments prove that a molecular marker is found at about 37.8.3 Mb downstream the chromosome 10 A gene, and dCAPs marker CAPS-78-708 is designed according to the molecular marker, and thecolor of the capsicum green fruit can be detected.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and in particular relates to the development and application of a gene marker for regulating the purple color of capsicum green fruit. Background technique

[0002] Anthocyanins are an important class of water-soluble secondary metabolites that widely exist in nature, mainly distributed in the flowers and fruits of crops, but also commonly found in the leaves, stems and seeds of crops. Pepper (Capsicum annuum L.) is an important agricultural crop in the world and is a good source of vitamins, carotenoids and flavonoids. The chlorophyll and carotenoids in the pepper fruit make it appear green, yellow, orange and red fruits. Among the cultivated capsicum germplasm resources, there are several purple fruit genotypes, which may be an important source of anthocyanins. However, the purple pigmentation appears only in the unripe fruit.
