Abstract

The invention relates to a lycoris spp. plant fluorescence EST-SSR molecular marker and application thereof, and belongs to the technical field of molecular markers. The molecular marker comprises QZ209, QZ155, QZ175 and QZ171. The molecular markers QZ209, QZ155, QZ175 and QZ171 can completely distinguish 16 pieces of lycoris spp. species, wherein a number of polymorphism sites of a primer of theQZ209 is 12, a PIC (polymorphism information content) value is 0.92, and different species of materials of 12 pieces of lycoris spp. can be distinguished through independent application of the QZ209,the QZ209 can be used as an excellent SSR molecular marker to be applied to subsequent classification and identification work of the lycoris spp. species, and a scientific basis is provided for the protection and development of lycoris spp. resources.

Description

technical field

[0001] The invention relates to the technical field of molecular markers, in particular to fluorescent EST-SSR molecular markers of Lycoris plants and applications thereof. Background technique

[0002] Lycoris spp. is an important medicinal and ornamental plant native to my country. Its flower color and flower type are changeable and highly ornamental. The bulbs contain lycoris, galantamine and other alkaloids. , has the important functions of treating myasthenia gravis, senile dementia (Alzheimer's disease, AD), anti-tumor and anti-cancer, etc., and has extremely high economic value. The flowers and leaves of Amaryllis plants have high ornamental value, are prone to variation, and have high interspecific hybridization affinity. It takes 5 years to form a flowering bulb. Only by the appearance shape, color and size of leaves, bulbs and flowers, there will be errors in variety identification and classification, and confusion is likely to occur in sales and pr...
