Abstract

The invention discloses a method for screening molecular markers relevant to few-root duckweed leaf growth. The method comprises the steps of clone body culture, genome DNA (deoxyribonucleic acid) extraction, microsatellite primer design, PCR (polymerase chain reaction) amplification and data statistics and analysis. The method has the beneficial effects that the DNA sequences of a great amount of few-root duckweed marked by the microsatellite primers can be fast obtained; the microsatellite mark detection speed is high; the polymorphic map of the few-root duckweed Sp10, Sp14, Sp42, Sp47, Sp51, Sp52 and Sp53 genetic marker loca showing the high-degree genetic variation can be fast obtained. The leaf length and the leaf width of the few-root duckweed are obviously relevant to Sp10, Sp14, Sp42, Sp47, Sp51, Sp52 and Sp53 (P of the Sp51 site is lower than 0.05, and P of other sites is smaller than 0.001). The influence of the genotype differences on the duckweed growth and pollutant purification capability can be known; the wastewater biological treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of DNA molecular markers, in particular to a method for screening molecular markers related to the growth of leaves of P. Background technique [0002] In the natural environment, P. spp. basically reproduces asexually. When the environmental conditions are suitable, one generation can be cloned in 2 days. The genetic diversity of the population is low. [0003] The prior art provides a variety of detection methods for satellite markers, for example, Chinese Invention Authorized Patent Document A Rapid Detection Method for Microsatellite Markers in Rust Spotted Catfish Authorized Announcement No. CN 103305611 B This invention relates to a rapid detection method for rust spotter microsatellite markers , including: (1) the extraction of genomic DNA of P. rufosa; (2) obtaining the gene sequence containing microsatellite repeats according to the functional gene sequence of P. rufosa in the GeneBank database; (3)...
