Abstract

The invention discloses a method for asexual breeding of Populus euphratica based on a gene regulation network, the method comprising: constructing a population of Populus euphratica; performing explant culture according to the positioning population of Populus euphratica, and obtaining the phenotype of rooting ability of Populus euphratica during the cultivation process data, transcriptomics data, proteomics data and metabolomics data; according to the phenotype data, transcriptomics data, proteomics data and metabolomics data of P. pQTL and mQTL; construct the gene regulatory network of Populus euphratica rooting process based on the QTL, eQTL, pQTL and mQTL of the rooting ability of Populus euphratica, and locate the quantitative trait loci nQTL of the rooting ability network of Populus euphratica according to the gene regulatory network; conduct the cloning of Populus euphratica based on the nQTL of the rooting ability of Populus euphratica breeding. The method of the embodiment of the present invention can effectively screen individual Populus euphratica plants with strong rooting ability, increase the reproduction rate of Populus euphratica, and greatly promote the breeding of stress-resistant clones of Populus euphratica.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a method for asexual breeding of Populus euphratica based on a gene regulation network. Background technique [0002] Known as the "hero tree", Populus euphratica is the only tree species that is salt-, cold-, drought-, and wind-sand-resistant distributed in the desert areas of northwest my country. However, due to the serious separation of traits of Populus euphratica seedlings, it is not conducive to screening out excellent individual plants of Populus euphratica. Therefore, in order to overcome the shortcoming of the serious separation of characters of Populus euphratica, currently Populus euphratica is mainly bred through asexual reproduction. However, the rooting ability of Populus euphratica is relatively poor, and the cutting propagation is very difficult due to the low rooting rate when cutting. Therefore, solving the rooting problem of Populus euphratica has become a ...
