Abstract

The invention discloses a method for exploring a stress-resistant rapid evolution gene of salix matsudana. The method for exploring the stress-resistant rapid evolution gene of salix matsudana can explore the stress-resistant rapid evolution gene of salix matsudana rapidly, efficiently and accurately, and a rich material basis is provided for salix matsudana genetic breeding to be applied to willow variety breeding with good stress resistance and strong adaptability. The method solves the problems of low mining efficiency and slow speed of traditional willow stress-resistant genes.

Description

technical field [0001] The invention relates to the technical field of forest tree breeding, in particular to a method for discovering stress-resistant rapid evolution genes of willow. Background technique [0002] Willow is a general term for species of Salix.L and Chosenia Nakai in the family Salicaceae. It is a deciduous tree or shrub. It is mainly distributed in the temperate and frigid regions of the northern hemisphere. It is an important source of energy, afforestation and Greening tree species. There are more than 520 species of willows in the world, and Asia is the origin center of willows, among which 257 species are distributed in China. [0003] Willow has good stress resistance, such as salt tolerance, drought tolerance, water and humidity tolerance, and heavy metal stress tolerance, and plays an important role in ecological restoration. [0004] Dry willow (Salix matsudana Koidz) is a tall allotetraploid tree of Salix family Salix, with good stress resistance...
