SSR molecular marker for salt tolerance of Fraxinus velutina

Abstract

The invention discloses an SSR molecular marker for the salt tolerance of Fraxinus velutina. Primers of loci of the SSR molecular marker for the salt tolerance of Fraxinus velutina include the primer S78 and the primer S95. The SSR molecular marker is expected to become a standard primer for identifying the salt tolerance of Fraxinus, and the accurate molecular marker is provided for rapid identification of salt-tolerant germplasm of Fraxinus and salt-tolerant breeding of Fraxinus. By means of the SSR molecular marker, the purpose of identifying salt-tolerant Fraxinus and salt-sensitive Fraxinus from the perspective of molecules is achieved, and a reference and a basis are provided for research such as salt tolerance molecular identification of Fraxinus.

Description

technical field [0001] The invention relates to a molecular marker, in particular to a salt-tolerant SSR molecular marker of white wax tomentosa, belonging to the technical field of molecular biology. Background technique [0002] Salt damage is a common abiotic stress for plants in the Yellow River Delta region, and it is one of the main environmental factors affecting plant growth and yield. Therefore, the breeding of new salt-tolerant plant varieties has always been the focus of research at home and abroad. Salt tolerance of plants is a complex quantitative trait involving the coordination of many genes and mechanisms of salt tolerance (Hao Derong et al., 2013). It is very difficult to identify salt-tolerant and salt-sensitive materials by morphological methods, especially to screen salt-tolerant individuals from hybrid progenies of salt-tolerant and salt-sensitive plants, which usually requires physiological assays and salt-tolerance tests, which are time-consuming, lab...
