Molecular marker closely linked with peanut ethylene insensitivity and salt tolerance related characters and application

Abstract

The invention discloses a molecular marker closely linked with peanut ethylene insensitivity and salt tolerance related characters and application, and belongs to the technical field of plant molecular genetics and molecular breeding. The molecular marker closely linked with the ethylene insensitivity and salt tolerance related characters of the peanuts is an InDel marker Arahy01063 and / or Arahy01102, and the molecular marker is an InDel marker Arahy01063 and / or Arahy01102. The molecular marker provided by the invention can realize rapid detection of ethylene insensitivity and salt tolerance of peanuts, eliminates the influence of the environment, and has important application value in peanut molecular breeding and acceleration of the cultivation process of peanut salt-tolerant varieties.

Description

technical field [0001] The invention belongs to the technical field of plant molecular genetics and molecular breeding, and specifically relates to a molecular marker closely linked with peanut ethylene insensitivity and salt tolerance related traits and its application. Background technique [0002] Peanut (Arachis hypogaea L.), as an important oil crop and economic crop in the world, plays an important role in combating malnutrition and ensuring food security. In recent years, domestic and foreign scholars have made breakthroughs in the cultivation of new varieties of peanuts, the utilization of wild germplasm resources, and molecular design breeding. huge contribution. Salt stress will inhibit the growth of peanuts, cause the plants to wilt, reduce the yield, and at the same time make the quality of the pods deteriorate, and the commercial value will be significantly reduced. With the increasing soil salinization, creating new salt-tolerant peanut germplasm, mining salt...

AI Technical Summary

Problems solved by technology

A series of members of ethylene from receptors to downstream regulatory transcription factors are involved in the response process of plants to salt stress to varying degrees, and the ethylene induced by salt stress in turn positively regulates the response of plants to salt stress, but ethylene improves the salt tolerance of plants Sexual signal transduction pathways and specific mechanisms are still unclear (Yu Yanwen et al., 2013)

However, there is no report on the relationship between ethylene and peanut salt tolerance.
