Abstract

Abstract:

Soil salinization poses a severe threat to global food security and ecological environments. Cultivating salt-tolerant crop varieties and enhancing crop salt tolerance can effectively address salinization stress and utilize saline-alkali lands. We elucidate the molecular mechanisms of plant salt tolerance and focus on the cutting-edge technologies in crop salt tolerance breeding, systematically elaborating on the principles and application achievements of technologies such as multi-omics integrated analysis, gene editing, plant growth-promoting rhizobacteria (PGPR) and epigenetic modifications in crop salt tolerance breeding. These advanced technologies provide guidance for crop salt tolerance breeding. Through technological integration and innovation, it may be hold the potential to rapidly and precisely develop new salt-tolerant crop varieties, thereby promoting efficient and sustainable agricultural development in saline-alkali lands.

Key words: crop tolerance, molecular breeding technology, multi-omics integrated analysis, gene editing, plant growth-promoting rhizobacteria, epigenetic modification
