Against the backdrop of the continuous expansion of salinized soils worldwide, the development of salt-tolerant crops has become a key strategy to enhance agricultural stability and sustainability. This study aims to elucidate the genetic regulatory mechanisms underlying the uptake of micronutrients such as iron, zinc, and manganese by salt-tolerant crops under saline-alkaline conditions, and systematically evaluates the roles of key functional genes in micronutrient utilization. Through the integration of big data and multi-omics analyses—including genomics, transcriptomics, and epigenetics—the physiological response patterns of crops under various salinity conditions and their underlying genetic networks were revealed. In parallel, the synergistic effects of traditional breeding approaches and advanced gene editing technologies in improving salt-tolerant crop varieties are discussed, along with strategies for leveraging intelligent algorithms to optimize breeding parameters and construct integrated, precision-oriented breeding models. The findings offer new insights into the molecular basis of micronutrient uptake in salt-tolerant crops and provide theoretical and technical support for the sustainable development of agriculture on saline-alkaline soils globally.
