Global climate change exacerbates the effects of environmental stressors, such as drought, flooding, extreme temperatures, salinity, and alkalinity, on crop growth and grain yield, threatening the sustainability of the food supply. Maize (Zea mays) is one of the most widely cultivated crops and the most abundant grain crop in production worldwide. However, the stability of maize yield is highly dependent on environmental conditions. Recently, great progress has been made in understanding the molecular mechanisms underlying maize responses to environmental stresses and in developing stress-resilient varieties due to advances in high-throughput sequencing technologies, multi-omics analysis platforms, and automated phenotyping facilities. In this review, we summarize recent advances in dissecting the genetic factors and networks that contribute to maize abiotic stress tolerance through diverse strategies. We also discuss future challenges and opportunities for the development of climate-resilient maize varieties.
全球气候变化加剧了干旱、洪涝、极端温度、盐度和碱度等环境胁迫因素对作物生长和粮食产量的影响，威胁到粮食供应的可持续性。玉米（Zea mays）是全球种植最广泛的作物之一，也是产量最丰富的粮食作物。然而，玉米产量的稳定性高度依赖于环境条件。近年来，高通量测序技术、多组学分析平台和自动化表型设施的发展，使得人们对玉米响应环境胁迫的分子机制有了更深入的了解，并开发出了抗逆品种，这方面取得了巨大的进展。在这篇综述中，我们总结了通过多种策略解析遗传因素和网络对玉米非生物胁迫耐受性的贡献的最新进展。我们还讨论了开发具有气候适应性的玉米品种的未来挑战和机遇。
