气候变化为粮食生产、生态系统的稳定性带来了重要的挑战。在极端气候变化下,发展适应性物种是作物遗传育种的重要目标之一。作为重要的作物之一,玉米在经历强烈的驯化瓶颈之后,已经丢失了大量的遗传多样性,特别是一些与生物和非生物胁迫相关的位点。在野生种和农家种中寻找玉米驯化过程中丢失的遗传多样性,并将其应用于现代遗传育种中,将为适应性新品种的创制提供新的契机。本文在对大刍草(玉米野生近亲)的发现及分类研究进行介绍之后,进一步总结了大刍草和玉米的性状与基因组差异,并综述了目前基于遗传学、群体遗传学、分子生物学等对大刍草和玉米之间差异遗传机理剖析的进展,多角度表明了大刍草在玉米遗传学研究中的重要性。最后,对未来气候变化下大刍草在玉米育种中的重要性提出了展望。
