摘要: 植物在其生命周期中面临多种非生物胁迫, 如高温、干旱和盐碱, 这些胁迫对植物的生长发育产生多种影响。全球变暖加剧了高温胁迫对玉米(Zea mays)等作物的影响, 可能导致其生长受阻和生殖能力下降。玉米作为重要的农作物, 其产量和品质受高温胁迫影响严重。植物通过复杂的分子机制响应高温, 涉及多个信号转导途径和基因表达调控。利用遗传学、基因组学、多组学分析以及高通量表型分析等前沿技术, 深入挖掘和解析玉米基因组中非生物胁迫耐受性(包括热胁迫)的相关基因和位点至关重要。这些研究不仅有助于深入理解玉米耐受胁迫的生物学机制, 而且为加快玉米新品种培育提供了关键的分子标记和候选基因资源。

Abstract: Plants encounter various abiotic stresses throughout their lifecycle, including heat, drought, and salt stress, all of which have diverse impacts on their growth and development. Global warming has exacerbated the impact of heat stress on crops such as maize, potentially leading to growth retardation and reduced reproductive capacity. As an important staple crop, the yield and quality of maize are severely compromised by heat stress. Plants respond to heat stress through complex molecular mechanisms involving multiple signal transduction pathways and the regulation of gene expression. It is crucial to use advanced techniques such as genetics, genomics, multi-omics analysis, and high-throughput phenotyping to extensively explore and analyze the genes and loci associated to abiotic stress tolerance, including heat stress, in the maize genome. These studies not only deepen our understanding of the biological mechanisms underlying maize stress tolerance but also provide valuable molecular markers and candidate gene resources for breeders to accelerate the development of new maize varieties.
