doi:10.11983/CBB24049

摘要/Abstract

摘要： 植物在其生命周期中面临多种非生物胁迫，如高温、干旱和盐碱等，这些胁迫对植物的生长发育产生多方面影响。全球变暖加剧了高温胁迫对玉米等作物的影响，可能导致其生长受阻、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严重影响。植物通过复杂的分子机制响应高温，涉及多个信号传导途径和基因表达调控。通过遗传学、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耐受高温等非生物胁迫的相关基因和位点至关重要。这些研究不仅有助于我们深入理解玉米耐受胁迫的生物学机制，还将为育种家提供关键的分子标记和候选基因资源，进而加快玉米新品种的培育速度。

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

Key words: maize, growth and development, heat stress, thermotolerance
