In flowering plants, male reproductive development is highly susceptible to heat stress. In this mini-review, we summarized different anomalies in tapetum, microspores, and pollen grains during anther development under heat stress. We then discussed how epigenetic control, particularly DNA methylation, is employed to cope with heat stress in male reproduction. Further understanding of epigenetic mechanisms by which plants manage heat stress during male reproduction will provide new genetic engineering and molecular breeding tools for generating heat-resistant crops.
在开花植物中，雄性生殖发育对热胁迫高度敏感。在这篇小型综述中，我们总结了热胁迫下花药发育过程中绒毡层、小孢子和花粉粒的不同异常情况。然后，我们讨论了表观遗传调控，特别是DNA甲基化，如何用于应对雄性生殖中的热胁迫。进一步了解植物在雄性生殖过程中应对热胁迫的表观遗传机制，将为培育耐热作物提供新的基因工程和分子育种工具。
