Soybean is an ancient crop domesticated from wild soybean ( Sied. & Zucc) in East Asia 6,000-9,000 years ago and has been widely grown as human food and livestock feed in China, Korea, Japan, and the rest of the world since. Global climate change has led to a series of challenges in soybean cultivation and breeding. With the development of high-throughput genomic sequencing technologies, genomic information on soybeans is now more readily available and can be useful for molecular breeding. However, epigenetic regulations on crop development are still largely unexplored. In this review, we summarized the recent discoveries in the regulatory mechanisms underlying soybean adaptations to biotic and abiotic stresses, particularly with respect to histone modifications and microRNAs (miRNAs). Finally, we discussed the potential applications of this knowledge on histone modifications and miRNAs in soybean molecular breeding to improve crop performance in the changing environment.
大豆是一种古老的作物，于6000 - 9000年前在东亚由野生大豆（Sied. & Zucc）驯化而来，自那时起，在中国、韩国、日本及世界其他地区广泛种植，作为人类食物和牲畜饲料。全球气候变化给大豆种植和育种带来了一系列挑战。随着高通量基因组测序技术的发展，现在更容易获得大豆的基因组信息，这对分子育种很有用。然而，作物发育的表观遗传调控仍在很大程度上未被探索。在这篇综述中，我们总结了大豆适应生物和非生物胁迫的调控机制方面的最新发现，特别是关于组蛋白修饰和微小RNA（miRNA）。最后，我们讨论了这些关于组蛋白修饰和miRNA的知识在大豆分子育种中的潜在应用，以在不断变化的环境中提高作物性能。
