摘要

植物可以对其基因组进行编程和重编程,从而产生遗传变异和表观遗传修饰,导致表型的可塑性。虽然基因变化的后果可以理解,但表观遗传变异的跨代遗传基础却难以捉摸。本综述探讨了在植物进化、作物驯化和现代育种过程中,外部(环境)和内部(基因组)因素对表观遗传记忆的建立和维持所起的作用。DNA 甲基化和染色质修饰的动态和普遍变化为表观遗传变异提供了多种可能的跨代遗传途径。阐明和利用表观遗传将有助于我们开发创新的育种策略和生物技术工具,以提高作物产量和抵御环境挑战的能力。除植物外,包括人类在内的有性生殖生物也共享表观遗传学原理,这与医学和公共卫生息息相关。

Transgenerational epigenetic inheritance during plant evolution and breeding.

Plants can program and reprogram their genomes to create genetic variation and epigenetic modifications, leading to phenotypic plasticity. Although consequences of genetic changes are comprehensible, the basis for transgenerational inheritance of epigenetic variation is elusive. This review addresses contributions of external (environmental) and internal (genomic) factors to the establishment and maintenance of epigenetic memory during plant evolution, crop domestication, and modern breeding. Dynamic and pervasive changes in DNA methylation and chromatin modifications provide a diverse repertoire of epigenetic variation potentially for transgenerational inheritance. Elucidating and harnessing epigenetic inheritance will help us develop innovative breeding strategies and biotechnological tools to improve crop yield and resilience in the face of environmental challenges. Beyond plants, epigenetic principles are shared across sexually reproducing organisms including humans with relevance to medicine and public health.

期刊介绍: Trends in Plant Science is the primary monthly review journal in plant science, encompassing a wide range from molecular biology to ecology. It offers concise and accessible reviews and opinions on fundamental plant science topics, providing quick insights into current thinking and developments in plant biology. Geared towards researchers, students, and teachers, the articles are authoritative, authored by both established leaders in the field and emerging talents.
