摘要

生物分子凝聚是指将生物大分子（DNA、RNA、蛋白质）集中到小室中，形成具有独特性质和功能的无膜细胞器或凝聚体。这种无处不在的现象近年来备受关注，因为它在生命系统的发育过程和对环境线索的反应中发挥着多方面的作用。最近的研究发现，生物分子缩合在调节植物从无性生殖向生殖生长过渡的过程中发挥着至关重要的作用，这一程序化过程被称为花期过渡，它决定了开花植物的开花时间和花序结构。在这篇 "坦斯利洞察 "中，我们回顾了生物分子缩聚如何整合发育和环境信号，对花的过渡过程进行编程和重编程，从而使开花时间和花序结构多样化的研究进展。

Biomolecular condensation programs floral transition to orchestrate flowering time and inflorescence architecture

Biomolecular condensation involves the concentration of biomolecules (DNA, RNA, proteins) into compartments to form membraneless organelles or condensates with unique properties and functions. This ubiquitous phenomenon has garnered considerable attention in recent years owing to its multifaceted roles in developmental processes and responses to environmental cues in living systems. Recent studies have revealed that biomolecular condensation plays essential roles in regulating the transition of plants from vegetative to reproductive growth, a programmed process known as floral transition that determines flowering time and inflorescence architecture in flowering plants. In this Tansley insight, we review advances in how biomolecular condensation integrates developmental and environmental signals to program and reprogram the floral transition thus diversifies flowering time and inflorescence architecture.

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
