B vitamins are a source of coenzymes for a vast array of enzyme reactions, particularly those of metabolism. As metabolism is the basis of decisions that drive maintenance, growth, and development, B vitamin–derived coenzymes are key components that facilitate these processes. For over a century, we have known about these essential compounds and have elucidated their pathways of biosynthesis, repair, salvage, and degradation in numerous organisms. Only now are we beginning to understand their importance for regulatory processes, which are becoming an important topic in plants. Here, I highlight and discuss emerging evidence on how B vitamins are integrated into vital processes, from energy generation and nutrition to gene expression, and thereby contribute to the coordination of growth and developmental programs, particularly those that concern maintenance of a stable state, which is the foundational tenet of plant homeostasis.Expected final online publication date for the Annual Review of Plant Biology, Volume 75 is May 2024.

B 族维生素：其对植物稳态重要性的最新进展

B 族维生素是多种酶反应（尤其是新陈代谢反应）的辅酶来源。由于新陈代谢是驱动维持、生​​长和发育的决策的基础，B 族维生素衍生的辅酶是促进这些过程的关键成分。一个多世纪以来，我们已经了解了这些必需化合物，并阐明了它们在许多生物体中的生物合成、修复、回收和降解途径。直到现在，我们才开始了解它们对于监管流程的重要性，监管流程正在成为工厂的一个重要话题。在此，我重点介绍并讨论了 B 族维生素如何融入从能量产生和营养到基因表达的重要过程中的新证据，从而有助于协调生长和发育计划，特别是那些涉及维持稳定状态的计划，是植物稳态的基本原则。《植物生物学年度评论》第 75 卷的预计最终在线出版日期为 2024 年 5 月。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计。
