Seasonal bud dormancy in perennial woody plants is a crucial and intricate process that is vital for the survival and development of plants. Over the past few decades, significant advancements have been made in understanding many features of bud dormancy, particularly in model species, where certain molecular mechanisms underlying this process have been elucidated. We provide an overview of recent molecular progress in understanding bud dormancy in trees, with a specific emphasis on the integration of common signaling and molecular mechanisms identified across different tree species. Additionally, we address some challenges that have emerged from our current understanding of bud dormancy and offer insights for future studies.
树木芽休眠是多年生木本植物中一个至关重要且复杂的过程，对植物的生存和发育至关重要。在过去的几十年中，人们在理解芽休眠的许多特征方面取得了重大进展，特别是在模式物种中，阐明了该过程的某些分子机制。我们概述了近年来在理解树木芽休眠方面的分子进展，特别强调了不同树种中共同的信号和分子机制的整合。此外，我们还讨论了当前对芽休眠理解中出现的一些挑战，并为未来的研究提供了一些见解。
