Abstract

Trees cover vast areas of the Earth’s landmasses. They mitigate erosion, capture carbon dioxide, produce oxygen and support biodiversity, and also are a source of food, raw materials and energy for human populations. Understanding the growth cycles of trees is fundamental for many areas of research. Trees, like most other organisms, have evolved a circadian clock to synchronize their growth and development with the daily and seasonal cycles of the environment. These regular changes in light, daylength and temperature are perceived via a range of dedicated receptors and cause resetting of the circadian clock to local time. This allows anticipation of daily and seasonal fluctuations and enables trees to co-ordinate their metabolism and physiology to ensure vital processes occur at the optimal times. In this review, we explore the current state of knowledge concerning the regulation of growth and seasonal dormancy in trees, using information drawn from model systems such as Populus spp.

随时间生长：探索树木生长的分子机制

 抽象的

树木覆盖了地球陆地的广大地区。它们减轻侵蚀、捕获二氧化碳、产生氧气并支持生物多样性，同时也是人类食物、原材料和能源的来源。了解树木的生长周期是许多研究领域的基础。与大多数其他生物一样，树木已经进化出了生物钟，以使它们的生长和发育与环境的日常和季节周期同步。光、日长和温度的这些规律变化通过一系列专用受体感知，并导致生物钟重置为当地时间。这样可以预测每日和季节性波动，并使树木能够协调其新陈代谢和生理机能，以确保重要过程在最佳时间发生。在这篇综述中，我们利用从杨属植物等模型系统中提取的信息，探讨了有关树木生长和季节性休眠调节的知识现状。
