摘要

温带多年生植物的春季再生依赖于更新芽,更新芽是嫩枝生长周期的关键组成部分。然而,我们对这些更新芽几乎一无所知,而随着当前气候变化的加剧,这一点变得更加迫切。现有研究大多集中在易于研究的木本植物地上芽上,其形态在很大程度上与防冻有关。目前还不清楚这些发现在多大程度上也适用于草本植物。因此,我们研究了 379 种温带草本植物的保护性特征和冬季更新芽的前期形成,并测试了这些特征在系统发育中的分布情况以及与其他芽库和整个植物特征的关系。我们发现了一个主要的梯度,从土壤深处与较大的地下贮藏器官相关的少量、大型、高度预成形、鳞片覆盖的芽,到土壤表面附近的小型、大量、较少预成形和裸露的芽。温带草本植物的地下更新芽表现出几种不同的越冬和春季再生策略,这些策略可能会影响它们对冬季和早春条件变化的反应。更新芽的特性不仅受到防冻的驱动,还受到保护顶端分生组织免受土壤中机械干扰的驱动。

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.
