A trait-based root acquisition-defence-decomposition framework in angiosperm tree species

Plants make trade-offs between root resource acquisition and defence ability, for adapting to the complex belowground environment. This includes forming partnerships with different types of root associating microorganisms, such as arbuscular mycorrhizal and ectomycorrhizal fungi. These trade-offs, by mediating root chemistry, exert legacy effects on nutrient release during decomposition, which may, in turn, affect the ability of new roots to re-acquire resources, thereby generating a feedback loop. However, the linkages at the basis of this potential feedback loop remain largely unquantified. Here, we propose a trait-based root ‘acquisition-defence-decomposition’ conceptual framework and test the strength of relevant linkages across 90 angiosperm tree species. We show that, at the plant species level, the root-fungal symbiosis gradient within the root economics space, root chemical defence (condensed tannins), and root decomposition rate are closely linked, providing support to this fra..., , , # Data and Code for the article \"A trait-based root acquisition-defence-decomposition framework in angiosperm tree species\" --- We have submitted our raw and processed trait data (**Data_Root_traits.xlsx**), R script supporting the data analysis of this study (**2024ADD_Rcode.R**), and processed data used for R script ( **90Treedata.xlsx** ; **PCAdata.xlsx**). ## Descriptions ### **Data\_Root traits.xlsx** * *1_Notes and Variable List*: The Variable List and relevant notes for this dataset. * *2_Species information*: Information on 90 angiosperm tree species used in this study, including site, mycorrhizal type, taxonomic information (species, genus, family, order, superorder), and forested biome. * *3_Root traits (mean+se)*: The species name (Species) and the species mean trait values (Trait) and corresponding standard errors (Trait-se). * *4_Raw and Processed (90speceis)*: Mycorrhizal type (Mycorrhizal), Site, the species name (Species), species mean trait values (Trait), For the ...植物为适应复杂的地下生境，会在根系资源获取与防御能力之间形成权衡策略，其中包括与不同类型的根系共生微生物建立伙伴关系，例如丛枝菌根（arbuscular mycorrhizal）真菌与外生菌根（ectomycorrhizal）真菌。这类权衡通过调控根系化学组成，对分解过程中的养分释放产生遗留效应，进而可能影响新根系重新获取资源的能力，由此形成一个反馈循环。然而，这一潜在反馈循环背后的关联机制仍未得到充分量化。本研究提出了基于性状的根系“获取-防御-分解”概念框架，并针对90种被子植物树种检验了相关关联的强度。研究结果表明，在植物物种水平上，根经济空间（root economics space）内的根-真菌共生梯度、根系化学防御物质（缩合单宁（condensed tannins））以及根系分解速率三者之间存在紧密关联，为该框架提供了实证支持…… # 题为《被子植物树种中基于性状的根系获取-防御-分解框架》的论文配套数据与代码 --- 我们已提交原始与处理后的性状数据集（**Data_Root_traits.xlsx**）、支撑本研究数据分析的R脚本（**2024ADD_Rcode.R**），以及用于该R脚本分析的处理后数据集（**90Treedata.xlsx**；**PCAdata.xlsx**）。 ## 数据说明 ### **Data_Root traits.xlsx** * *1_Notes and Variable List*：本数据集的变量列表与相关说明 * *2_Species information*：本研究所用90种被子植物树种的物种信息，包含采样位点、菌根类型、分类学信息（物种、属、科、目、总目）以及森林生物群区类型 * *3_Root traits (mean+se)*：物种名称（Species）、物种平均性状值（Trait）及其对应的标准误（Trait-se） * *4_Raw and Processed (90个物种)*：菌根类型（Mycorrhizal）、采样位点（Site）、物种名称（Species）、物种平均性状值（Trait），详见后文
