Data for: Mycorrhizas drive the evolution of plant adaptation to drought

Plant adaptation to drought facilitates major ecological transitions, and will likely play a vital role under looming climate change. Mycorrhizas, i.e. strategic associations between plant roots and soil-borne symbiotic fungi, can exert strong influence on the tolerance to drought of extant plants. Here, I show how mycorrhizal strategy and drought adaptation have been shaping one another throughout the course of plant evolution. To characterize the evolutions of both plant characters, I applied a phylogenetic comparative method using data of 1,638 extant species globally distributed. The detected correlated evolution unveiled gains and losses of drought tolerance occurring at faster rates in lineages with ecto- or ericoid mycorrhizas, which were on average about 15 and 300 times faster than in lineages with the arbuscular mycorrhizal and naked root (non-mycorrhizal alone or with facultatively arbuscular mycorrhizal) strategy, respectively. My study suggests that mycorrhizas can play a k..., , This dataset contains the Supplementary Data 1, Supplementary Data 2, Supplementary Data 3, Supplementary Data 4, and Supplementary Note 1 of the article (https://doi.org/10.1038/s42003-023-04722-4).
Supplementary Data 1: includes the files of the phylogenetic trees (in RDS format, which can be open in R) and data frames (in csv format) containing data on plant mycorrhizal strategy and drought adaptation assignments according to dataset v1 to v6. These dataset versions were assembled as described in the Methods of the article. These files and data frames were uploaded as supplemental information to Zenodo and can be found at https://doi.org/10.5281/zenodo.7670985.
Supplementary Data 2: provides a data frame with 112,276 geographical occurrences (latitude and longitude) for 1,066 of the species included in the analysis. These geographical occurrences were originally obtained from a Global Biodiversity Information Facility (occurrence data download https://doi.org/10.15468/dl.5mab9f) and ...

植物对干旱的适应促进了重大生态转型，且在日益严峻的气候变化背景下可能发挥关键作用。菌根（Mycorrhizas），即植物根系与土壤共生真菌之间的策略性关联，可对现存植物的干旱耐受性产生显著影响。本文揭示了菌根策略与干旱适应在植物进化历程中如何相互塑造。为刻画这两种植物性状的演化规律，我采用系统发育比较方法（phylogenetic comparative method），分析了全球分布的1638种现存物种的数据。检测到的关联演化表明，具有外生菌根（ecto-mycorrhizas）或欧石楠型菌根（ericoid mycorrhizas）的谱系中，干旱耐受性的获得与丧失速率更快，分别比具有丛枝菌根（arbuscular mycorrhizal）和裸根（仅非菌根或兼性丛枝菌根）策略的谱系快约15倍和300倍。本研究表明，菌根可发挥关键... 本数据集包含该文章（https://doi.org/10.1038/s42003-023-04722-4）的补充数据1、补充数据2、补充数据3、补充数据4及补充说明1。补充数据1：包含系统发育树（phylogenetic trees）文件（RDS格式，可在R中打开）和数据框（csv格式），其中记录了根据数据集v1至v6划分的植物菌根策略与干旱适应类型。这些数据集版本的组装方式详见文章方法部分。上述文件与数据框已作为补充信息上传至Zenodo，可通过https://doi.org/10.5281/zenodo.7670985获取。补充数据2：提供了一个数据框，包含分析中1066个物种的112276条地理分布记录（纬度与经度）。这些地理分布记录最初来自全球生物多样性信息设施（Global Biodiversity Information Facility）（分布数据下载链接：https://doi.org/10.15468/dl.5mab9f），且...
