Supplementary files for "Which morphological traits can be used to reconstruct genome size in fossil plants? Assessing sporomorph size and stomatal guard cell length as paleo-genome size proxies"

R code and data files to recreate all analyses in the paper, as well as Supplementary Figures 1 - 8 (file Jardine_GenomeSize_suppFigs.pdf), and Supplementary Tables 1 - 9 (file Jardine_GenomeSize_suppTables.xlsx).Data files comprise:Pollen and stomatal guard cell length data from plants sampled from the University of Münster Botanical Garden (MBG), plus associated genome size information.Pore length data for MBG plants with sunken stomata, and guard cell length and pore length data for calibration taxa (used to estimate guard cell length for sunken stomata taxa).Guard cell length and genome size data from Lomax et al. (2014) New Phytologist, for independent validation of the genome size-guard cell length relationship.Literature compilations of fern spore size, Pinaceae pollen size, and Poaceae pollen size, plus associated genome size information.To run the R code, put all files into one folder, and set this as the working directory in the R session.<br><br><br>

本数据集包含可复现论文所有分析的R代码与数据文件，以及补充图1至8（文件名为Jardine_GenomeSize_suppFigs.pdf）与补充表1至9（文件名为Jardine_GenomeSize_suppTables.xlsx）。数据文件包含以下内容：采自明斯特大学植物园（University of Münster Botanical Garden, MBG）的植物花粉与气孔保卫细胞长度数据，以及配套的基因组大小信息；含下陷气孔的MBG植物的气孔孔道长度数据，以及校准类群的保卫细胞长度与孔道长度数据（该类群数据用于估测下陷气孔类群的保卫细胞长度）；取自Lomax等人2014年发表于《新植物学家》（New Phytologist）的研究的保卫细胞长度与基因组大小数据，用于独立验证基因组大小与保卫细胞长度的相关性；蕨类孢子大小、松科（Pinaceae）花粉大小以及禾本科（Poaceae）花粉大小的文献汇编数据，以及配套的基因组大小信息。若需运行R代码，请将所有文件置于同一文件夹，并将该文件夹设置为R会话的工作目录。
