Chloroplast Genomic Insights Coupled with Morphological and Palynological Evidence Uncover Adaptive Divergence and Taxonomic Boundaries in Impatiens L.

This dataset includes experimental data, images, and supplementary materials for six Impatiens species, covering sample collection locations, morphological traits, pollen micromorphology, and habitat maps. Chloroplast genome data for 18-25 species (from NCBI) are provided for phylogenetic analyses, including genome structures, gene lists, GC content, codon usage, nucleotide diversity (Pi), and SSR/INE distributions across LSC, SSC, and IR regions. Statistical plots of morphological traits and SEM images of pollen are included, along with phylogenetic trees (ML and BI) integrating morphological and pollen traits. The dataset supports morphological, palynological, genomic, and evolutionary studies.

本数据集包含6种凤仙花属（Impatiens）植物的实验数据、图像及补充材料，涵盖样本采集地、形态性状、花粉显微形态与生境分布图。此外，还提供了来自NCBI的18至25个物种的叶绿体基因组数据，用于系统发育分析，内容包括基因组结构、基因列表、GC含量、密码子使用偏好、核苷酸多样性（Pi）以及大单拷贝区（LSC）、小单拷贝区（SSC）和反向重复区（IR）内的简单序列重复（Simple Sequence Repeat，SSR）/INE分布特征。数据集包含形态性状统计绘图、花粉扫描电子显微镜（Scanning Electron Microscope，SEM）图像，以及整合了形态性状与花粉性状的系统发育树（涵盖最大似然法（Maximum Likelihood，ML）与贝叶斯推断法（Bayesian Inference，BI）两种构建方式）。本数据集可支撑形态学、孢粉学、基因组学及进化生物学相关研究。
