2026-05-06 Datasets for Phylogenetic analysis of Ardisia and its relatives. doi:10.57760/sciencedb.35368 en This dataset comprises three main types of genomic data designed to resolve the phylogenetic relationships and evolutionary history of the genus Ardisia and its closely related taxa. The data integration strategy aims to provide robust topological comparison from both organellar and nuclear perspectives. The dataset includes:a. Concatenated Plastid Gene Alignment:A comprehensive alignment consisting of 80 protein-coding genes (CDS) extracted from the 134 chloroplast genomes. This dataset is used to evaluate the maternal evolutionary lineage and examine the impact of different partitioning strategies (e.g., no-partitioning, partitioning by gene, and partitioning by codon position) on tree topology.b. Nuclear Ribosomal DNA (nrDNA) Alignment:A complete nrDNA dataset (including ITS, 18S, 5.8S, and 26S regions) providing a nuclear genomic perspective. c. Whole-Genome SNP Alignment:A Single Nucleotide Polymorphism (SNP) dataset produced by the WASTER pipeline. This alignment leverages whole-genome data to capture fine-scale genetic variations, offering maximum power for species tree estimation.
