Abstract
This dataset contains a spreadsheet with sample information (herbarium voucher, GenBank accession number, occurrence in Brazilian biomes), an alignment of 430 terminals and 2730 bp (plastid trnD-trnT region), and a phylogenetic tree generated with IQ-Tree (maximum likelihood with bootstrap support) in format newick and pdf. This data refers to the paper "Continued progress in Mimosa (Leguminosae): Tackling the systematics of a big genus in the Brazilian flora" published in Systematic Botany.
Dataset DOI: 10.5061/dryad.rbnzs7hqd
Description of the data and file structure
Sequence data from the plastid trnD–trnT region were downloaded from GenBank and aligned into a dataset comprising 430 terminals, representing a broad range of taxa within Mimosa. Phylogenetic inference was conducted using IQ-TREE (Trifinopoulos et al. 2016) under a maximum likelihood framework with default parameters. Node support was estimated using ultrafast bootstrap support with 1000 replicates.
