Repeated evolution of storage root and invasions of alpine biome drove replicated radiations of the megadiverse Corydalis (Papaveraceae) in the Qinghai–Tibet Plateau

The interplay of key innovation and ecological opportunity is commonly recognized to be the catalyst for rapid radiation. Underground storage organs (USOs), as a vital ecological trait, are advantageous for adaptation of plants to extreme environments, but receive less attention compared to aboveground organs. Repeated evolution of various USOs has occurred across the plant tree of life. However, whether repeated occurrences of a USO in different clades of a group can promote its replicated radiations in combination with the invasion of similar environments remains poorly known. Corydalis is a megadiverse genus in Papaveraceae and exhibits remarkable variations in USO morphology and biome occupancy. Here, we first generated a robust phylogeny for Corydalis with wide taxonomic and genomic coverage based on plastome and nuclear ribosomal DNA sequence data. By dating the branching events, reconstructing ancestral ranges, evaluating diversification dynamics, and inferring evolutionary patte..., , , # Data from: Repeated evolution of storage root and invasions of alpine biome drove replicated radiations of the megadiverse Corydalis (Papaveraceae) in the Qinghai–Tibet Plateau

## Description of the data and file structure

## Data.zip

The compressed master directory \"Data.zip\", contains a total of two directories and 85 files:

The first directory \"Alignments\" includes 79 files, which are sequence alignments in NEXUS format for each locus used in phylogenetic analyses. These 79 loci are three nuclear ribosomal DNA regions (nrDNA; 18S, ITS, 26S) and 76 coding regions from plastomes.

The second directory \"Trees\" includes 6 files, which are:

BI-combined.tre: Phylogenetic tree inferred by the combined nrDNA and plastome dataset using Bayesian inference;

BI-nrDNA.tre: Phylogenetic tree inferred by the nrDNA dataset using Bayesian inference;

BI-plastome.tre: Phylogenetic tree inferred by the plastome dataset using Bayesian inference;

ML-combined.tre: Phylogenetic tree inferred by t...,
