WebCVTree4: Phylogenetic and Taxonomic Study Platform for Prokaryotes base on Whole Genomes

Area of Science:

• Genomics
• Bioinformatics
• Evolutionary Biology

Background:

• Whole-genome sequencing data is crucial for understanding species phylogeny and taxonomy.
• Alignment-free methods offer efficient analysis of large genomic datasets.
• Continuous development of the CVTree web service since 2004 has led to significant upgrades.

Purpose of the Study:

• To introduce WebCVTree4, an enhanced platform for whole-genome-based phylogenetic and taxonomic inference.
• To enable the reconstruction of large-scale phylogenetic trees (tens of thousands of species).
• To facilitate the integration of phylogenetic data with established taxonomic systems.

Main Methods:

• Utilizes an alignment-free methodology for phylogenetic reconstruction.
• Features an updated genomic database and optimized core algorithms.
• Incorporates a novel algorithm for comparing phylogenetic trees with taxonomic systems.
• Provides an interactive web interface with dynamic tree layout adjustments and export options.

Main Results:

• WebCVTree4 supports online phylogenetic reconstruction for tens of thousands of species.
• The platform enables rapid tree rooting, taxonomic annotation, and topology comparison.
• Enhanced visualization tools allow for high-quality export of phylogenetic tree figures.
• Facilitates comprehensive comparative analyses integrating phylogenetics and taxonomy.

Conclusions:

• WebCVTree4 represents a significant advancement in whole-genome-based phylogenetic and taxonomic analysis.
• The platform is a valuable resource for microbial evolution and taxonomy research.
• WebCVTree4 provides an efficient web-based solution for large-scale phylogenomic studies.
