Signature

Signature identifies clade-specific signature genes within query sequences to enable phylogenetic characterization of metagenomic and genomic datasets.

Key Features:

• Signature Gene Detection: Detects genes unique to and prevalent within specific taxonomic clades to serve as phylogenetic markers.
• Clade Assignment and Visualization: Reports taxonomic clades sharing signature genes with input sequences and generates a color-coded tree of life representation based on shared signature gene counts.

Scientific Applications:

• Phylogenetic and Metagenomic Analysis: Supports taxonomic origin inference and evolutionary characterization of sequence datasets using clade-specific gene markers.

Methodology:

Signature analyzes query sequences to identify genes uniquely associated with defined taxonomic clades, quantifies shared signature genes across taxa, and maps results onto a phylogenetic framework for clade-level assignment.
