MGERT

MGERT retrieves protein-coding sequences and flanking regions of mobile genetic elements (MGEs), such as transposons and retrotransposons, from genome assemblies and raw reads to support analysis of their roles in eukaryotic genome plasticity and evolution.

Key Features:

• Protein-coding MGE extraction: Extracts protein-coding sequences of MGEs directly from genome assemblies and raw reads.
• Flanking region retrieval: Retrieves genomic flanking regions alongside MGE coding sequences for context analysis.
• Annotation approaches: Applies both de novo and homology-based annotation methods for MGE detection.
• Targeted MGE classes: Detects and retrieves sequences from transposons and retrotransposons.
• Applicability to eukaryotes: Operates on eukaryotic genome assemblies and raw read datasets without requiring prior knowledge of specific MGE content.
• Automated pipeline: Integrates detection and sequence extraction steps into an automated computational workflow.

Scientific Applications:

• Genome evolution studies: Provide MGE coding sequences and flanking regions for analyses of genome plasticity and evolutionary dynamics.
• Comparative genomics: Enable cross-species surveys of transposon and retrotransposon diversity in eukaryotic genomes.
• Structural variation and regulation: Support investigation of MGE-mediated structural variation and potential impacts on gene regulation.
• Downstream functional and evolutionary analyses: Supply sequence data for functional annotation, phylogenetic inference, and evolutionary reconstruction of MGEs.

Methodology:

MGERT uses de novo and homology-based annotation approaches to detect MGEs in genome assemblies or raw reads and extracts their protein-coding sequences along with flanking regions.
