MEGANTE

MEGANTE annotates plant genomes by executing integrated analyses to predict exon–intron structures, identify open reading frames (ORFs), and assign functional annotations from similarity and domain searches.

Key Features:

• Automated analysis pipeline: Executes multiple analysis programs to determine consensus exon–intron structures and predict ORFs at each genomic locus.
• Similarity searches: Performs similarity searches against known proteins to support functional annotation of predicted sequences.
• Functional domain identification: Identifies functional domains within predicted ORFs to aid annotation of protein features.
• Annotation visualization: Visualizes annotation tracks using GBrowse for genomic interpretation.
• Output formats: Exports annotation results in Microsoft Excel format for downstream analysis.
• Species coverage: Supports 24 plant species across families including Brassicaceae, Fabaceae, Musaceae, Poaceae, Salicaceae, Solanaceae, Rosaceae, and Vitaceae.
• Sequence submission limits: Accepts sequences up to 10 Mb in length and allows saving annotations for up to 100 sequences.

Scientific Applications:

• Gene discovery: Supports identification and structural annotation of genes in plant genomes.
• Functional genomics: Facilitates assignment of putative functions to predicted coding sequences through similarity and domain analyses.
• Comparative genomics: Provides annotated gene models and protein-level information useful for cross-species comparisons.

Methodology:

Integrates multiple bioinformatics algorithms to perform sequence alignment, exon–intron structure prediction, ORF identification, and functional domain searches.
