DANTE_LTR

DANTE_LTR identifies and annotates complete long terminal repeat (LTR) retrotransposons in plant genomes to enable domain-based detection and phylogenetic classification of these elements.

Key Features:

• Domain-based Annotation: Uses DANTE to detect conserved protein domains within genome sequences for LTR retrotransposon identification.
• Structural Feature Detection: Parses DANTE domain outputs and recognizes structural features such as terminal repeats to annotate complete element sequences in adjacent regions.
• Phylogenetic Classification: Classifies LTR retrotransposons into phylogenetic lineages using domain sequence information, enabling resolution beyond superfamily-level assignment.
• Benchmarking and Accuracy: Tested across 93 plant genomes and reports detection of a higher number of intact LTR retrotransposons compared with several established pipelines.

Scientific Applications:

• Plant genome annotation: Annotation of complete LTR retrotransposon sequences within assembled plant genomes.
• Evolutionary biology: Reconstruction of phylogenetic relationships among LTR retrotransposon lineages using domain sequences.
• Functional genomics: Analysis of LTR retrotransposon impact on genome structure and gene regulation.
• Comparative genomics: Cross-species comparison of LTR retrotransposon composition and lineage distribution.

Methodology:

Detect conserved protein domains with DANTE, input domain hits into the DANTE_LTR pipeline to recognize structural features (including terminal repeats) and annotate complete elements, and classify elements into phylogenetic lineages based on domain sequences; benchmarking performed across 93 plant genomes versus other pipelines.
