gsrc

gsrc detects genome structure rearrangements such as deletions, duplications, and homeologous non-reciprocal translocations (HNRT) from high-density array genotyping data to characterize subgenome exchanges in allopolyploid species.

Key Features:

• Genotype-array-based detection: Identifies genome structure rearrangements using high-density array genotyping data rather than whole-genome sequencing.
• Rearrangement types: Detects deletions, duplications, and homeologous non-reciprocal translocations (HNRT).
• Allopolyploid focus: Targets exchanges between highly similar subgenomes characteristic of allopolyploid species and high synteny contexts.
• Empirical application: Applied to a publicly available dataset for Brassica napus to demonstrate detection of subgenome exchanges.

Scientific Applications:

• Structural variation mapping in allopolyploids: Enables identification of genome structure rearrangements across subgenomes in allopolyploid organisms.
• Phenotypic variation and trait genetics: Supports studies linking deletions, duplications, and HNRT to phenotypic variation and trait architecture.
• Evolutionary and genomic dynamics: Facilitates investigation of subgenome exchanges, genome architecture, and evolutionary dynamics in polyploid species.

Methodology:

Analyzes high-density array genotyping data to detect deletions, duplications and homeologous non-reciprocal translocations (HNRT) and to infer exchanges between subgenomes in allopolyploid species.
