Pergola

Pergola constructs linkage maps for polyploid species to enable accurate marker ordering and estimation of genetic distances for genetic mapping and plant breeding.

Key Features:

• Deterministic and Heuristic Algorithms: Employs both deterministic and heuristic methods for linkage mapping in polyploid genomes.
• Accurate Linkage Metrics: Produces correct linkage groups, marker orders, and genetic distances for simulated and real datasets.
• Performance Superiority: Outperforms existing tools in computational efficiency and mapping accuracy across ploidy levels.
• Dendrogram Representation: Represents linkage maps as dendrograms to facilitate comparison between different maps.

Scientific Applications:

• Plant Breeding: Supports identification of associations between genes and traits in polyploid crops.
• Genetic Mapping: Enables construction of linkage maps for analyses of complex polyploid genomes.
• Crop Improvement: Provides accurate mapping outputs that can inform crop improvement programs for polyploid species.

Methodology:

Implements deterministic and heuristic algorithms for linkage mapping and was validated using simulation studies.
