PseudoBase

PseudoBase provides integrated genomic sequences, standardized variant calls, and embedded genomic visualization to support comparative and evolutionary genomic analyses of the Drosophila pseudoobscura subgroup (D. pseudoobscura, D. persimilis, D. miranda, and D. lowei).

Key Features:

• Extensive Genomic Data Integration: Consolidates publicly available genome sequences for the Drosophila pseudoobscura subgroup (D. pseudoobscura, D. persimilis, D. miranda, and D. lowei).
• Genomic Visualization and Query Capabilities: Provides visualization of genomic regions and supports queries of alignments and genomic coordinates.
• Consistent Genetic Variation Analysis: Reports single nucleotide polymorphisms (SNPs) and insertions/deletions (indels) derived from a standardized workflow for cross-dataset comparison.
• Embedded JBrowse Interface: Incorporates JBrowse to visualize genomic alignments directly within the platform.
• Batch Access for Gene Lists: Supports batch queries on gene lists to retrieve data for multiple genes or regions simultaneously.

Scientific Applications:

• Intraspecific Variation Analysis: Enables analysis of genetic variation within species of the D. pseudoobscura subgroup.
• Comparative Genomics: Facilitates genome comparisons across D. pseudoobscura, D. persimilis, D. miranda, and D. lowei.
• Evolutionary Genetics: Supports studies of evolutionary processes and genetic divergence within the subgroup.
• Genotype–Phenotype Investigation: Provides data resources to explore genetic underpinnings of phenotypic traits within the subgroup.

Methodology:

Consolidation of publicly available genome sequences; generation of SNPs and indels via a standardized variant-calling workflow; integration of JBrowse for alignment visualization; batch processing of gene-list queries.
