OGDA

OGDA catalogs algal organelle genomes, focusing on chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA), to support analyses of genome structure, function, and evolution.

Key Features:

• Dataset composition: Contains plastid genomes (1,055) and mitochondrial genomes (755) in the initial release.
• Taxonomic coverage: Includes algal entries spanning Plantae, Protozoa, Acritarcha, Chromista, and Fungi.
• Data integration: Aggregates organelle genome sequences from various public sources and original sequences from the Laboratory of Genetics and Breeding of Marine Organisms (MOGBL).
• Structural and collinearity analysis: Supports investigation of structural characteristics and collinearity within organelle genomes.
• Phylogenetic analysis: Enables examination of phylogenetic relationships among algal organellar genomes.
• Gene and genome architecture: Facilitates analysis of gene structure and overall genome architecture in plastid and mitochondrial genomes.
• Organelle function and evolution: Supports studies of organelle function and evolutionary processes in algae.
• Genetic inheritance patterns: Provides data suitable for investigations of organelle genetic inheritance across algal lineages.

Scientific Applications:

• Comparative genomics: Comparative analysis of plastid and mitochondrial genomes across diverse algal taxa.
• Phylogenomics: Reconstruction and testing of phylogenetic hypotheses using organellar genome data.
• Evolutionary history: Investigation of evolutionary processes and lineage diversification in algae.
• Genome architecture studies: Analysis of genome structure, rearrangements, and collinearity among organelle genomes.
• Gene function and annotation: Examination of gene structure and potential functional implications in organelles.
• Inheritance and population studies: Analysis of organelle genetic inheritance patterns across algal species.

Methodology:

Organelle genome sequences were integrated from public sources and original sequences produced by the Laboratory of Genetics and Breeding of Marine Organisms (MOGBL); the initial release comprises 1,055 plastid genomes and 755 mitochondrial genomes.
