TYGS is an automated high-throughput platform for state-of-the-art genome-based taxonomy

Abstract: Microbial taxonomy is increasingly influenced by genome-based computational methods. Yet such analyses can be complex and require expert knowledge. Here we introduce TYGS, the Type (Strain) Genome Server, a user-friendly high-throughput web server for genome-based prokaryote taxonomy, connected to a large, continuously growing database of genomic, taxonomic and nomenclatural information. It infers genome-scale phylogenies and state-of-the-art estimates for species and subspecies boundaries from user-defined and automatically determined closest type genome sequences. TYGS also provides comprehensive access to nomenclature, synonymy and associated taxonomic literature. Clinically important examples demonstrate how TYGS can yield new insights into microbial classification, such as evidence for a species-level separation of previously proposed subspecies of Salmonella enterica. TYGS is an integrated approach for the classification of microbes that unlocks novel scientific approaches to microbiologists worldwide and is particularly helpful for the rapidly expanding field of genome-based taxonomic descriptions of new genera, species or subspecies.

Arabidopsis Genome Initiative

Abstract: Arabidopsis (rockcress) is a genus in the family Brassicaceae. Representatives of Brassicaceae family are small-flowering plants, some of them are important crops such as cabbage, cauliflower, radish, and canola. Arabidopsis genus includes nine species and eight subspecies. The subspecies delimitation is quite recent, and is based on morphological and molecular phylogenetics (Elizabeth 2000). Arabidopsis thalianacommonly known as thale cress, has 10 chromosomes in diploid stage and was the first plant to have its entire genome sequenced. Most of the species in Arabidopsis are indigenous to Europe and only two species are found in North America and Asia.

Abstract: Describes the physical features, field identification, habitat, distribution, migration, reproduction, and habits of American species and subspecies north of Mexico.
