A glimpse at an early stage of microbe domestication revealed in the variable g...
Silva, Margarida; Pontes, Ana; Franco-Duarte, Ricardo; Soares, Pedro; Sampaio, José Paulo; Sousa, Maria João; Brito, Patrícia HMicrobe domestication has a major applied relevance but is still poorly understood from an evolutionary perspective. The yeast Torulaspora delbrueckii is gaining importance for biotechnology but little is known about its population structure, variation in gene content or possible domestication routes. Here, we show that T. delbrueckii is composed of five major clades. Among the three European clades, a lineage ...
Genetic Competence Drives Genome Diversity in Bacillus subtilis
Brito, Patrícia H; Chevreux, Bastien; Serra, Cláudia R; Schyns, Ghislain; Henriques, Adriano O; Pereira-Leal, José BProkaryote genomes are the result of a dynamic flux of genes, with increases achieved via horizontal gene transfer and reductions occurring through gene loss. The ecological and selective forces that drive this genomic flexibility vary across species. Bacillus subtilis is a naturally competent bacterium that occupies various environments, including plant-associated, soil, and marine niches, and the gut of both ...
Rethinking the Niche of Upper-Atmosphere Bacteria: Draft Genome Sequences of Ba...
Ramos-Silva, Paula; Brito, Patrícia H; Serrano, Mónica; Henriques, Adriano O; Pereira-Leal, José BHere, we report two genome sequences of endospore-forming bacteria isolated from the rice fields of Comporta, Portugal, identified as Bacillus aryabhattai C765 and Bacillus aerophilus C772. Both species were previously identified in air samples from the upper atmosphere, but our findings suggest their presence in a wider range of environmental niches.
