Genomic heterogeneity in Chlorobium limicola: chromosomic and plasmidic differences among strains.

abstract：:The Saccharomyces sensu stricto genus contains many species that are industrially important for fermentation of wines, beers and ales. The molecular characterization of the genomes of yeasts involved in these processes reveals that the majority arose from interspecific hybridization between two and sometimes three yea...
