Recent comparative genomic studies also revealed niche-specific evolution of several LAB, including vaginal lactobacilli and strains used as dairy starter cultures [ 10– 10].
In this study, the comparison of the DNAseq data from 2001 and 2009 gave us an insight into the genome evolution of a lab-adapted strain.
Our phylogenomic analyses provide important insights into the evolution and diversification of LAB species, and also revealed the phylogenetic utility of several genes.
Think of it this way — all life on this planet contains in its genomes the record of 3.5 billion years of evolution, the lab notebooks of evolution's experiments, information about exposure to different infectious diseases, and so much more.
In addition to its contribution to museum collections, Tiktaalik will also be used in our Evolution of the Vertebrates lab course offered through the Department of Integrative Biology.
This result suggests that plasmid-mediated HGT followed by recombination may have contributed to the evolution of lactocepins in LAB.
Now, Lenton and his colleagues suggest that the evolution of land plants may have triggered the glaciations and they've got lab data to back up the idea.
A genome-scale comparative study of these proteins (secretomes) can provide vast information towards the understanding of the molecular evolution, diversity, function and adaptation of LAB to their specific environmental niches.
The exhibition, which has a Web site at digitalcraft.org, traces the 30-year evolution of viruses from computer-lab pastime to global scourge.
