18 de Febrero: Understanding the evolutionary relationships and major traits of Bacillus through comparative genomics.

13 febrero, 2013

Alcaraz, L.D., et al. (2010). Understanding the evolutionary relationships and major traits of Bacillus through comparative genomics. BMC genomics, 11(1), 332. doi:10.1186/1471-2164-11-332 BACKGROUND:The presence of Bacillus in very diverse environments reflects the versatile metabolic capabilities of a widely distributed genus. Traditional phylogenetic analysis based on limited gene sampling is not adequate for resolving the genus…

13 de febrero: Deletional bias and the evolution of bacterial genomes

7 febrero, 2013

Mira, A., Ochman, H., & Moran, N. A. (2001). Deletional bias and the evolution of bacterial genomes, 17(10), 589–596. Retrieved from http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Citation&list_uids=11585665 Although bacteria increase their DNA content through horizontal transfer and gene duplication, their genomes remain small and, in particular, lack nonfunctional sequences. This pattern is most readily explained by a pervasive bias towards…

13 de Febrero: Comparative genomics of gene-family size in closely related bacteria.

7 febrero, 2013

Pushker, R., Mira, A., & Rodriguez-Valera, F. (2004). Comparative genomics of gene-family size in closely related bacteria. Genome Biol, 5(4), 0. Retrieved from http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Citation&list_uids=15059260 BACKGROUND: The wealth of genomic data in bacteria is helping microbiologists understand the factors involved in gene innovation. Among these, the expansion and reduction of gene families appears to have a…
