Genes involved in yellow pigmentation of Cronobacter sakazakii ES5 and influence of pigmentation on persistence and growth under environmental stress.
Cronobacter spp. are opportunistic food-borne pathogens that are responsible for rare but highly fatal cases of meningitis and necrotizing enterocolitis in neonates. While the operon responsible for yellow pigmentation in Cronobacter sakazakii strain ES5 was described recently, the involvement of additional genes in pigment expression and the influence of pigmentation on the fitness of Cronobac...
متن کاملGenes under positive selection in Escherichia coli.
We used a comparative genomics approach to identify genes that are under positive selection in six strains of Escherichia coli and Shigella flexneri, including five strains that are human pathogens. We find that positive selection targets a wide range of different functions in the E. coli genome, including cell surface proteins such as beta barrel porins, presumably because of the involvement o...
متن کاملPigmentation in Human Skin
Topica! tyrosine has been proposed as a tanning accelerator because tyrosine is a precursor of melanin. We tested formulations containing O, 1, and 2% L-tyrosine topically on 14 individuals daily for 28 days. Percutaneous absorption using "C tyrosine was 1.23% in 24 hr. No enhanced pigmentation was clinically evident in any of the subjects. In this study, we were unable to demonstrate that topi...
متن کاملNatural selection along an environmental gradient: a classic cline in mouse pigmentation.
We revisited a classic study of morphological variation in the oldfield mouse (Peromyscus polionotus) to estimate the strength of selection acting on pigmentation patterns and to identify the underlying genes. We measured 215 specimens collected by Francis Sumner in the 1920s from eight populations across a 155-km, environmentally variable transect from the white sands of Florida's Gulf coast t...
متن کاملRepeated divergent selection on pigmentation genes in a rapid finch radiation
Instances of recent and rapid speciation are suitable for associating phenotypes with their causal genotypes, especially if gene flow homogenizes areas of the genome that are not under divergent selection. We study a rapid radiation of nine sympatric bird species known as capuchino seedeaters, which are differentiated in sexually selected characters of male plumage and song. We sequenced the ge...
