Clonal population structure of Pseudomonas stutzeri, a species with exceptional genetic diversity.
Genetic diversity and genetic relationships among 42 Pseudomonas stutzeri strains belonging to several genomovars and isolated from different sources were investigated in an examination of 20 metabolic enzymes by multilocus enzyme electrophoresis analysis. Forty-two distinct allele profiles were identified, indicating that all multilocus genotypes were represented by a single strain. All 20 loc...
متن کاملComparative genetic diversity of Pseudomonas stutzeri genomovars, clonal structure, and phylogeny of the species.
A combined phylogenetic and multilocus DNA sequence analysis of 26 Pseudomonas stutzeri strains distributed within the 9 genomovars of the species has been performed. Type strains of the two most closely related species (P. balearica, former genomovar 6, and P. mendocina), together with P. aeruginosa, as the type species of the genus, have been included in the study. The extremely high genetic ...
متن کاملWithin-population genetic structure and clonal diversity of a threatened endemic metallophyte, Viola calaminaria (Violaceae).
We studied the within-population genetic structure and the clonality extent of Viola calaminaria, a rare endemic species of calamine soils, by means of RAPD markers in two populations (one recent and one ancient) with expected harsh and heterogeneous heavy-metal stress. At a very local scale (0.2-3 m), clonal propagation was detected in both populations, but the levels of clonal diversity were ...
متن کاملA Comparative Analysis of Genetic Diversity and Structure of Whooper Swan (Cygnus cygnus): A New Considerable Established Population in Iran
New wintering populations of Whooper Swan have been recently reported from west Asia, a lack of information about the population and its origin. The understanding the genetic structure and connectivity are crucial for determining strategies of management for its conservation programs. The samples were collected from two populations in northern Iran, Finland, Sweden, and Iceland, where with larg...
متن کاملSpatial genetic structure and clonal diversity in an alpine population of Salix herbacea (Salicaceae).
BACKGROUND AND AIMS Many alpine plant species combine clonal and sexual reproduction to minimize the risks of flowering and seed production in high mountain regions. The spatial genetic structure and diversity of these alpine species is strongly affected by different clonal strategies (phalanx or guerrilla) and the proportion of generative and vegetative reproduction. METHODS The clonal struc...
