This study investigated the genetic diversity of morchella species using randomly amplified polymorphic DNA markers. Morchella species are an important group of edible mushrooms belonging to the family Helveliaceae with medicinal and economical significance. In this study we have developed an efficient method of genomic DNA isolation which was amplified by eight RAPD primers to test the polymor...

To clarify the virulence and phylogenetic implications of antimicrobial agent resistance in Escherichia coli, 100 E. coli isolates from urine samples of Israeli women with acute uncomplicated cystitis were analyzed by molecular phylotyping and virulence genotyping for comparison with resistance phenotypes. The differences between the isolates that were resistant and susceptible to trimethoprim-...

Although the evolutionary functions of attachment in infant-caregiver relationships are undisputed, it is unclear what functions--if any--attachment serves in adult romantic relationships. The objective of this research was to examine the evolution and function of adult attachment (i.e., pair bonding) by applying comparative and phylogenetic methods to archival data collected on 2 diverse sampl...

BACKGROUND There exists substantial variation in human stature and sexual stature dimorphism that has been attributed to both genetic and environmental variables. A few studies have previously investigated possible relationships between latitude and stature, building on the idea that variation in climate can influence body size (Bergmann's rule). This change in body size can in turn have influe...

The control region is considered to be one of the most variable parts of animal mitochondrial DNA (mtDNA). We compared the mtDNA control region from 37 species representing 14 genera and 4 subfamilies of Ranidae, to analyze the evolution of the control region and to determine their phylogenetic relationship. All the Ranidae species had a single control region, except four species that had two r...
