AFLP is a novel high resolution fingerprinting method that can be used to delineate intraspecific relationships among a large variety of organisms, including bacteria. In the present study, this method was tested for its usefulness in the epidemiological typing of Acinetobacter strains. A total of 25 Acinetobacter strains originating from five hospital outbreaks in three countries were used. Is...

We report on the construction of sex-specific high-density linkage maps and identification of sex-linked markers for the black tiger shrimp (Penaeus monodon). Overall, we identified 44 male and 43 female linkage groups (2n = 88) from the analysis of 2,306 AFLP markers segregating in three full-sib families, covering 2,378 and 2,362 cM, respectively. Twenty-one putatively homologous linkage grou...

seedless barberry (berberis vulgaris l. var. asperma) is one of the few crops that is only cultivated in eastern parts of iran. as a new crop there has not been any study to identify phylogenetic relationships of this plant with other related species existing in iran. in this study, amplification fragment length polymorphism (aflp) markers based on four selected primer combinations (ecori/tru1i...

Amplified fragment length polymorphism (AFLP) was used to analyze the genetic diversity of 14 strains of Xanthomonas arboricola pv. pruni and seven strains of X. axonopodis pv. phaseoli, which are used in xanthan production studies. Relationships identified by the AFLP profiles were assessed for xanthan production capacity, geographical location and host plant. Strains were isolated from 10 dif...

We have examined the global population genetic structure of Haemonchus contortus. The genetic variability was studied using both amplified fragment length polymorphism (AFLP) and nad4 sequences of the mitochondrial genome. To examine the performance and information content of the two different marker systems, comparative assessment of population genetic diversity was undertaken in 19 isolates o...

Expression profiling using cDNA-AFLP is commonly used to display the transcriptome of a specific tissue or developmental stage. Here cDNA-AFLP was used to identify transcripts in a segregating F1 population of Phytophthora infestans, the oomycete pathogen that causes late blight. To find transcripts derived from putative avirulence (Avr) genes germinated cyst cDNA from F1 progeny with defined a...

ABSTRACT To investigate disease resistance gene analogs (RGAs) encoding coiled-coil-nucelotide-binding site-leucine-rich repeats (CC-NBS-LRR) proteins in western white pine, degenerate primers targeting the conserved motifs in the NBS domain were designed to amplify RGAs from genomic DNA and cDNA. Sixty-one distinct RGAs were identified with identities to well-known R proteins of the CC-NBS-LRR...

The Pvr4 resistance gene in pepper confers a complete resistance to the three pathotypes of potato virus Y (PVY) and to pepper mottle virus (PepMoV). In order to use this gene in a marker-assisted selection (MAS) program and to permit the pyramiding of several potyvirus resistance genes in the same cultivar, tightly linked amplified fragment length polymorphism (AFLP) markers were obtained by t...

Amplified fragment length polymorphism (AFLP) is often used for genetic mapping and diversity analysis, but very little information is currently available on their sequence characteristics. Species-specific sequences were analyzed from a single Coffea genome (Coffea pseudozanguebariae) associated with clustered or nonclustered AFLP loci of known genetic position. Compared with the expressed seq...
