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...
Amplified fragment length polymorphism (AFLP) analysis is currently the most powerful and efficient technique for the generation of large numbers of anonymous DNA markers in plant and animal genomes. We have developed a protocol for high-throughput AFLP analysis that allows up to 70,000 polymorphic marker genotype determinations per week on a single automated DNA sequencer. This throughput is b...
The objective of this study was to evaluate the usefulness of amplified fragment length polymorphism (AFLP) analyses for selection of the best parents for breeding of hybrid winter triticale. Phenotypic diversity was measured for 8 agronomic traits in 10 parents and 27 F1 hybrids. Genotypic diversity was measured by 91 AFLP markers. Coefficients of correlation of genetic similarity (AFLP-GS) wi...
Soybean [Glycine max (L.) Merrill] is the most important leguminous crop in the world due to its high contents of high-quality protein and oil for human and animal consumption as well as for industrial uses. An accurate and saturated genetic linkage map of soybean is an essential tool for studies on modern soybean genomics. In order to update the linkage map of a F2 population derived from a cr...
The present work was conducted to evaluate AFLP (Amplified Fragment Length Polymorphism) and SSR (Simple Sequence Repeat) marker systems for their ability to detect genetic diversity within a set of 29 common bean accessions spanning both the Andean and Mesoamerican gene pools and to compare the efficiency of these two marker types in the classification of accessions according to the gene pools...
Amplification fragment-length polymorphism (AFLP) analysis has proven to be a powerful tool for developing a large number of reliable genetic markers across a wide variety of organisms. Often it is desirable to further characterize these markers by obtaining internal and flanking sequence information. Here, we present a systematic approach for obtaining such information from AFLP markers. AFLP ...
A strategy based upon AFLP markers for high-efficiency mapping of morphological mutations and DNA probes to linkage groups in barley is presented. First, 511 AFLP markers were placed on the linkage map derived from the cross Proctor x Nudinka. Second, loci controlling phenotypic traits were assigned to linkage groups by AFLP analysis, using F2 populations consisting of 30-50 mutant plants deriv...
The amplified fragment length polymorphism (AFLP) technique was applied to identify palm varieties. Fluorescence labelled primers were used in selective amplifications and the amplified fragments were detected on capillary gel electrophoresis using an automated DNA sequencer with the analysis fragment option. This is a rapid and efficient technique for detecting a large number of DNA markers on...
Mimicry and extensive geographical subspecies polymorphism combine to make species in the ithomiine butterfly genus Mechanitis (Lepidoptera; Nymphalidae) difficult to determine. We use mitochondrial DNA (mtDNA) barcoding, nuclear sequences and amplified fragment length polymorphism (AFLP) genotyping to investigate species limits in this genus. Although earlier biosystematic studies based on mor...
