چکیده

We tested the constancy of l inkage relat ionships of randomly amplif ied polymorphic DNA (RAPD) marker loci used to construct a population-based consensus map in material from an Italian stand of Picea abies (L.) Karst. in 29 individuals from three Norwegian populations. Thirteen marker loci linked in the Italian stand did show a consistent locus ordering in the Norwegian population. The remaining 16 unlinked marker loci were spread over different linkage groups and (or) too far apart both in the population map and in this study. The limited validity of RAPD markers as genomic “hallmarks” resilient across populations is discussed. We also investigated the reliability of RAPD markers; only 58% of the RAPD markers previously used to construct the consensus map in the Italian population were repeatable in the same material . Of the repeatable ones 76.3% were amplified and found polymorphic in 29 megagametophyte sibships from three Norwegian popula t ions . R&urn6 : Les auteurs ont voulu verifier, chez 29 individus provenant de trois populations norvegiennes de Pica abies (L.) Karst., la stabilite des relations de liaison entre les loci de marqueurs d’amplification au hasard des polymorphismes de I’ADN (RAPD) utiiises pour construire une carte consensus de population a partir de materiel qui origine d’un peuplement italien de Ia m&me espece. Un groupe de 13 loci de marqueurs du peuplement italien a demontre un ordre similaire des loci chez les populations norvegiennes. Les autres I6 loci de marqueurs non lies Ctaient repartis entre differents groupes de liaison et (ou) Ctaient trop CIoignCs Ies uns des autres, a Ia fois sur Ia carte de la population itaIienne et dans la presente etude. Les auteurs discutent de Ia validite IimitCe des marqueurs RAPD comme marqueurs genomiques universels stables d’une population a l’autre. Les auteurs ont Cgalement CtudiC la fiabilite des marqueurs RAPD. Seulement 58% des marqueurs RAPD utilises precedemment pour construire Ia carte consensus de Ia population italienne Ctaient reproductibles chez Ie meme materiel. Parmi les marqueurs reproductibles, 76,3% ont pu &tre amplifies et ont demontre du polymorphisme chez les 29 families de megagametophytes des trois populations norvegiennes.

Use of randomly amplified polymorphic DNA markers for the genetic analysis of relatedness and diversity in chickens and turkeys.

A study involving the use of random amplified polymorphic DNA (RAPD) was conducted to evaluate genetic polymorphism and relatedness within and among four chicken breeds: Araucona, Rhode Island Red, White Leghorn, and White Plymouth Rock, and two turkey populations, a long-term randombred and a commercial strain. A total of 60 random primers were used in the RAPD analyses. Forty-two of the 60 pr...

A composite genetic map of the parasitoid wasp Trichogramma brassicae based on RAPD markers.

Three linkage maps of the genome of the microhymenopteran Trichogramma brassicae were constructed from the analysis of segregation of random amplified polymorphic DNA markers in three F2 populations. These populations were composed of the haploid male progeny of several virgin F1 females, which resulted from the breeding of four parental lines that were nearly fixed for different random amplifi...

Identification and characterization of RAPD markers inferring genetic relationships among Pine species.

Total genomic DNAs were extracted from several populations of pine species and amplified using oligonucleotides of random sequences. Polymorphism in random amplified polymorphic DNA (RAPD) markers was high and sufficient in distinguishing each of the species. Genetic relationships among eight pine species (Pinus sylvestris, Pinus strobus, Pinus rigida, Pinus resinosa, Pinus nigra, Pinus contort...
