Random amplified polymorphic DNA (RAPD) diagnostic bands are one tool used to differentiate cryptic mosquito species in the Anopheles albitarsis Complex. Monophyly of four species (A. albitarsis Lynch-Arribálzaga, A. albitarsis B, A. deaneorum Rosa-Freitas, and A. marajoara Galvão & Damasceno) currently identified with the RAPD technique was assessed using sequences of the cytochrome oxidase I ...

Three wild populations of Clarias gariepinus from Esaodo (River Osun), Owena (River Owena), and Agbabu (River Oluwa), and three farmed populations, viz: Akure, Ilesa and Ado-Ekiti, in Southwest Nigeria, were analysed for their genetic differences using Random amplified polymorphic DNA (RAPD) analysis. Live specimens comprising 40 individuals (680 ± 3.28 g) from each location were collected and ...

AIMS The effect of local anaesthetics on optic nerve function can be investigated by quantifying the relative afferent pupillary defect (RAPD). METHODS The study compared the depth of induced RAPD following posterior sub-Tenon's, retrobulbar, and peribulbar local anaesthetics using crossed polarising filters before cataract surgery (time 1 = 5 minutes), immediately after surgery (time 2 = 42 ...

Three different types of molecular markers, RAPD, SSR and fluorescence-based AFLP, were evaluated and compared for their ability to identify oilseed rape cultivars. The direct comparison of RAPD, SSR and AFLP approaches in cultivar identification showed that the AFLP methodology detected polymorphisms more efficiently than either RAPD or SSR methods. For the characterisation of six oilseed rape...

Species-specific Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) markers were used to identify four species related to Anopheles (Nyssorhynchus) albitarsis Lynch-Arribàlzaga from 12 sites in Brazil and 4 in Venezuela. In a previous study (Wilkerson et al. 1995), which included sites in Paraguay and Argentina, these four species were designated "A", "B", "C" and "D". It was...

The objective of this review is to summarize numerous studies on the use of the random amplified polymorphic DNA (RAPD) technique on rice, corn, wheat, sorghum, barley, rye, and oats to examine its feasibility and validity for assessment of genetic variation, population genetics, mapping, linkage and marker assisted selection, phylogenetic analysis, and the detection of somaclonal variation. Al...

A detailed genetic map has been constructed from the F2 population of a single intraspecific cross of Lactuca sativa (n = 9). It comprises 319 loci, including 152 restriction fragment length polymorphism (RFLP), 130 random amplified polymorphic DNA (RAPD), 7 isozyme, 19 disease resistance, and 11 morphological markers. Thirteen major, four minor linkage groups and several unlinked markers are i...

Three shrimps population (Penaeus semesulacatus, Penaeus japonicus,Meta Penaeus monoceros) were investigated for determination of the genetic structure by using (PCR-RAPD) and SDS-PAGE. The results obtained from RAPD technique showed the same percentages of similarity (100%) within the three studied population. On the other hand, the degrees of similarity detected by SDSPAGE were 90%, 87% and 8...

Random amplified polymorphic DNA (RAPD) analysis was used to evaluate genetic diversity among 13 soil Penicillium strains originating from widely dispersed areas. Twenty one of the 34 synthetic random primers were found to identify polymorphism in amplification products. The results show a high level of diversity of RAPD markers among the strains. All the strains could be identified by their ch...
