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...

Genetic diversity among 20 sesame (Sesamum indicum L.) accessions was examined at DNA level by means of random amplified polymorphic DNA (RAPD) analysis. Ten primers used produced a total of 93 RAPD fragments, of which 70 (75%) were polymorphic. Each primer generated 5 to 17 amplified fragments with an average of 9.3 bands per primer. Based on pair-wise comparisons of RAPD amplification product...

The objective of this work is to present an appropriate set of RAPD (random amplified polymorphic DNA) markers using single and multiplex PCR analysis suitable for the characterization of the endemic Cuban species Carica cubensis and the establishment of genetic relationships with the cultivated species Carica papaya. RAPD markers presented a high level of polymorphism. In addition, the incorpo...

Dimocarpus longan Lour. is an edible and traditional herb in China, commonly referred to as longon. An improved randomly amplified polymorphic DNA (RAPD) protocol was here developed in order to determine the geographical origins of D. longan samples collected from 5 provinces in the southern and southwestern areas of China, including Sichuan, Hainan, Fujian, Guangdong, and Guangxi. Generally, t...

The RAPD-PCR technique was applied to identify genetic markers able to distinguish between four canid species: the arctic fox (Alopex lagopus), red fox (Vulpes vulpes), Chinese raccoon dog (Nyctereutes procyonoides procyonoides) and six breeds of the domestic dog (Canis familiaris). A total of 29 ten-nucleotide arbitrary primers were screened for their potential use in the differentiation of th...

Edwardsiella tarda is an enterobacterial fish pathogen that causes mortality in various fish species worldwide. In this study, we analyzed the intraspecific variability in a collection of E. tarda strains isolated from turbot. To do this we employed 4 polymerase chain reaction (PCR)-based methods: (1) random amplified polymorphic DNA (RAPD), (2) enterobacterial repetitive intergenic consensus-P...

In the current study we aimed to execute a rather less complicated molecular tying method, i.e. the random amplification of polymorphic DNA (RAPD) analysis to find the heterogeneity of Iranian strains of Mycobacterium tuberculosis. The isolates comprised a total of 96 strains of M. tuberculosis collected from clinical specimens of patients in Isfahan and Tehran. The isolates were assigned to th...

Molecular characterization of eleven clones of C. winterianus collected from eleven districts of West Bengal was carried out with 10 RAPD and 9 ISSR primers. The RAPD primers developed 81 robust loci, which revealed 74.07% polymorphism and 61 ISSR markers generated 47.50% polymorphism. Out of the different anchored primer combinations, ISSR primers with AG and GA motifs produced clear and maxim...

We used 199 Corynebacterium diphtheriae isolated from 1995 to 1997 in Russia to evaluate the ability of random amplified polymorphic DNA (RAPD) to identify the unique clonal group that emerged there in 1990. Our data show that RAPD can reliably, reproducibly, and rapidly screen a large number of strains to identify the epidemic clonal group.

The screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), is one of the most devastating arthropod pests of livestock in the Western Hemisphere. Early instars are very difficult to distinguish morphologically from several closely related blow fly species. Random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) markers were developed for identifying C. hominivorax...
