The more than 100 almond cultivars grown in Apulia (South Italy) could be a source of genetic variation adapted to the Mediterranean environment, provided that a proper classification, identifying similar characteristics and synonymous cultivars, is made. DNA-based assays could integrate traditional classifications based on morphology. In the comparison of 17 Apulian almond cultivars, by random...

The QuikChange Multi Site-Directed Mutagenesis Kit is a simple and efficient method for introducing point mutations at up to five sites simultaneously in plasmid DNA templates. Here we used the QuikChange Multi kit with degenerate (one codon) primers to introduce all possible amino acids at selected sites in the lacZ gene. In reactions employing two or three degenerate primers, diverse librarie...

Long-read RNA sequencing allows for the precise characterization of full-length transcripts, which makes it an indispensable tool in transcriptomics. The human cytomegalovirus (HCMV) genome has been first sequenced in 1989 and although short-read sequencing studies have uncovered much of the complexity of its transcriptome, only few of its transcripts have been fully annotated. We hereby presen...

Eighty-seven isolates of Colletotrichum graminicola, mostly from Agrostis palustris, were collected in grass fields, most of which were in Ontario, Canada. Specific primers were designed to amplify the mating-type (MAT) genes and, among 35 isolates tested, all yielded a band of the expected size for MAT2. For six isolates, the MAT2 PCR products were sequenced and found to be similar to that rep...

Gypsophila L. is the 3rd-largest genus of Caryophyllaceae in Turkey, a country that includes 60 taxa belonging to 56 species of the 126 recognized in the genus. A total of 35 taxa are endemic to Turkey, with an approximately 60% endemism ratio. In this study, the genetic diversity of 14 Gypsophila species from Turkey was analyzed using random amplification of polymorphic DNA (RAPD) and inter-si...

Anopheles (Nyssorhynchus) marajoara is a proven primary vector of malaria parasites in Northeast Brazil, and An. deaneorum is a suspected vector in Western Brazil. Both are members of the morphologically similar Albitarsis Complex, which also includes An. albitarsis and an undescribed species, An. albitarsis "B". These four species were recognized and can be identified using random amplified po...

Genetic variability among the genotypes of any species could be utilized for its improvement. PCR-based Random Amplified Polymorphic DNA (RAPD) technique was used to determine the genetic diversity and relationship among 10 cucumber varieties and genotypes. Five decamer primers were used to amplify genomic DNA and the primers yielded a total of 54 bands of which 36 bands were polymorphic and 18...

In this work, we described a new approach for the isolation of a species-specific probe for the Eimeria media parasite of the rabbit based on the use of the random amplified polymorphic DNA (RAPD) technique. A specific fragment of 800 bp of the studied species was isolated after RAPD and then cloned and DIG-radiolabeled. After dot-blotting, we observed that this probe was specific for E. media....

Random amplified polymorphic DNA markers were used to evaluate the genetic diversity in a representative population of Terminalia pallida from six different geographical regions of chittoor district. 20 OPA primers were used for the RAPD analysis. A total of 33 bands yielded from 7 reproducible primers, with a mean of 4.28 amplified bands per primer. The plant species showed 69.5% polymorphism....

The Anopheles dirus Peyton & Harrison complex of mosquitoes (Diptera: Culicidae) comprises seven known species, including important malaria vectors in Southeast Asia. Specific identification of each species of the complex, which cannot be distinguished using morphological characters, is crucial for understanding vector ecology and implementing effective control measures. Derived from individual...
