Introduction: The natural ecosystems of northern Mato Grosso, Brazil, are in process fragmentation, mainly due to population growth and the expansion agriculture. This endangers palm Euterpe precatoria (locally known as açaí), used for construction, hearts, juices ice cream. Objective: To evaluate local diversity genetic structure native populations E. precatoria. Methods: We collected leaves f...

Four cattle breeds (Gyr, Nellore, Guzerat and Holstein) were analyzed by amplification of genomic DNA using microsatellite loci to evaluate the genetic diversity within and among them. DNA samples of 18 animals from each breed were collected to access the genetic content of them. Allele frequencies were calculated and used to generate a Nei’s genetic distance matrix what was used to build a den...

We present a set of analyses aiming at quantifying the amount of information filtered by di↵erent hierarchical clustering methods on correlations between stock returns. In particular we apply, for the first time to financial data, a novel hierarchical clustering approach, the Directed Bubble Hierarchical Tree (DBHT), and we compare it with other methods including the Linkage and k-medoids. In p...

Ochradenus Delile is a small genus of 6-9 species within family Resedaceae. In Egypt, it is only represented by the gynodioecious Ochradenus baccatus Delile, the most widespread species across the entire range of the genus. Within Egypt, field populations and herbarium specimens of O.baccatus showed vast morphological and gender diversity within and between different populations even in the sam...

In the present study, genetic diversity among 16 collections of Stevia rebaudiana Bertoni was assessed to compare the efficiency of two-marker systems over one marker using RAPD and ISSR markers. How well these two marker systems discriminated the Stevia collections was compared. In fact, all the Stevia accessions included in the present study have been growing under different altitudes, rangin...

Ipomoea genus is widely distributed in the tropical and subtropical regions of the world. The exploration of genetic diversity is pre-requisite for genome organization in the wild species and the related domesticated ones. Inter-simple Sequence Repeat (ISSR) markers was used to assess the identification of 21 important Ipomoea species and determination of the genetic relationships among these s...

Barilius bendelisis is an important food fish and a demanding ornamental species in India. Despite its great economic importance, several wild populations have been suffering drastic reduction. The genetic variability within population is extremely useful for gathering information on individual’s identity, breeding patterns, degree of relatedness and disturbance of genetic variation among them....

A number of different markers (proteins, isoenzymes and RAPDs) have been used to settle taxonomic disputes and to assess genotype variability in populations of the genus Prosopis, in order to select highly productive phenotypes. In this study the genetic variability of two wild populations of Prosopis laevigata located in the Mexican states of Guanajuato (population 1) and Hidalgo (population 2...

The objective of this study was to evaluate whether different similarity coefficients used with dominant markers can influence the results of cluster analysis, using eighteen inbred lines of maize from two different populations, BR-105 and BR-106. These were analyzed by AFLP and RAPD markers and eight similarity coefficients were calculated: Jaccard, Sorensen-Dice, Anderberg, Ochiai, Simple-mat...

Genetic polymorphism was studied among thirty Indian mustard genotypes using 20 ISSR primers. This study revealed 156 amplified bands with an average of 7.8 bands per primer out of which 115 were polymorphic. Size of amplified fragments ranged from 100 bp to 1500 bp and number varied from 4 to 14. ISSR data were used to compute genetic similarities based on Jaccrad’s similarity coefficient, it ...
