genetic diversity in 22 accessions of einkorn wheat including thirteen t. boeoticum, four t. monococcum and five t.urartu, evaluated by 24 microsatellite markers originated from a genome of bread wheat. twenty of these ssrs amplified 86 polymorphic fragments among accessions. allele number per locus ranged from 2 to 9 and 4.1 in average. polymorphism information content was calculated from 0.09...

In this study, we analyzed dominant molecular markers to estimate the genetic divergence of 26 popcorn genotypes and evaluate whether using various dissimilarity coefficients with these dominant markers influences the results of cluster analysis. Fifteen random amplification of polymorphic DNA primers produced 157 amplified fragments, of which 65 were monomorphic and 92 were polymorphic. To cal...

Spinach (Spinacia oleracea L.) is an economically important leafy vegetable crop in many countries. This is the first case study of using SRAP markers to analyze genetic diversity of Iranian spinach accessions. Eight SRAP primer combinations generated 88 scorable bands ranging from 50 to 1000 bp, among which 73 were polymorphic, with an average of 82.9 polymorphic bands per primer combination a...

Establishing accurate genetic similarity and dissimilarity between individuals is an essential and decisive point for clustering and analyzing inter and intra population diversity because different similarity and dissimilarity indices may yield contradictory outcomes. We assessed the variations caused by three commonly used similarity coefficients including Jaccard, Sorensen-Dice and Simple mat...

Random Amplified Polymorphic DNA (RAPD) markers was used to analyze the genetic structure of five Indigenous Egyptian’s chicken populations including Fayoumi, Dokki-4, Golden Montazah, Silver Montazah, and ElSalam, based on the taxa generated by the analysis of ten RAPD markers. The population genetic distances were estimated by using two cluster algorithms (UPGMA & NJ neighbor-joining) accompa...

Main point Sibson gives an O(n 2) algorithm for single-linkage clustering, and proves that this algorithm achieves the theoretically optimal lower time bound for obtaining a single-linkage dendrogram. This improves upon the naive O(n 3) implementation of single linkage clustering. A single linkage dendrogram is a tree, where each level of the tree corresponds to a different threshold dissimilar...

A total of 25 adzukibean derived SSR markers were used for molecular diversity analysis among 45 ricebean genotypes and a greengram cultivar, CO 7. Cross species amplification was observed all the in ricebean. Number alleles, present study, varied from one to three. In ricebean, allele size ranged 110 250 bp, whereas it bp. PIC values 0.198 0.689. Out markers, 13 found be polymorphic genotypes....

The Eruca sativa (Taramira) germplasm, comprising 102 accessions was evaluated for total seed storage proteins via sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The accessions were collected from different ecological areas of Pakistan. Total seed storage proteins were electrophoretically separated on 12.5 to 15.0% polyacrylamide gels. A total of 17 protein bands were det...

Figure 1: Dendrogram with a threshold applied (---) to create clusters. The first cluster has genes A and B while the second one has genes C, D, and E. genes to be measured simultaneously. However, interpretation of the large data sets is complex. Commonly used methods include hierarchical clustering and k-nearest-neighbor [3]. After applying these methods, clusters of co-expressed genes are pr...
