Einkorn (Triticum monococcum L. ssp. monococcum) is an ancient diploid wheat species with many useful traits and used as a gene discovery model. In this research, total of 41 tetraploid accessions were tested using simple sequence repeat (SSR) markers. A 33 genotypes T. along four each (T. dicoccon durum) plant material. The analysis utilized 10 polymorphic markers, including number alleles ave...

The problem is to construct an optimal weight tree from the 3 ( n 4 ) weighted quartet topologies on n objects, where optimality means that the summed weight of the embedded quartet topologies is optimal (so it can be the case that the optimal tree embeds all quartets as nonoptimal topologies). We present a Monte Carlo heuristic, based on randomized hill climbing, for approximating the optimal ...

Twelve Aspergillus sp. strains producing glucose dehydrogenase were identified using ITS region sequencing. Based on the sequences obtained, the genomic relationship of the analyzed strains was investigated. Moreover, partial gdh gene sequences were determined and aligned. The amplified fragment length polymorphism (AFLP) method was applied for genomic fingerprinting of twelve Aspergillus isola...

Brazil has one of the greatest diversities in native fruit trees, but many species, despite great environmental and economic potential for small farms, are little studied, such as cherry-of-the-rio-grande (Eugenia involucrata DC.). The hypothesis this research was that there is a high genetic diversity due to propagation by seeds, occurring genotypes produce better quality fruits which can be u...

Information on the genetic identity and interrelationships of different Morus spp. genotypes is essential for their proper conservation and utilization. Hence, the present investigation was undertaken with genetically more reliable DNA markers to study the genetic relationship among eleven selected genotypes of mulberry collected from Japan, India and Italy. Using ten RAPD and ten ISSR primers,...

Paris polyphylla Sm. is a vulnerable medicinal plant distributed in the Himalayan countries. This has numerous pharmacological benefits, including anticancer, anti-inflammatory, analgesic, and antipyretic properties. The distribution, conservation status, traditional usage of this species are fairly known Nepal. However, its diversity population structure at molecular level unexplored. study an...

?The success of 16 methods of phylogenetic inference was examined using consis? tency and simulation analysis. Success?the frequency with which a tree-making method cor? rectly identified the true phylogeny?was examined for an unrooted four-taxon tree. In this study, tree-making methods were examined under a large number of branch-length conditions and under three models of sequence evolution. ...

MOTIVATION With the advent of microarray chip technology, large data sets are emerging containing the simultaneous expression levels of thousands of genes at various time points during a biological process. Biologists are attempting to group genes based on the temporal pattern of their expression levels. While the use of hierarchical clustering (UPGMA) with correlation 'distance' has been the m...
