Origanum syriacum L. (Lamiaceae) is a perennial species with an important role in medicinal and pharmaceutical applications. However, the attention regarding its genetic diversity negligible worldwide. Touch-up direct amplification of minisatellite-region DNA (TU-DAMD) marker has been employed to investigate natural populations, where 37 wild O. genotypes were collected from coastal, central so...

Microsatellites, tandem repeats of short nucleotide (1-6 bp) sequences, are the DNA marker of choice because of their highly polymorphic, ubiquitous distribution within genome, ease of genotyping through polymerase chain reaction (PCR), selectively neutral, co-dominant and multi allelic nature. Six microsatellites, three polymorphic and three monomorphic, have been characterized for the first t...

We illustrate the use of functional system speci cations and their re nement in the development of system components by a simple case study The development includes the modular speci cation re nement and veri cation of system components We start the development with an informal description of the tasks of the case study and then step by step carry out the tasks formally The informal requirement...

PREMISE OF THE STUDY Polymorphic microsatellite loci were characterized in the dioecious neotropical rainforest tree Virola sebifera. The markers will be used to study ecological and genetic impacts of hunting and landscape change in this vertebrate-dispersed, insect-pollinated tree species. METHODS AND RESULTS Simple sequence repeat (SSR) markers were screened from genomic libraries of South...

Seed oil and seed protein contents are commercially important components of soybean (Glycine max (L.) Merr.) that inversely correlated. The objectives this study were to identify novel quantitative trait loci (QTL) validate existing QTL associated with oil, protein, weight in soybean. Two mapping populations, Pop 201 202, consisting 180 170 recombinant inbred lines (RILs), respectively, used st...

The nature of the forces affecting base composition is a key question in genome evolution. There is uncertainty as to whether differences in the GC contents of non-coding sequences reflect differences in mutational bias, or in the intensity of selection or biased gene conversion. We have used a polymorphism dataset for non-coding sequences on the X chromosome of Drosophila simulans to examine t...

Network worms are malicious programs that spread automatically across networks by exploiting vulnerabilities that affect a large number of hosts. Because of the speed at which worms spread to large computer populations, countermeasures based on human reaction time are not feasible. Therefore, recent research has focused on devising new techniques to detect and contain network worms without the ...
