Microsatellite (MS) is a genetic marker widely used in the studies of pedigree, individual identification, gene mapping, and genetic diversity within and between populations. The genetic diversity of the indigenous Ven dog breed, along with two imported dog breeds, the Berger and Poodle dogs raised in Vietnam, was analyzed based on seven microsatellite markers.

The Tajima’s test indicated that the analysed population in balancing selection with a D-value of 2.39. A phylogenetic tree based on 455 bp of hypervariable mtDloop sequence classified 17 Bang Troi chicken individuals into three clades A, B, and E, which are common groups of Vietnamese and Asia indigenous chickens. This result provides the first genetic information and maternal lineages of Bang Troi chickens and it can support for registration of local chicken breeds.

Genetic diversity among 28 sesame (Sesamum indicum L.) varieties was examined at DNA level by means of random amplified polymorphic DNA (RAPD) analysis. Fifteen primers used produced a total of 132 RAPD fragments. Each primer generated 3 to 26 amplified fragments with an average of 8.8 bands per primer. Based on pair-wise comparisons of RAPD amplification products, Nei and Li’s similarity coefficients were computed to assess the associations among the varieties. Pair-wise similarity indices varied from 0.35 to 0.84.

Assessment of genotype diversity was studied using released and in pipeline genotypes of wheat, of these 22 were released and 14 were in pipeline . Genetic diversity among 36 wheat genotypes was studied using Random amplified polymorphic DNA (RAPD) analysis. 21 RAPD primers (RPI primers) were used for screening 36 wheat genotypes from which 2,868 fragments were amplified. It was observed that 63.3% bands were polymorphic and 36.4% were monomorphic. The percent of polymorphic bands in banding pattern was calculated and it was highest in RPI-22 (81.3%) while lowest was recorded in RPI-2 (33.

Cycads occur in lowland forests and are threatened by their degradation, fragmentation and over-exploitation. Our results indicate that cycad population sizes were very small (less 100 individuals) with high propagules. These increased mating between closely related individuals growing in clumps. The allozyme data show although all studied cycads maintained high levels of genetic diversity, an average of 0.556 (0.491 in C. hoabinhensis to 0.598 in C. chevalieri ), the degree of inbreeding was high.

In this study, a total of sixteen RAPD primers were used for evaluation of the genetic diversity of eight H. serrata samples collected from different locations of Sa Pa and Da Lat. Overall, sixteen markers generated a total of 70 fragments in 8 collected samples of H. serrata. Of seventy generated fragments, 44 were found to be polymorphic.

Murine double minute 2 (MDM2) protein exhibits many diverse biochemi-cal functions on the tumour suppressor protein p53, including transcrip-tional suppression and E3 ubiquitin ligase activity. However, more recent data have shown that MDM2 can exhibit ATP-dependent molecular chap-erone activity and directly mediate folding of the p53 tetramer. Analysing the ATP-dependent function of MDM2 will provide novel insights into the evolution and function of the protein.

Functional diversity of potassium channels in both prokaryotic and euk-aryotic cells suggests multiple levels of regulation. Posttranslational regula-tion includes differential subunit assembly of homologous pore-forming subunits. In addition, a variety of modulatory subunits may interact with the pore complex either statically or dynamically. Kv2.1 is a delayed recti-fier potassium channel isolated by expression cloning.
