The analysis of the control region of human mitochondrial genome (mtDNA) especially hypervariable regions I (HVI) and II (HVII) segments have been proven to be useful for human identification. For forensic application of mtDNA profiling in Malaysia, a comprehensive database on both HVI and HVII regions are essential. In order to identify polymorphic positions and to determine their frequency in the Malay population, mtDNA HVI and HVII regions of 103 maternally unrelated individuals were amplified ,sequenced and compared with Cambridge reference sequence (CRS). Sequence comparison led to the identification of a total of 446 and 604 location polymorphisms in mtDNA HVI and HVII regions respectively. This polymorphisms defined by 88 haplotypes (81 unique) in the HVI and 78 haplotypes (64 unique) in the HVII regions. In combined HVI and HVII defined 101 haplotypes (99 unique) was defined. In the HVII region All the individuals in HVII showed nucleotide transition event from A G at nucleotide position 073 and 263 and an insertion of cytosine (315.1C) at nucleotide position 315. The genetic diversity and probability of random match in combined HVI and HVII of 103 Malay individuals was found to be 0.9996 and 0.0101 respectively.Scientific World, Vol. 12, No. 12, September 2014, page 24-29

The 16S Rrna Gene

Microorganisms inhabiting saline environments are an interesting ecological model for the study of the adaptation of organisms to extreme living conditions and constitute a precious resource of enzymes and bioproducts for biotechnological applications. We analyzed the microbial communities in nine ponds with increasing salt concentrations (salinity range 4.9–36.0%) of the Saltern of Margherita di Savoia (Italy), the largest thalassohaline saltern in Europe. A deep-metabarcoding NGS procedure addressing separately the V5-V6 and V3-V4 hypervariable regions of the 16S rRNA gene of Bacteria and Archaea, respectively, and a CARD-FISH (catalyzed reporter deposition fluorescence in situ hybridization) analysis allowed us to profile the dynamics of microbial populations at the different salt concentrations. Both the domains were detected throughout the saltern, even if the low relative abundance of Archaea in the three ponds with the lowest salinities prevented the construction of the relative amplicon libraries. The highest cell counts were recorded at 14.5% salinity for Bacteria and at 24.1% salinity for Archaea. While Bacteria showed the greatest number of genera in the first ponds (salinity range 4.9–14.5%), archaeal genera were more numerous in the last ponds of the saltern (salinity 24.1–36.0%). Among prokaryotes, Salinibacter was the genus with the maximum abundance (~49% at 34.6% salinity). Other genera detected at high abundance were the archaeal Haloquadratum (~43% at 36.0% salinity) and Natronomonas (~18% at 13.1% salinity) and the bacterial “Candidatus Aquiluna” (~19% at 14.5% salinity). Interestingly, “Candidatus Aquiluna” had not been identified before in thalassohaline waters.

Abstract Surveys in Drosophila have consistently found reduced levels of DNA sequence polymorphism in genomic regions experiencing low crossing-over per physical length, while these same regions exhibit normal amounts of interspecific divergence. Here we show that for 36 loci across the genomes of eight Lycopersicon species, naturally occurring DNA polymorphism (scaled by locus-specific divergence between species) is positively correlated with the density of crossing-over per physical length. Large between-species differences in the amount of DNA sequence polymorphism reflect breeding systems: selfing species show much less within-species polymorphism than outcrossing species. The strongest association of expected heterozygosity with crossing-over is found in species with intermediate levels of average nucleotide diversity. All of these observations appear to be in qualitative agreement with the hitchhiking effects caused by the fixation of advantageous mutations and/or “background selection” against deleterious mutations.

Maternally inherited Wolbachia endosymbionts manipulate arthropod reproduction in various ways. In the butterfly Eurema mandarina , a cytoplasmic incompatibility-inducing Wolbachia strain w CI and the associated mtDNA haplotypes are known to originate from the sister species Eurema hecabe , which offered a good case study for microbe-mediated hybrid introgression. Besides w CI, some females with the Z0 karyotype harbour a distinct Wolbachia strain w Fem, which causes all-female production by meiotic drive and feminization. We report that a considerable proportion of E. mandarina females (65.7%) were infected with both w CI and w Fem (CF) on Tanegashima Island. While females singly infected with w CI (C) produced offspring at a 1 : 1 sex ratio, CF females produced only females. Although Z-linked sequence polymorphism showed no signs of divergence between C and CF females, mtDNA split into two discrete clades; one consisted of C females and the other CF females, both of which formed a clade with E. hecabe but not with uninfected E. mandarina . This suggests that CF matrilines also, but independently, experienced a selective sweep after hybrid introgression from E. hecabe . Distinct evolutionary forces were suggested to have caused C and CF matrilines to diverge, which would be irreversible because of the particular phenotype of w Fem.
