We have analysed nine autosomal STR loci (D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820) in Goud and Padmashali populations belonging to Chittoor and Cuddapah districts of Andhra Pradesh, India, respectively. This data was compared with the available data on Indian populations. Heterozygosity (H), power of discrimination (PD), probability exclusion (PE), typical paternity index (TPI), polymorphism information content (PIC), exact test with Bonferroni corrections and Arlequin analysis were carried out. Average heterozygosity observed in Goud and Padmashali populations were 0.82 and 0.81, respectively. Similarly, PD, PE, TPI and PIC have been found to be almost same between these two populations. Overall data analysis suggests the existence of sub-structuring in Indian populations.
This paper presents the results of a study on the influence of lead, copper, manganese and cadmium on DNA integrity in plant cells. Plants, as biological indicators, can measure the potential effects of pollutants when they are used to measure effects of heavy metals. The genotoxicity of heavy metals in kidney-bean (Phaseolus vulgaris) seedlings was subjected to RAPD (random amplified polymorphic DNA) analysis. An RAPD 'fingerprinting' technique was used to detect DNA damage in the kidney-bean seedlings treated with two selected heavy metals at concentrations of 150 and 350 mg x l(-1). Polymorphisms became evident as the presence and/or absence of DNA fragments in treated samples compared with the untreated one. At 350 mg x l(-1), a high number of both missing bands and new amplified fragment were observed. Results suggested that a qualitative measure reflecting changes in RAPD profiles were significantly affected at higher concentrations (350 mg x l(-1)) of the tested heavy metals. A total of 467 RAPD fragments in RAPD profiles were detected by using six random primers (decamers) and 224 of these fragments showed polymorphism. There was a distinct distance between the band patterns of treated plants and the control samples when the cluster method was applied. In addition, the result derived from numerical analysis revealed a considerable distance between the band pattern of the plant samples treated with 350 mg x l(-1) heavy metals and the control sample. Finally, a comparison between untreated and treated genomes shows that RAPD analysis can be used to evaluate how the environmental pollutants modify the structure of DNA in living organisms.
Allele frequencies, together with some parameters of forensic interest for 10 STRs (D3S1358, vWA, D16S539, D2S1338, D8S1179, D21S11, D18S51, D19S433, TH01 and FGA) were estimated from 201 unrelated individuals originating from southern Tunisia. Significant deviation from Hardy-Weinberg equilibrium was observed for only one marker. Comparative analyses between our population data and other populations showed that only markers D3S158, vWA and FGA were homogenous among populations. The combination of these 10 STR loci provide a powerful tool for forensic identification in Tunisian population.
