To separate the unknown Streptomyces strains isolated from soil samples, the interspacer regions of 16S-23S rDNA of 14 isolates were amplified with PCR (polymerase chain reaction) and digested with three restriction endonucleases, namely, Bsp143I, HaeIII and MnlI. The restriction patterns were used for RFLP (restriction fragment length polymorphism) analysis. A dendrogram were constructed using...

Soil microbial diversity is an important index of agricultural productivity by enhancing soil quality. Present study employed the combination of several methodologies to examine genetic relationships among specific groups of bacteria and to characterize strains at the species level using molecular biotyping techniques. The present study is based upon 16SrDNA analysis for characterisation of bac...

In the present paper phylogenetic relationships of Muslim populations of Manipur and its genetic relations with Meitei and Naga tribe based on the morphogenetic traits have been attempted. Till date, no biological research has been reported regarding their phylogeny. Muslims with different castes shows differences in the distribution of these morpho-genetic traits, showing differences of ancest...

Eighteen varieties of sugar beet (Beta vulgaris L.), originating from various European countries, were compared in respect of peroxidase variability level. They were cultivated in the same experimental plot. The cultivars differed in ploidy level: one variety was tetraploid, three were diploid and 14 varieties were triploid. The cathodic peroxidase system is controlled by four independent genes...

Prunus spinosa, blackthorn, exists as wild populations that inhabit uncultivated uplands of Coruh Valley in the northeastern part of Turkey; the fruit is used to make preserves. We examined genetic diversity in wild-grown Prunus spinosa; 16 individual plants from wild populations of Coruh Valley were sampled and subjected to RAPD (random amplified polymorphic DNA) analysis. We tested 51 random ...

Nine Random Amplified Polymorphic DNA (RAPD) primers showing polymorphic bands were used to determine the genetic relatedness among and within single individual plants of Lupinus pilosus and used for the construction of the dendrogram and the similarity matrix. A total of 1112 bands were obtained, 219 of which were polymorphic. Similarity values among the studied single individuals of Lupinus p...

Aims: The aim of the study was to determine genetic diversity twenty four Boro rice landraces using genome specific twelve well known SSR markers.
 Study Design: Genomic DNA extraction, PCR amplification, Polyacrylamide gel electrophoresis (PAGE) and data analysis-these steps were followed perform research work. Data analysed with help following software; POWERMAKER version 3.25, AlphaEase...

Corylus mandshurica, also known as pilose hazelnut, is an economically and ecologically important species in China. In this study, ten polymorphic simple sequence repeat (SSR) markers were applied to evaluate the genetic diversity and population structure of 348 C. mandshurica individuals among 12 populations in China. The SSR markers expressed a relatively high level of genetic diversity (Na =...

Okra (Abelmoschus esculentus L.) is not only a nutrient-rich vegetable but also an important medicinal herb. Inter-simple sequence repeat (ISSR) markers were employed to investigate the genetic diversity and differentiation of 24 okra genotypes. In this study, the PCR products were separated by electrophoresis on 8% nondenaturing polyacrylamide gel and visualized by silver staining. The 22 ISSR...

BACKGROUND Earthworms are an ecosystem's engineers, contributing to a wide range of nutrient cycling and geochemical processes in the ecosystem. Their activities can increase rates of silicate mineral weathering. Their intestinal microbes usually are thought to be one of the key drivers of mineral degradation mediated by earthworms,but the diversities of the intestinal microorganisms which were...
