Effect of legume-cereal mixtures on the diversity of bacterial communities in the rhizosphere

open access: yesPlant, Soil and Environment, 2012
Aboveground plant diversity is known to influence belowground diversity and ecosystem processes. However, there is little knowledge of soil microbial succession in legume-grass mixtures.

Fingerprinting sequence variation in ribosomal DNA of parasites by DGGE [PDF]

open access: yesMolecular and Cellular Probes, 1996
Although there is a tendency for rDNA genes within a species to maintain sequence homogeneity, there can be significant levels of variation among rDNA repeat sequences within populations or individuals of a species as a consequence of mutation mechanisms.

Emulsion PCR (ePCR) as a Tool to Improve the Power of DGGE Analysis for Microbial Population Studies

open access: yesMicroorganisms, 2020
To the authors’ knowledge, this is the first report of the use of emulsion-Polymerase chain reaction (e-PCR) coupled with denaturing gradient gel electrophoresis (DGGE) analysis. In the present work the effectiveness of ePCR in improving the power of the

Testing of primers for the study of cyanobacterial molecular diversity by DGGE [PDF]

open access: yesJournal of Microbiological Methods, 2006
Denaturing Gradient Gel electrophoresis (DGGE) is a PCR-based technique which is widely used in the study of microbial communities. Here, the use of the three specific 16S rRNA cyanobacterial specific primers CYA359F, CYA781R(a) and CYA781R(b) on the assessment of the molecular diversity of cyanobacterial communities is examined.

Molekulski pristopi pri raziskavah arbuskularne mikorize

open access: yesActa Agriculturae Slovenica, 2009
Arbuskularna mikoriza se je razvila v koevoluciji s kopenskimi rastlinami. Čeprav predstavlja eno najbolj razširjenih simbioz na kopnem, še vedno obstajajo številna odprta vprašanja o biologiji arbuskularnih mikoriznih gliv ter njihovi ekološki vlogi v ...
