The impact of different DNA extraction methods on the analysis of microbial diversity of oral saliva from healthy youths by polymerase chain reaction-denaturing gradient gel electrophoresis

open access: yesJournal of Dental Sciences, 2016
Background/purpose: Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE), as a conventional molecular technique, was utilized to analyze the diversity of oral microbiota.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1399-1420, May 2026.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

Environmental and Temporal Effects on Vocal Activity in a Nocturnal Primate: Implications for Passive Acoustic Monitoring

open access: yesAmerican Journal of Primatology, Volume 88, Issue 3, March 2026.
Passive acoustic monitoring of the Critically Endangered Nosy Be sportive lemur (Lepilemur tymerlachsoni) for two lunar cycles revealed that vocal activity (i.e., call rates) increased over a 4‐h sampling window starting at twilight. The lemurs also called more as temperature and moonlight increased, and called less when it rained.

Genetic diversity of plankton community as depicted by PCR-DGGE fingerprinting and its relation to morphological composition and environmental factors in lake donghu [PDF]

open access: yes, 2007
To collect information about the genetic diversity of the plankton community and to study how plankton respond to environmental conditions, plankton samples were collected from five stations representing different trophic levels in a shallow, eutrophic ...

Lactic acid bacteria and identification with PCR-DGGE

open access: yesInternational Journal of Biological Research, 2017
Lactic acid bacteria (LAB) are an important group in the industrially using microorganisms. The first pure cultures of bacteria was "Bacterium lactis" (probably Lactococcus lactis), obtained in 1873 by J. Lister. LAB are Gram-positive, non motile, non spore-forming, except Sporolactobacillus inulinus, catalase negative, microaerophilic or anaerobic ...

Patterns of Composition, Richness and Endemicity of Cyperaceae Across Open and Closed Habitats in Madagascar's Central Highlands

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We assessed Cyperaceae species composition, richness and endemicity across closed (forest), dry open (dry grasslands, rocky outcrops, bare dry soils), and wet open (marshes, swamps, wet grasslands, riparian areas) habitats in Isalo National Park and the Itremo Massif Protected Area, both in Madagascar's Central Highlands.

Visual representation of the DGGE fingerprints.

open access: yes, 2014
Each vertical line of pixels represents the DGGE lane of a single sample. Lower bin numbers correspond to the top of the DGGE gel. Higher relative intensities of DGGE bins are represented with darker pixels.

Denaturing Gradient Gel Electrophoresis (DGGE): A Rapid and Sensitive Technique to Screen Nucleotide Sequence Variation in Populations

open access: yesBioTechniques, 1999
We describe a rapid and sensitive method for the detection of nucleotide sequence variation that can be used for largescale screening of population markers.

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 2, Page 256-269, February 2026.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.
