Homing in on Endogenous Badnaviral Elements: Development of Multiplex PCR-DGGE for Detection and Rapid Identification of Badnavirus Sequences in Yam Germplasm

Frontiers in Plant Science, 2022
Viruses of the genus Badnavirus (family Caulimoviridae) are double-stranded DNA-reverse transcribing (dsDNA-RT) plant viruses and have emerged as serious pathogens of tropical and temperate crops globally.

The Elusive Fraction of Marine Plankton Diversity: Size, Abundance and Taxonomic Composition of 0.2 μm‐Filterable Prokaryotes Across Three Contrasting Coastal Environments

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The existence of prokaryotes escaping filtration through 0.2‐μm filters has been known for decades. Such ‘filterable’ prokaryotes (hereafter ‘FP’) might include true ultra‐small groups (i.e., ultramicrobacteria), but also cells that miniaturize temporally as a physiological strategy to persist under unfavourable conditions, representing a ...

PHYLOGENETIC ANALYSIS OF BACTERIAL COMMUNITIES IN PANCURAN 7 BATURRADEN HOT SPRING [PDF]

, 2006
The diversity of the bacterial communities supported by culturing and capturing through 0.2 m-pore-size filter was studied. The Pancuran 7 hot spring has temperature at around 52°C and pH 7.

Dynamics of lactic acid bacteria populations in Rioja wines by PCR-DGGE, comparison with culture-dependent methods

, 2013
Lactic acid bacteria populations of red wine samples from industrial fermentations, including two different vinification methods were studied. For this investigation, polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis ...

Mutations in the low density lipoprotein receptor gene of familial hypercholesterolemic patients detected by denaturing gradient gel electrophoresis and direct sequencing.

Journal of Lipid Research, 1995
Familial hypercholesterolemia (FH) results from mutations in the low density lipoprotein receptor (LDLR) gene. We applied denaturing gradient gel electrophoresis (DGGE) to screen for sequence variations in the coding and splice site consensus sequences ...

Comparing Freshwater eDNA With Conventional Survey Methods to Detect Vertebrate Biodiversity in a Malagasy Tropical Rainforest

Environmental DNA, Volume 8, Issue 3, May–June 2026.
This study compares the efficacy of conventional surveys of vertebrate taxa to eDNA metabarcoding of freshwater samples from a tropical rainforest ecosystem in the Makira Forest Protected Area (MFPA), Madagascar. We demonstrate high but taxa‐varying efficacy of eDNA metabarcoding detections, reinforcing its use as a complementary biodiversity survey ...

16S rRNA PCR-DGGE based bacterial community structure in activated sludge systems / Ang Pey Pey [PDF]

, 2012
We studied bacterial community structure in three different sewage treatment plants (STPs), namely STP 1, 2 and 3, in Klang Valley. STP 1, 2 and 3 were located in residential, commercial and light-industrial areas, respectively.

Comparison of DNA extraction kits for PCR-DGGE analysis of human intestinal microbial communities from fecal specimens

Nutrition Journal, 2010
Background The influence of diet on intestinal microflora has been investigated mainly using conventional microbiological approaches. Although these studies have advanced knowledge on human intestinal microflora, it is imperative that new methods are ...

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

Journal 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 ...
