The cell walls of green algae: a journey through evolution and diversity

open access: yesFrontiers in Plant Science, 2012
The green algae represent a large group of morphologically diverse photosynthetic eukaryotes that occupy virtually every photic habitat on the planet. The extracellular coverings of green algae including cell walls are also diverse.

Capillary Electrophoresis Single-Strand Conformational Polymorphisms as a Method to Differentiate Algal Species

open access: yesJournal of Analytical Methods in Chemistry, 2015
Capillary electrophoresis single-strand conformational polymorphism (CE-SSCP) was explored as a fast and inexpensive method to differentiate both prokaryotic (blue-green) and eukaryotic (green and brown) algae. A selection of two blue-green algae (Nostoc

The Utilization of Algae with the Aim to Increase the Fatty Acid Content in Muscle of Common Carp (Cyprinus carpio L.)

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The aim of this study was to evaluate the efficiency of feeds with the addition of various algae and cyanobacteria. Common carp (average body mass of 19.6 ± 3.49 g) were randomly divided into 4 groups and fed a commercial feed (control group), the same ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
