Towards understanding the extensive diversity of protein N-glycan structures in eukaryotes. [PDF]

Biol Rev Camb Philos Soc, 2022
ABSTRACT N‐glycosylation is an important post‐translational modification of proteins that has been highly conserved during evolution and is found in Eukaryota, Bacteria and Archaea. In eukaryotes, N‐glycan processing is sequential, involving multiple specific steps within the secretory pathway as proteins travel through the endoplasmic reticulum and ...

<i>Vampyrella crystallifera</i> sp. nov., an Amoeba That Dissolves Entire Algal Cells at a Remarkable Speed. [PDF]

Ecol Evol
The new vampyrellid amoeba Vampyrella crystallifera inhabits wet Sphagnum plants in temperate moorlands. Unlike its congeners, it engulfs entire algal cells and breaks them down at a fascinating speed. This represents a feeding habit that was unexpected for the genus Vampyrella and showcases the exceptional diversity of predator–prey interactions found

The vampyrellid amoeba Strigomyxa ruptor gen. et sp. nov. and its remarkable strategy to acquire algal cell contents. [PDF]

Ecol Evol
The new vampyrellid amoeba Strigomyxa ruptor phagocytizes algal cells and opens them internally to extract the cell contents. Afterward, the algal cell walls are discarded through a “waste vacuole.” This sophisticated feeding strategy, here termed “internal protoplast extraction and cell wall regurgitation,” exemplifies the extraordinary complexity of ...

Genetic and morphological variation in the genus Zygogonium (Zygnematophyceae, Charophyta) from localities in Europe and North America and description of Z. angustum, sp. nov. [PDF]

J Phycol
Abstract The globally distributed genus Zygogonium exhibits a narrow environmental range, with 19 morphologically described species. Its molecular characterization is poor, based on a single accession of the type species Z. ericetorum from Austria.

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems. [PDF]

Mol Ecol Resour
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

NEW RECORDS FOR THE TURKISH FRESHWATER ALGAL FLORA IN TWENTY FIVE RIVER BASINS OF TURKEY, PART VI: CHAROPHYTA

Trakya University Journal of Natural Sciences, 2021
Although planktonic algae are a basic component of freshwater ecosystems, studies on their diversity and species distribution are still not in satisfactory numbers. This study aims to contribute to Turkish freshwater algal flora particularly with the new

Electroporation‐based delivery of proteins in Penium margaritaceum and other zygnematophycean algae

Physiologia Plantarum, Volume 175, Issue 6, November/December 2023., 2023
Abstract Zygnematophycean algae represent the streptophyte group identified as the closest sister clade to land plants. Their phylogenetic position and growing genomic resources make these freshwater algae attractive models for evolutionary studies in the context of plant terrestrialization.

The cell walls of different Chara species are characterized by branched galactans rich in 3‐O‐methylgalactose and absence of AGPs

Physiologia Plantarum, Volume 175, Issue 4, July/August 2023., 2023
Abstract Streptophyte algae are the closest relatives to land plants; their latest common ancestor performed the most drastic adaptation in plant evolution around 500 million years ago: the conquest of land. Besides other adaptations, this step required changes in cell wall composition.

Comparative study of algal community in African sharptooth catfish (Clarias gariepinus, Burchell 1822) and Nile tilapia (Oreochromis niloticus, Linnaeus 1758) farming ponds

Aquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 149-164, April 2023., 2023
In the fish farming station, algae specific richness varies according to the water collection point (rearing pond, evacuation canal and decantation pond). Algae contribute differentially to fish diets: biomass is mostly used by Nile Tilapia (herbivorous) than African catfish (omnivorous).
