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.

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).

From microbes to mammals: Pond biodiversity homogenization across different land‐use types in an agricultural landscape

Ecological Monographs, Volume 92, Issue 3, August 2022., 2022
Abstract Local biodiversity patterns are expected to strongly reflect variation in topography, land use, dispersal boundaries, nutrient supplies, contaminant spread, management practices, and other anthropogenic influences. Contrary to this expectation, studies focusing on specific taxa revealed a biodiversity homogenization effect in areas subjected ...

Hemicellulose‐remodelling transglycanase activities from charophytes: towards the evolution of the land‐plant cell wall

The Plant Journal, Volume 108, Issue 1, Page 7-28, October 2021., 2021
Significance Statement Transglycanase enzymes remodel land‐plant cell walls, enabling wall restructuring. Unfortunately, comparable enzymes in charophytes (the land plants’ closest algal relatives) are little known, limiting our understanding of the ‘alga to land plant’ transition.

Calcium and pH interaction limits bloom formation and expansion of a nuisance microalga

Limnology and Oceanography, Volume 66, Issue 9, Page 3523-3534, September 2021., 2021
Abstract Microalgal range expansions are increasing in frequency and magnitude but generally remain unnoticed until mass development occurs. Gonyostomum semen is a freshwater raphidophyte that causes nuisance blooms in lakes and has recently expanded its distribution across Europe. G.

Cultivation and Photophysiological Characteristics of Desmids in Moderately Saline Aquaculture Wastewater

Journal of Phycology, Volume 57, Issue 3, Page 926-941, June 2021., 2021
Although desmids typically inhabit freshwater environments characterized by low amounts of nutrients and low salinity, several desmid species have been recorded in eutrophic waters, indicating their adaptation to elevated pollution and conductivity.
