Adaptive genomic plasticity in large-genome, broad-host-range vibrio phages

Charles Bernard, Yannick Labreuche, Carine Diarra, Pauline Daszkowski, Karine Cahier, David Goudenège, Martin G Lamarche, Gregory B Whitfield, Manon Lang, Jeffrey Valencia, Justine Groseille, Damien Piel, Yan-Jiun Lee, Peter Weigele, Yves V Brun, Eduardo P. C. Rocha, Frédérique Le Roux

The host range of a bacteriophage-the diversity of hosts it can infect-is central to understanding phage ecology and applications. Whereas most well-characterized phages have narrow host ranges, broad-host-range phages represent an intriguing component of marine ecosystems. The genetic and…

Multiple, diverse endogenous giant virus elements within the genome of a brown alga

Dean Mckeown, Alexandre Cormier, Declan C Schroeder, Arnaud Couloux, Nachida Tadrent, J. Mark Cock, Erwan Corre

Endogenous viral elements (EVEs) have been found in diverse eukaryotic genomes. These elements are particularly frequent in the genomes of brown algae (Phaeophyceae) because these seaweeds are infected by viruses (Phaeovirus) of the phylum Nucleocytoviricota (NCV) that are capable of inserting into…

Exploration of the extracellular matrix of the red alga Chondrus crispus reveals unprecedented insights into carrageenan structures

David Ropartz, Adrien Lissarrague, Murielle Jam, Diane Jouanneau, Bastien Annic, Sophie Le Gall, Mathieu Fanuel, Stacy Krueger-Hadfield, Myriam Valéro, Mirjam Czjzek, Hélène Rogniaux, Cécile Hervé

Carrageenans are major gel forming polysaccharides in the extracellular matrix of the red macroalga Chondrus crispus. These galactans are made of linear chains of repetitive disaccharide motifs based on d-galactose residues alternately linked by β-1,4 and α-1,3 glycosidic bonds. A definite number…
