GENETIC EXCHANGES OF INTEINS BETWEENPRASINOVIRUSES(PHYCODNAVIRIDAE)

Evolution; International Journal of Organic Evolution, 2013
Phylogenetic diversity in the Phycodnaviridae (double-stranded DNA viruses infecting photosynthetic eukaryotes) is most often studied using their DNA polymerase gene (PolB). This gene and its translated protein product can harbor a selfish genetic element called an "intein" that disrupts the sequence of the host gene without affecting its activity ...

Entry of the DNA virus, Ectocarpus fasciculatus virus type 1 (Phycodnaviridae), into host cell cytosol and nucleus

Phycological Research, 2002
SUMMARY The process by which Ectocarpus fasciculatus virus type 1 (EfasV-1) infects zoospores of its brown algal host was studied by electron microscopy. Upon virus attachment to the target cell, the integral membrane component of the viral capsid fuses with the host plasma membrane, and the 140-nm viral DNA-protein core enters the cytosol. Within 5

Phycodnaviridae– large DNA algal viruses

Archives of Virology, 2002
Members and prospective members of the family Phycodnaviridae are large icosahedral, dsDNA (180 to 560 kb) viruses that infect eukaryotic algae. The genomes of two phycodnaviruses have been sequenced: the 331 kb genome of Paramecium bursaria chlorella virus (PBCV-1) and more recently, the 336 kb genome of the Ectocarpus siliculosus virus (EsV-1). EsV-1

Structural analyses ofPhycodnaviridaeandIridoviridae

Acta Crystallographica Section D Biological Crystallography, 2003
The Phycodnaviridae, Iridoviridae and related viruses, with diameters of 1500-2000 A, are formed from large trigonal arrays of hexagonally close-packed capsomers forming the faces of icosahedra [Yan et al. (2000), Nature Struct. Biol. 7, 101-103; Nandhagopal et al. (2002), Proc. Natl Acad. Sci. USA, 99, 14758-14763]. Caspar and Klug predicted that such

Studien zur Funktion von Kaliumkanälen aus Viren eukaryotischer Algen (Phycodnaviridae)

2008
Two distantly related algal viruses of the family Phycodnaviridae encode K+ channel-like genes. Paramecium bursaria Chlorella virus encodes Kcv, the first known viral K+ channel protein. Kev, a second putative viral K+ channel was derived from the genome of Ectocarpus siliculosus virus (EsV-1).

Diversité des prasinovirus (phycodnaviridae) et contrôle par les facteurs environnementaux.

Les virus sont les entités les plus abondantes dans les océans et ces parasitoïdes interagissent avec chaque composante de la biosphère marine, soit par la sélection des communautés d'hôte, soit en influençant les cycles biogéochimiques. Cependant, l'impact des conditions environnementales sur ces assemblages viraux complexes est encore mal compris.
