A new downy-mildew of the Rosaceae: Peronospora oblatispora sp. nov. (Chromista, Peronosporales)
Nova Hedwigia, 2007Peronospora oblatispora sp. nov., parasitic on Potentilla chrysantha, P. paradoxa, P. supina and Aphanes microcarpa, is described from 11 specimens collected in France, Korea and Romania. By its oblate conidia it differs morphologically from both P. sparsa and P. potentillae.

Evolutionary analysis revealed the horizontal transfer of the Cyt b gene from Fungi to Chromista
Molecular Phylogenetics and Evolution, 2014In this study, the cytochrome b (Cyt b) amino acid sequences were analyzed in 50 organisms covering all 5 kingdoms of eukaryotes. Six conserved domains, i.e., heme bL binding sites, heme bH binding sites, Qo binding sites, Qi binding sites, the interchain domain interface, and the intrachain domain interface were found in all investigated sequences ...

Peronospora-like fungi (Chromista, Peronosporales) parasitic on Brassicaceae and related hosts
Nova Hedwigia, 2002The genus Peronospora is emended and its type species, P. rumicis, is redescribed and illustrated. A new genus, Hyaloperonospora Constant., with 6 new combinations (H. floerkeae, H. lepidii-perfoliati, H. lunariae, H. niessleana, H.

The doves and pigeons constitute a taxonomic group (Columbiformes: Columbidae) of granivorous and frugivorous birds with a worldwide distribution. The current work aims to describe morphologically and molecularly a new protozoan from white-tipped doves Leptotila verreauxi Bonaparte, 1855 and grey-fronted doves Leptotila rufaxilla (Richard & Bernard,

Journal of Phycology, 2000
Chloroplasts in heterokont algae are surrounded by four membranes and probably originated from a red algal endosymbiont that was engulfed and retained by eukaryotic host. Understanding how nuclear‐encoded chloroplast proteins are translocated from the cytoplasm into the chloroplast across these membranes could give us some insights about how the ...

SUMMARYThe psychrophilic freshwater alga Hydrurus foetidus (Villars) Trevisan has previously resisted laboratory culturing in liquid media. We investigated the use of microbiological techniques adapted to specific requirement for low temperature and high turbulence of the alga. We found that successful culturing required cleaning steps, where pieces of

Plasmoverna gen. nov., and the taxonomy and nomenclature of Plasmopara (Chromista, Peronosporales)
Taxon: international journal of plant taxonomy, phylogeny and evolution, 2005After a review of the taxonomy and nomenclature of Plasmopara, it is concluded that this genus contains at least two groups of fungi that can be differentiated on both morphological and molecular grounds. In order to avoid numerous nomenclatural changes, the genus Plasmoverna with seven new combinations (Pv. pygmaea, Pv. alpina, Pv. anemones-dichotomae,

Structural features of the amino acid sequences of Chromista nucleolin-like proteins
Abstract Nucleolins are multifunctional proteins localized in the centrosome and nucleus and involved in the processes of microtubule nucleation. Their structure is highly conserved in organisms that are evolutionarily distant from each other.Darya P. Petrova +2 more
