Knowledge and Management of Aquatic Ecosystems, 2006 There are only very limited reports about the occurrence of the crayfish plague in Czechia. In recent years, mass mortalities of Astacus spp. with symptoms of possible crayfish plague were noticed in three streams in the country two in Central Bohemia (

Convergence of retrotransposons in oomycetes and plants [PDF]
Mobile DNA, 2017 Retrotransposons comprise a ubiquitous and abundant class of eukaryotic transposable elements. All members of this class rely on reverse transcriptase activity to produce a DNA copy of the element from the RNA template. However, other activities of the retrotransposon-encoded polyprotein may differ between diverse retrotransposons.

Biological effects of oomycetes elicitins [PDF]
Plant Protection Science, 2020 Successful plant defence responses to pathogen challenges are based on fast and specific pathogen recognition and plant reaction mechanisms. Elicitins, proteinaceous elicitors secreted by the Phytophthora and Pythium species, were first described in Phytophthora culture filtrates as proteins able to induce a hypersensitive response (HR) and resistance ...

Calcium Signaling in Oomycetes: An Evolutionary Perspective [PDF]
Frontiers in Physiology, 2016 Oomycetes are a family of eukaryotic microbes that superficially resemble fungi, but which are phylogenetically distinct from them. These organisms cause major global economic losses to agriculture and fisheries, with representative pathogens being Phytophthora infestans, the cause of late potato blight and Saprolegnia diclina, the instigator of ...

Biotic modulators of global change effects on plant communities
Biological Reviews, EarlyView.ABSTRACT Understanding and predicting future plant biodiversity and productivity is critical for prioritizing global change mitigation, conservation, and restoration efforts. One major challenge is that we know remarkably little about how interspecific interactions may modulate the effects of global change factors on diversity and productivity.

Phytophthora infestans has a plethora of phospholipase D enzymes including a subclass that has extracellular activity [PDF]
, 2011 In eukaryotes phospholipase D (PLD) is involved in many cellular processes. Currently little is known about PLDs in oomycetes. Here we report that the oomycete plant pathogen Phytophthora infestans has a large repertoire of PLDs divided over six ...

OOMYCETES: LAGENIDIUM GIGANTEUM
Journal of the American Mosquito Control Association, 2007 Lagenidium giganteum is a facultative parasite of mosquito larvae that initiates infection by production of biflagellate zoospores that selectively recognize and attach to larval cuticle. Following penetration of the cuticle, the parasite proliferates within the host, killing it within 24-60 h.
