Calcium Signaling in Oomycetes: An Evolutionary Perspective.

ABSTRACT: 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 "cotton molds" in fish. As in all eukaryotes, cytoplasmic Ca(2+) is a key second messenger in oomycetes, regulating life-cycle transitions, controlling motility and chemotaxis and, in excess, leading to cell-death. Despite this, little is known about the molecular mechanisms regulating cytoplasmic Ca(2+) concentrations in these organisms. Consequently, this review analyzed the presence of candidate calcium channels encoded within the nine oomycete
