Olpidiopsis bostrychiae sp. nov.: an endoparasitic oomycete that infects Bostrychia and other red algae (Rhodophyta)

Intracellular eukaryotic pathogens in brown macroalgae in the Eastern Mediterranean, including LSU rRNA data for the oomycete Eurychasma dicksonii

“…Two of the pathogens covered here have so far scarcely been described in the literature. Other authors are also contributing to filling this knowledge gap about seaweed pathogens worldwide (West et al 2006, Sekimoto et al 2009, Klochkova et al 2012. Their work and ours provide circumstantial evidence that hints that there may be an equal prevalence, and possibly equal ecological importance, of seaweed parasites in warm seas compared to comparatively better-known temperate ecosystems.…”

“…However, currently sequence information on different marker genes is in many instances restricted and fragmentary, which especially holds true for the basal oomycetes (e.g. Hakariya et al 2009, Muraosa et al 2009, Sekimoto et al 2009 Sparrow 1960). Members of the Sphacelariales show apical growth patterns (Katsaros 1995).…”

A revaluation of algal diseases in Korean Pyropia (Porphyra) sea farms and their economic impact

“…Olpidiopsis is an obligate endoparasite, infecting many different species of Pyropia (Sekimoto et al 2008(Sekimoto et al , 2009. We recorded Olpidiopsis spp.…”

The Evolutionary Phylogeny of Oomycetes—Insights Gained from Studies of Holocarpic Parasites of Algae and Invertebrates

“…1.4c-e; Sekimoto et al, 2008a) and Olpidiopsis bostrychiae ( Fig. 1.4m; Sekimoto, 2008;Sekimoto et al, 2009) form a separate clade from the crustacean parasites, Haliphthoros and Halodaphnea (syn. Halocrusticida) (Fig.…”
