"During the course of investigation on pythiaceous fungi occurring in the burgundian vineyards, a new species of Pythium has been isolated. This oomycete is characterised by its non-proliferating and non sporulating type of sporangia (hyphal bodies), smooth walled oogonia that have hypogynous, monoclinous or at times diclinous antheridia, and smooth walled oospores that can have up to 3 per oogonia. The oomycete produces appressoria from which sexual structures may originate which is a rare feature for the genus. Sequence analyses of its ITS regions of rDNA show a close relationship with P. debaryanum and P. violae but has its own distinguishing characteristics. Morphological and molecular features of this isolate justify its description as a new species: Pythium viniferum. When grown together with Botrytis cinerea, the causal agent of the grey mould disease of grapevine, this oomycete shows a pronounced antagonism and suppresses its growth. Since it is not pathogenic to the grapevine it can be used as a bio-control agent. Morphology, antagonism with Botrytis cinerea, and the phylogenetic position of the new species are discussed here." . "2008"^^ . . . "2008"^^ . "Paul et al. (2008)" .
