Abstract

During extensive surveys of Phytophthora diversity, 14 new species were detected in natural ecosystems in Chile, Louisiana, Sweden, Ukraine, Vietnam and Indonesia. Multigene phylogeny based on the nuclear LSU, rpl10, ITS, ßtub, enl, hsp90, tef-1α, ras-ypt1 and tigA and the mitochondrial cox1, nadh1 and rps10 gene sequences demonstrated that they belong to phylogenetic Clade 10 which is structured into three subclades. Subclades 10a and 10b comprise soil- and waterborne species with nonpapillate sporangia and variable breeding systems, including the known P. afrocarpa, P. gallica and P. intercalaris and the new P. ludoviciana, P. procera, P. pseudogallica, P. scandinavica, P. subarctica, P. tenuimura, P. tonkinensis and P. ukrainensis. In contrast, all species in Subclade 10c are airborne with papillate sporangia and homothallic breeding system, including the known P. boehmeriae, P. kernoviae and P. morindae and the new P. celebensis, P. chilensis, P. javanensis, P. multiglobulosa, P. pseudochilensis and P. pseudokernoviae. All new species differed from each other and from related species by a unique combination of morphological characters, the breeding system, cardinal temperatures and growth rates. The biogeography and evolutionary history of Clade 10 are discussed and the hypothesis put forward that the extant subclades originate from early divergences of pre-Gondwanan ancestors (>175 Mya) into water-/soilborne and airborne lineages which during their global spread experienced multiple allopatric and sympatric radiations.
