Six new Phytophthora species from ITS Clade 7a including two sexually functiona...
Jung, Thomas; Horta, Marília; Scanu, B.; Seress, D.; Kovacs, G. M.; Maia, Cristiana; Perez-Sierra, A.; Chang, T. -T.; Chandelier, A.; Heungens, K.During a survey of Phytophthora diversity in natural ecosystems in Taiwan six new species were detected. Multigene phylogeny based on the nuclear ITS, beta-tubulin and HSP90 and the mitochondrial cox1 and NADH1 gene sequences demonstrated that they belong to ITS Clade 7a with P. europaea, P. uniformis, P. rubi and P. cambivora being their closest relatives. All six new species differed from each other and from ...

Jung, Thomas; Chang, T. T.; Bakonyi, J.; Seress, D.; Perez-Sierra, A.; Yang, X.; Hong, C.; Scanu, B.; Fu, C. H.; Hsueh, K. L.; Maia, CristianaIn 2013 a survey of Phytophthora diversity was performed in 25 natural and seminatural forest stands and 25 rivers in temperate montane and subtropical lowland regions of Taiwan. Using baiting assays, 10 described species and 17 previously unknown taxa of Phytophthora were isolated from 71.5% of the 144 rhizosphere soil samples from 33 of 40 tree species sampled in 24 forest stands, and from 19 rivers: P. capen...
Widespread Phytophthora infestations in European nurseries put forest, semi-nat...
Jung, Thomas; Orlikowski, L.; Henricot, B.; Abad-Campos, P.; Aday, A. G.; Aguin Casal, O.; Bakonyi, J.; Cacciola, S. O.; Cech, T.; Chavarriaga, D.An analysis of incidence of Phytophthora spp. in 732 European nurseries producing forest transplants, larger specimen trees, landscape plants and ornamentals, plus 2525 areas in which trees and shrubs were planted, is presented based on work conducted by 38 research groups in 23 European countries between 1972 and 2013. Forty-nine Phytophthora taxa were recorded in 670 nurseries (91.5%); within these nurseries,...
