High diversity of Phytophthora species in natural ecosystems and nurseries of P...
Horta Jung, Marília; Maia, Cristiana; Mora-Sala, Beatriz; Abad-Campos, Paloma; Schena, Leonardo; Mosca, Saveria; Carella, Giuseppe; Moricca, SalvatoreBetween 2010 and 2015, an extensive survey of Phytophthora diversity was performed across Portugal. Baiting and direct isolation tests obtained 48 Phytophthora taxa in 62 of 70 forest stands (89%) from 148 of 302 rhizosphere soil samples (49%) and 25 of 29 tree species (86%), and from bark cankers of Alnus lusitanica and Fagus sylvatica ; from 33 of 34 rivers and forest streams (97%); and in 12 of 13 forest nur...
Diversity of Phytophthora species in Valdivian rainforests and association with...
Jung, Thomas; Durán, Alvaro; Stowasser, Eugenio Sanfuentes von; Schena, Leonardo; Mosca, Saveria; Fajardo, Sebastian; González, MarielaThe Valdivian rainforest, one of the global hotspots of biodiversity, is a temperate rainforest originating as a Tertiary relic from the supercontinent Gondwana. In November 2014, a survey of Phytophthora diversity was performed in 13 natural forest stands and 20 forest streams and rivers in two protected areas near Valdivia and in a temperate montane forest in the Concepción area. One planted stand each of the...
Multiple new cryptic pathogenic Phytophthora species from Fagaceae forests in A...
Jung, Thomas; Horta Jung, Marília; Cacciola, Santa Olga; Cech, Thomas; Bakonyi, Jozsef; Seress, Diana; Mosca, Saveria; Schena, LeonardoDuring surveys of Phytophthora diversity in natural and semi-natural Fagaceae forests in Austria, Italy and Portugal, four new cryptic species were isolated from rhizosphere soil samples. Multigene phylogeny based on nuclear ITS, beta-tubulin and HSP90 and mitochondrial cox1 and NADH1 gene sequences demonstrated that two species, P. tyrrhenica and P. vulcanica spp. nov., belong to phylogenetic Clade 7a, while t...
