Pestalotiopsis and allied genera from Camellia, with description of 11 new species from China
Abstract A total of 124 Pestalotiopsis-like isolates associated with symptomatic and asymptomatic tissues of Camellia sinensis and other Camellia spp. from eight provinces in China were investigated. Based on single- and multi-locus (ITS, TEF, TUB2) phylogenies, as well as morphological characters,...

| Sumario: | Abstract A total of 124 Pestalotiopsis-like isolates associated with symptomatic and asymptomatic tissues of Camellia sinensis and other Camellia spp. from eight provinces in China were investigated. Based on single- and multi-locus (ITS, TEF, TUB2) phylogenies, as well as morphological characters, host associations and geographical distributions, they were classified into at least 19 species in three genera, i.e. Neopestalotiopsis, Pestalotiopsis and Pseudopestalotiopsis. Eight novel species in Pestalotiopsis and three novel species in Pseudopestalotiopsis were described. Our data suggested that the currently widely used loci in Pestalotiopsis-like genera do not consistently provide stable and sufficient resolution tree topologies, especially for Neopestalotiopsis. Moreover, the number, branch pattern and length of the conidial basal appendages were revealed to be phylogenetically informative characters in Pestalotiopsis. |
