Wounds}, doi = {}, url = {http://}, pmid = {}, journal = {Fungal Diversity}, volume = {}, number = {}, pages = {}, abstract = {Commercial plantations of Eucalyptus species have been established in South China especially during the past twenty years to meet the needs of a rapidly growing national economy. As part of a survey of fungal diseases affecting Eucalyptus species in South China, Ceratocystis species were collected in commercial Eucalyptus plantations in the GuangDong Province. The aims of this study were to identify the Ceratocystis isolates and to test their pathogenicity on Eucalyptus. The most aggressive isolates were also used to screen different species and clones of Eucalyptus for susceptibility to infection under field conditions. The fungi were identified based on morphology and through comparisons of DNA sequence data of the ITS, partial β-tublin and TEF-1 gene regions. Morphological and DNA sequence comparisons indicated that isolates collected from Chinese Eucalyptus plantations represent two species, C. acaciivora in the C. fimbriata s.l. species complex and a previously undescribed species belonging to the C. moniliformis s.l. species complex, for which the name C. chinaeucensis sp. nov. is provided. In pathogenicity trials, both C. acaciivora and C. chinaeucensis gave rise to lesions on wounded Eucalyptus trees, and the former fungus was most pathogenic. Differences were also observed in the responses of different Eucalyptus clones to inoculation and this could be useful in reducing disease, if C. acaciivora should emerge as a pathogen in the future.} }
