Abstract

Many species in the Cryphonectriaceae cause diseases of trees, including those in the genera Eucalyptus and Syzygium. During disease surveys on these trees in South China, fruiting structures typical of fungi in the Cryphonectriaceae and associated with dying branches and stems were observed. Morphological comparisons indicated that these fungi were distinct from the well-known Chrysoporthe deuterocubensis, also found on these trees in China. The aim of this study was to identify the fungi and evaluate their pathogenicity to Eucalyptus clones/species and Syzygium cumini. Three morphologicaly similar fungal isolates collected previously from Indonesia were also included in the study. Isolates were characterized based on comparisons of their morphology and DNA sequence data for the partial LSU and ITS nuclear ribosomal areas, β-tubulin, and TEF-1α gene regions. Following glasshouse trials to select virulent isolates, field inoculations were undertaken to screen different commercial Eucalyptus clones/species and S. cumini trees for susceptibility to infection. Phylogenetic analyses showed that the Chinese isolates and those from Indonesia reside in a clade close to previously identified South African Celoporthe isolates. Based on morphology and DNA sequence comparisons, four new Celoporthe spp. were identified, including C. syzygii, C. eucalypti, C. guangdongensis and C. indonesiensis. Field inoculations indicated that the three tested Chinese Celoporthe spp., namely C. syzygii, C. eucalypti and C. guangdongensis, are pathogenic to all tested Eucalyptus and S. cumini trees. Significant differences in the susceptibility of the inoculated Eucalyptus clones/species suggest that it will be possible to select disease tolerant planting stock for forestry operations in the future.
