“…In addition, the same fungus has been reported on Acacia spp. in Malaysia (Brawner et al, 2015) and on Eucalyptus trees in South China (Chen et al, 2013). The SSR markers used in this study should, in future, be screened on isolates from these countries to determine the genetic structure of additional populations.…”

“…Concern regarding the pathogen has increased in recent years, as it has been found on the native legume trees Prosopis cineraria (Ghaf) in Oman and Dalbergia sissoo (Shisham) in Pakistan (Al Adawi et al, 2013b). This species has also been reported on the widely planted A. mangium in South East Asian countries, including Indonesia (Tarigan et al, 2011) and Malaysia (Brawner et al, 2015), and on Eucalyptus species in South China (Chen et al, 2013). Isolates of Ceratocystis spp, which could represent the same species, have also been reported from Eucalyptus trees in Brazil and Punica granatum (pomegranate) in India (Harrington et al, 2014).…”

Highlights• In Oman and Pakistan, C. manginecans from native legumes are genetically identical to the clonal population from M. indica.• The data suggest a possible area of origin for C. manginecans in South East Asia, particularly Vietnam.• Microsatellite primers were designed, from the genome of C. manginecans, that can be used in a multiplex PCR approach. ABSTRACTThe fungal pathogen, Ceratocystis manginecans, has caused serious canker and wilt disease on Mangifera indica (mango), on legume tree species in Oman and Pakistan and on manginecans. Unlike the populations in Oman and Pakistan, relatively high levels of genetic variation were found for the isolates from Indonesia and Vietnam. The Vietnam population was significantly differentiated from the other populations and isolates from this area had the highest level of genetic diversity thus far encountered for the pathogen.

Wood‐rotting basidiomycetes are a minor component of fungal communities associated with Acacia hybrid trees grown for sawlogs in South Vietnam

Acacia hybrid (Acacia mangium × Acacia auriculiformis) clones are widely planted in Vietnam with a total of approximately 400,000 ha to meet the demand for pulpwood, sawn timber and wood chip exports. Silvicultural techniques such as pruning and thinning have been applied to improve productivity and sawlog quality of Acacia hybrid plantations. However, those techniques may also create opportunities for wood decay fungi to enter the Acacia hybrid stems through wounds and cause stem defects that reduce sawlog quality and the value of the plantation. The presence of fungal decay agents in Acacia hybrid trees was examined in two Vietnamese plantations. In July 2011, just prior to a second thinning, discoloured wood samples were taken from a three-year-old Acacia hybrid plantation at Phan Truong Hai for the isolation of fungi. In July 2012, approximately 18 months after pruning and thinning treatments, discoloured wood samples were taken from a three-year-old Acacia hybrid plantation at Nghia Trung for the isolation of fungi. DNA sequencing of the rDNA ITS identified the isolates. In May 2015, approximately 4 years after thinning and fertilizer treatments, discoloured and decayed wood samples were taken from the above (7-year-old) Acacia hybrid plantation at Phan Truong Hai for fungal identification.DNA was extracted directly from discoloured and decayed wood samples and fungal rDNA ITS amplicons sequenced on a Roche 454 sequencer. The results showed that silvicultural treatments did not affect the fungal communities associated with discoloured and decayed wood of Acacia hybrid plantation at Phan Truong Hai. A total of 135 fungal species or OTUs (operational taxonomic units) were identified, including 82 members of Ascomycota and 52 Basidiomycota.

“…In recent years, fungal diseases, such as Ganoderma and Ceratocystis, have caused significant death in tropical Acacia plantations in Indonesia. Recent research has enabled rapid screening of planting stock for variations in tolerance and/or susceptibility to G. philippi (Gafur et al 2015), while preliminary trials on resistance and tolerance to Ceratocystis has indicated that the development of resistant breeds will be challenging (Brawner et al 2015).…”

The Australian Centre for International Agricultural Research (ACIAR) commissions collaborative agriculture, fisheries and forestry research projects in developing countries. Over a 30-year period, ACIAR has invested over AUD 100 million to fund 150 forestry projects and activities in 29 countries, with most of these projects implemented in Indonesia, Vietnam and Papua New Guinea. This article describes the approach that ACIAR uses to develop and implement projects, and reviews the nature of the ACIAR Forestry Program and its achievements during each decade of its existence. About three-quarters of the research projects have focused on aspects of smallholder and community forestry systems. The findings from a series of independent impact assessment studies, which demonstrate generally high returns on the forestry research investment, are reviewed and some examples of different categories of impacts from the research projects are discussed.
