Chondrostereum Purpureum

The mitochondrial DNA (mtDNA) of Chondrostereum purpureum (Pers.:Fr.) Pouzar was extracted and purified, and the size ranged from 51.8 to 66.4 kb. One isolate each from British Columbia, Alberta, Finland, the Netherlands, and New Zealand were found to have identical BamHI mtDNA restriction patterns, resulting in a mitochondrial genome of 63.8 kb. An additional isolate from British Columbia and one from Switzerland had different banding patterns, however, resulting in mitochondrial genomes of 66.4 kb and 51.8 kb, respectively. A sequence-characterized amplified region (SCAR) assay, based on a polymerase chain reaction, was developed to rapidly screen a larger population of 84 isolates from North America, Europe, and New Zealand. Two SCARs, one encoding the NADH 4 gene (3 kb) and the second encoding the ATPase VI and cytochrome b genes (5.1 kb), were digested with 24 restriction enzymes. There were no polymorphisms in the NADH 4 containing SCAR, while a single polymorphism was detected by NsiI in the ATPase VI - cytochrome b containing SCAR. Two mitochondrial haplotypes that were distributed throughout the sample population were thus identified. The coancestry coefficient (<$Q7A0D00000010446D80BFFEFF88A524F5343905055B98C420120907B4DDA9ECB1F0>) for all subpopulations of the sample population was calculated to be 0.0353. The level of gene diversity in the mtDNA ofC. purpureum suggested that the chance introduction of novel mitochondrial genes following biological control applications of the fungus is relatively low.

Buddleja davidii is a perennial woody shrub that is highly invasive in many parts of the world including New Zealand This study was conducted to assess the potential for inundative biological control of this weed using Chondrostereum purpureum a wound invasive basidiomycete The fungus has been registered for woody weed control in Canada and the Netherlands and is present throughout New Zealand Mature B davidii shrubs planted at the Scion campus Rotorua were cut 30 cm from the ground and the cut surface of the stems was immediately inoculated with C purpureumcolonised malt extract agar (MEA) and sealed with Parafilm There were four replicate shrubs for each of three isolates and the control (inoculation with sterile MEA) One year following inoculation no fruiting bodies of C purpureum have been observed on the treated B davidii Although the inoculated stems appear dead most replicates have extensive epicormic shoot development and are forming coppices

Chondrostereum Purpureum

Chondrostereum purpureum is a basidiomycete fungus that is being investigated as an inundative biological control agent for invasive woody weeds This study was conducted to assess the susceptibility of seven species of weeds to C purpureum The species that were inoculated in this trial were broom (Cytisus scoparius) gorse (Ulex europeaus) buddleia (Buddleja davidii) Himalayan honeysuckle (Leycesteria formosa) hawthorne (Crataegus monogyna) poplar (Populus trichocarpa) and willow (Salix matsudana) Two isolates of C purpureum and a control were used and were each replicated 12 times All plants were potted and the trial took place under nursery conditions Mortality and canker size were measured 6 months after inoculation Data were analysed using SAS The highest mortality (50) was recorded for broom with one isolate but very little mortality was observed across the other species A highly significant weed by isolate interaction was observed with regards to lesion length with weed species susceptibility varying with respect to one of the C purpureum isolates Hawthorn and willow had greater lesion lengths after inoculation with the same isolate that had caused mortality in broom The results from this trial are being used to direct a larger field trial
