Pine mushroom (Tricholoma matsutake) is one of the most valued ectomycorrhizal fungi in Asia because of its unique pine-like aroma; however, due to exceptionally slow growth of its mycelia in artificial conditions, its cultivation has been largely deemed as not possible. Previous studies have shown that some bacteria and a few Trichoderma species associated with pine mushroom promoted the growth of T. matsutake isolate, but this effect is relatively unexplored. In this study, we investigated the diversity of microfungi in the fairy ring of T. matsutake and their effect on the growth of T. matsutake isolate. From 184 fungal isolates, 28 species were identified based on suitable molecular markers. Penicillium was most frequently observed (16 species), followed by Trichoderma (4 species). Five Zygomycota species showed a high promoting effect on the growth of T. matsutake while the effects of ascomycetes were mixed. The microfungi that promote the growth of T. matsutake can be useful for forest nursery and artificial cultivation of T. matsutake.

Tricholoma Bakamatsutake

During mycelial culture of Tricholoma robustum, the medium gradually became acidified to approximately pH 3.9. High performance liquid chromatography showed that gluconic acid was secreted into the culture medium, and the amount of gluconic acid produced was measured by enzymatic analysis. Gluconic acid synthesis by all other related species, Tricholoma matsutake, Tricholoma caligatum, Tricholoma ponderosum, Tricholoma fulvocastaneum, and Tricholoma zelleri was poor, except for Tricholoma bakamatsutake, which showed relatively high productivity. Activity of glucose oxidase, which is responsible for gluconic acid production, was highest in T. robustum and second highest in T. bakamatsutake. The activity in these two species was much higher than those of other species. These results indicate that gluconic acid was synthesized from glucose by glucose oxidase in T. robustum as well as in T. bakamatsutake. Key words: ectomycorrhizal fungi, gluconic acid, glucose oxidase, Tricholoma robustum.

The northern of Khuzestan province in Iran is mainly considered as one of the major areas of miniature rose production. Blossom blight caused by Botrytis cinerea has recently become a serious limiting factor in rose production in pre and post-harvest. In current study, an attempt was made to evaluate the inhibitory potential of some local Trichoderma spp. strains against B. cinerea under in vitro and in vivo conditions. The in vitro results showed that all Trichoderma spp. strains were significantly able to reduce the mycelial growth of the pathogen in dual culture, volatile and non-volatile compounds tests compared with control, with superiority of T. atroviride Tsafi than others. Under in vivo condition, the selected strain of T. atroviride Tsafi had much better performance than T. harzianum IRAN 523C in reduction of disease severity compared with the untreated control. Overall, the findings of this study showed that the application of Trichoderma-based biocontrol agents such as T. atroviride Tsafi can be effective to protect cut rose flowers against blossom blight.
