چکیده
The bark beetle Scolytogenes birosimensis Niijima is suspected to be involved in the decline of Pittosporum tobira (Thunb. ex Murray) Aiton in the coastal areas of Japan. We isolated fungi from adult S. birosimensis in nine different localities in Japan to assess their potential association and predict their contribution to the success of the beetle. Results from morphological identification of associated fungi showed that the beetle was associated with Fusarium solani and Candida spp. Furthermore, molecular analysis showed that F. solani was most closely related to the plant pathogenic fungus F. solani f. sp. mori. Fungal isolation from surface-sterilized, dissected beetles and scanning electron miscroscope (SEM) observation of the body surface suggested that the associated fungi were carried in the pits on the beetles' elytra. These findings contribute to the understanding of the relationships between S. birosimensis and its associated fungi.

Antimicrobial activities against periodontopathic bacteria of Pittosporum tobira and its active compound.
The study of medicinal plants for treatment of periodontitis is of great value to establish their efficacy as sources of new antimicrobial drugs. Five hundred and fifty eight Korean local plant extracts were screened for antibacterial activity against representative periodontopathic bacteria such as Porphyromonas gingivalis, Prevotella intermedia, and Fusobacterium nucleatum. Among the various ...

The volatile components of the flower and fruit oils from Pittosporum tobira (Thunb.) Ait. grown in Iran, obtained through hydrodistillation, were analyzed by GC/MS. Sixteen compounds (representing 90.7% of the oil) and seventeen constituents (representing 89.9% of the oil) were identified in the flower and fruit oils, respectively. While the flower oil contained a-pinene (38.6%), n-nonane (11....
متن کاملFlammability of some ornamental species in wildland-urban interfaces in southeastern France: laboratory assessment at particle level.
Assessment of the flammability of ornamental vegetation (particularly hedges) planted around houses is necessary in light of the increasing urbanization of the wildland-urban interfaces (WUIs) and the high fire occurrence in such areas. The structure and flammability of seven of the species most frequently planted as hedges in Provence (southeastern France) were studied at particle level. Spati...

Background: Pittosporum tobira (Thunb.) Aiton is an aromatic medicinal plant widely cultivated in the world. However, the essential oils (EOs) from P. tobira flowers for anti-cancer potential is still not systematically studied. The present aim to elucidate the phytochemical composition of the EOs and to explore mechanism of anticancer action. Methods: The EOs were extracted and analyzed by hea...
