objective: the genus trichoderma comprises a great number of fungal strains that act as biological control agents, the antagonistic properties of which are based on the activation of multiple mechanisms. methods: trichoderma strains exert biocontrol against fungal phytopathogens either indirectly, by competing for nutrients and space, modifying the environmental conditions, or promoting plant g...
White-nose syndrome has recently emerged as one of the most devastating wildlife diseases recorded, causing widespread mortality in numerous bat species throughout eastern North America. Here, we present an improved reference genome of the fungal pathogen Pseudogymnoascus destructans for use in comparative genomic studies.
Ten new cembrane-based diterpenes, locrassumins A-G (1-7), (-)-laevigatol B (8), (-)-isosarcophine (9), and (-)-7R,8S-dihydroxydeepoxysarcophytoxide (10), were isolated from a South China Sea collection of the soft coral Lobophytum crassum, together with eight known analogues (11-18). The structures of the new compounds were determined by extensive spectroscopic analysis and by comparison with ...
BACKGROUND Whole cell patch clamp recording and intracellular Ca2+ imaging were carried out on rat cultured dorsal root ganglion (DRG) neurones to characterize the actions of crude extracts and purified samples from Red Sea soft corals. The aim of the project was to identify compounds that would alter the excitability of DRG neurones. RESULTS Crude extracts of Sarcophyton glaucum and Lobophyt...
Many species of phytoplankton are susceptible to parasitism by fungi from the phylum Chytridiomycota (i.e. chytrids). However, few studies have reported the effects of fungal parasites on filamentous cyanobacterial blooms. To investigate the missing components of bloom ecosystems, we examined an entire field bloom of the cyanobacterium Anabaena macrospora for evidence of chytrid infection in a ...
When this study commenced in early 2004, only five Phaeophleospora species. had been reported from eucalypts of which only two; P. destructans (STE-U 1336) and P. epicoccoides (STE-U 1346) had been sequenced. In a former study, Phaeophleospora species emerged in two separate clades suggesting that Phaeophelospora is polyphyletic. The appearance and severity of lesions on eucalypt leaves are gen...
به منظور مطالعه پوسیدگی طوقه و ریشه برنج در سال 1388- 1387 از شالیزارهای استان های فارس و ایلام نمونه برداری به عمل آمد. با استفاده از کلید شناسایی بوث گونه hederea cylindrocarpon به عنوان عامل بیماری شناسایی گردید. آزمون بیماریزایی روی رقم عنبربو انجام گردید. این اولین گزارش از وقوع بیماری پوسیدگی ریشه و طوقه برنج در دنیا توسط گونه c. hederae می باشد.
