Using GC-MS the volatile composition of Jasonia glutinosa D. C., was studied by comparing two different methods for the isolation of a volatile fraction: distillation from the fresh plant in order to obtain the essential oil, and direct thermal desorption (DTD). Compared with essential oil extraction the main advantages of the DTD technique are the smaller sample amount required, and the increa...

In search of plant genes expressed during early interactions between Casuarina glauca and Frankia, we have isolated and characterized a C. glauca gene that has strong homology to subtilisin-like protease gene families of several plants including the actinorhizal nodulin gene ag12 of another actinorhizal plant, Alnus glutinosa. Based on the expression pattern of cg12 in the course of nodule deve...

Recent developments in sequencing technologies and bioinformatics analyses provide an unprecedented opportunity for cost and time effective high quality microsatellite marker discovery in nonmodel organisms for which no genomic information is available. Here, we use shotgun pyrosequencing of a microsatellite-enriched library to develop, for the first time, microsatellite markers for Alnus gluti...

Sooty mold fungi are often associated with honeydew which insects secrete while feeding on the plant. A great variety of these fungi occur in the North of Iran, especially on Citrus ssp which is one of the most widely cultivated fruit trees in this region. During last 10 years, several collections of these fungi examined and 15 species have been recorded. In this paper seven previously unreport...

Two new sesquiterpene alcohols have been isolated from the aerial parts of Jasonia glutinosa D. C. The structure of these sesquiterpenes were characterized by 1D and 2D NMR techniques (DQCOSY. TOCSY, NOESY, HMQC and HMBC) as (11R)-eudesm-4-en-11,12-diol and (11R)-eudesmane-5alpha, 11,12-triol.

Non-native nitrogen-fixing Acacia species have been invading riparian ecosystems worldwide, potentially threatening stream communities that strongly depend on allochthonous litter. We examined the effects of invasion native deciduous temperate forests by litter decomposition and associated fungal decomposers in streams. Litter (Alnus glutinosa Quercus robur) invasive (Acacia melanoxylon) were e...
