Because of its resistance to antibiotics, Staphylococcus aureus causes many of problems in hospital and society. As one of the main reasons of clinical infections it can cause to serious surgical and cutaneous infections and pneumonia. The inhibitory effect of the essential oils include; Eucalyptus largiflorence, E. camaldulensis, E. malliodora and E. polycarpa as a natural and herbal antimicro...

Eucalyptus species synthesize a wealth of polyketide natural products, but no relevant biosynthetic enzyme has been identified. Degenerate primers designed from conserved regions of fourteen chalcone synthase superfamily enzymes were used to isolate gene fragments from at least five different Type III polyketide synthases (PKSs) in E. camaldulensis and E. robusta.

Stressful episodic weather is likely to affect the C balance of trees as the climate changes, potentially altering survival. However, the role of elevated CO2 concentration ([CO2]) in tolerating off-season episodic extremes is not clear. We tested for interactive effects of elevated CO2 and springtime heat stress on photosynthesis for seven genotypes of Eucalyptus camaldulensis Dehnh. var. cama...

Eucalyptus is the most economically important hardwood plantation tree cultivated in tropical and subtropical countries. Inter-simple sequence repeat (ISSR) markers were used to evaluate genetic relationships within and between individuals of six Eucalyptus species. A total of 583 loci (265 to 1535 bp) were amplified from 149 individuals belonging to the six Eucalyptus species using seven ISSR ...

The cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Bruchidae), is an important pest of stored cowpea, Vigna ungiculata (L.) Walpers (Fabales: Fabaceae), with ample distribution in tropical and subtropical regions. Many plant essential oils have a broad-spectrum activity against pest insects, and these oils traditionally have been used in the protection of stored products. In this study...

The potential of 6 tree species (Leucaena leucocephala, Acacia mangium, Peltophorum pterocarpum, Pterocarpus macrocarpus, Lagerstroemia floribunda, Eucalyptus camaldulensis) for phytoremediation of Pb in sand tailings (total Pb >9850 mg kg(-1)) from KEMCO Pb mine in Kanchanaburi province, Thailand, were investigated employing a pot experiment (3 months) and field trial experiment (12 months). I...

The present work aimed at regenerating plants of Eucalyptus camaldulensis from the cotyledonary explants and describing the anatomy of the tissues during callogenesis and organogenesis processes, in order to determine the origin of the buds. The cotyledonary leaves of E. camaldulensis were cultured in Murashige and Skoog (MS), WPM and JADS media supplemented with 2.7 μM NAA and 4.44 μM BAP. The...

the aim of this study was to investigate the allelopathic effects of eucalyptus camaldulensis on germination and early seedling growth of festuca arundinacea under laboratory condition in order to determine the effect of pretreatments on decreasing the destructive effects of allelopathic compounds. the chemical stimulators used in this study included 3 levels of gibberellic acid, 3 levels of sa...
