The aim of this study was to verify the possible interactions between ethanol extracts of Amburana cearensis A. C. Smith and Anadenanthera macrocarpa (Benth.) Brenan, combined with six antimicrobial drugs against multiresistant strains of Staphylococcus aureus and Escherichia coli isolated from humans. The antibacterial activity of the extracts was determined using the minimum inhibitory concen...

For a better understanding of the functionality and pathogenicity of beet soil-borne virus (BSBV), full-length cDNA clones have been constructed for the three genomic RNAs. With the aim of assessing their effectiveness and relative contribution to the virus housekeeping functions, transcripts were inoculated on Chenopodium quinoa and Beta macrocarpa leaves using five genome combinations. Both R...

Taxonomic study of the crustose lichen Porpidia was performed in this paper. Three species are described, including two recorded species and one new record: Porpidia macrocarpa (DC.) Hertel & A. J. Schwab. A description of each species is presented along with morphological, anatomic, and chemical characteristics. A key to the identification of species of Porpidia is also presented.

BACKGROUND Rhizomania is one of the most devastating diseases of sugar beet. It is caused by Beet necrotic yellow vein virus (BNYVV) transmitted by the obligate root-infecting parasite Polymyxa betae. Beta macrocarpa, a wild beet species widely used as a systemic host in the laboratory, can be rub-inoculated with BNYVV to avoid variation associated with the presence of the vector P. betae. To b...

water-distilled essential oil of ferulago macrocarpa (umbelliferae) fruits was analyzed using gc-ms for the first time. forty-two components comprising 99.5% of the total oil were identified, of which bornyl acetate (40.8%), 2,3,6-trimethyl benzaldehyde (7.2%), δ-selinene (5.5%), 1,10-di-epi-cubenol (5.1%), germacrene d (3.5%), β-phellandrene (3.5%) and α-pinene (3.4%) were found to be the majo...

Morphological, anatomical, quantitative microscopy powder microscopy, physical constant preliminary phytochemical analysis and fluorescence analysis of the leaves of Aglaia roxburghiana Var. Beddome were carried out.

[1] Infragravity waves can be observed at the 1000 m deep ocean bottom broadband seismic station MOBB on stormy as well as quiet days. When compared to the energy of the short-period ocean waves recorded at the local buoys, infragravity waves in the longer than 20 s period band are found to be mainly locally generated from shorter-period waves. Two types of modulation of the infragravity signal...
