BACKGROUND The aim of this study was to evaluate the antimicrobial activity and the cytotoxicity of the ethanol crude extract, fractions and isolated compounds from the twigs of Eriosema robustum, a plant used for the treatment of coughs and skin diseases. METHODS Column chromatographic and spectroscopic techniques were used to isolate and identify eight compounds, robusflavones A (1) and B (...

Sugarcane (Saccharum spp. hybrids) is one of the most important commercial crops for sugar, ethanol, and other byproducts production; therefore, it great significance to carry out genetic research. Assessing population structure diversity plays a vital role in managing resources gene mapping. In this study, we assessed among 196 Saccharum accessions, including 34 S. officinarum, 69 spontaneum, ...

The identity and taxonomy of the genus Crassolabium are discussed based on examination of material of C. australe, its type species and its comparison with Iberian species of close genera. The existence of refractive masses (thickenings) at the inner core of lateral lips, the most distinctive diagnostic feature of Crassolabium, is considered to be of minor taxonomical significance because of it...

The 45S ribosomal DNA (rDNA) units are separated by an intergenic spacer (IGS) containing the signals for transcription and processing of rRNAs. For the first time, we sequenced and analyzed the entire IGS region from three original species within the genus Saccharum, including S. spontaneum, S. robustum, and S. officinarum in this study. We have compared the IGS organization within three origi...

during the past decade, natural plant products as environmentally safe option have received attention for controlling phytopathogenic diseases. investigation of plants containing natural antimicrobial metabolites for plant protection has been recognized as a desirable method of disease control. the fungus fusarium oxysporum causes diseases such as root rot, damping off and fusarium wilt and it ...
