The scorpion Tityus stigmurus is widely distributed in Northeastern Brazil and known to cause severe human envenoming, inducing pain, hyposthesia, edema, erythema, paresthesia, headaches and vomiting. The present study uses a transcriptomic approach to characterize the gene expression profile from the non-stimulated venom gland of Tityus stigmurus scorpion.(More)
Sugarcane is the source of sugar in all tropical and subtropical countries and is becoming increasingly important for bio-based fuels. However, its large (10 Gb), polyploid, complex genome has hindered genome based breeding efforts. Here we release the largest and most diverse set of sugarcane genome sequences to date, as part of an on-going initiative to(More)
Plukenetia volubilis Linneo, or Sacha inca, is an oleaginous plant from the Euphorbiaceae family. The aim of this work was to perform a chemical and biological analysis of different leaf extracts from P. volubilis such as aqueous extract (AEL), methanol (MEL), ethanol (EEL), chloroform (CEL), and hexane (HEL). Thin layer chromatography analysis revealed the(More)
Sulfated polysaccharides (SP) are found mainly in seaweeds and animals. To date, they have only been found in six plants and all inhabit saline environments. Furthermore, there are no reports of SP in freshwater or terrestrial plants. As such, this study investigated the presence of SP in freshwaters Eichhornia crassipes, Egeria densa, Egeria naja, Cabomba(More)
Chromobacterium violaceum is a Gram-negative beta-proteobacterium that inhabits a variety of ecosystems in tropical and subtropical regions, including the water and banks of the Negro River in the Brazilian Amazon. This bacterium has been the subject of extensive study over the last three decades, due to its biotechnological properties, including the(More)
Sugarcane is a tropical crop used for sugar and biofuel production in tropical and equatorial regions of the globe. Sugarcane flowering is intrinsically induced in equatorial regions due to long-day conditions. Flower development is problematic for this crop because it halts vegetative growth, leading to a reduction of the sugar accumulated in the stalks,(More)
