The study reported here is a classical bottom-up proteomic approach where proteins from wasp venom were extracted and separated by 2-DE; the individual protein spots were proteolytically digested and subsequently identified by using tandem mass spectrometry and database query with the protein search engine MASCOT. Eighty-four venom proteins belonging to 12(More)
The genus Xanthomonas is composed of several species that cause severe crop losses around the world. In Latin America, one of the most relevant species is Xanthomonas campestris pv. campestris, which is responsible for black rot in cruciferous plants. This pathogen causes yield losses in several cultures, including cabbage, cauliflower and broccoli.(More)
Gluconacetobacter diazotrophicus is a micro-aerobic bacterium able to fix atmospheric nitrogen in endophytic mode. A proteomic approach was used to analyze proteins differentially expressed in the presence and absence of sugarcane plantlets. Two-dimensional gel electrophoresis (2-DE) showed 42 spots with altered levels of expression. Analysis of these spots(More)
Wheat (Triticum aestivum L.) may be exposed to different stress conditions that influence its productivity. In southern Brazil the rainfed wheat crop is limited by dry spells consisting of short periods of drought during rainy periods. One way to confer tolerance to the drought ́s effects and stimulate plant productivity is the action of a group of bacteria(More)
