1. Characterization of Bacillus isolates of potato rhizosphere from andean soils of Peru and their potential PGPR characteristics
Bacillus spp. are well known rhizosphere residents of many crops and usually show plant growth promoting (PGP) activities that include biocontrol capacity against some phytopatogenic fungi. Potato crops in the Andean Highlands of Peru face many nutritional and phytophatogenic problems that have a significant impact on production. In this context is important

2. Analysis of secondary metabolites produced by endophytic fungi associated to Cupressus lusitanica / Análise de metabólitos secundários produzidos por fungos endofíticos associados à Cupressus lusitanica
Some phytopatogenic fungi found in Cupressus species produces phytotoxins very aggressive to the host plant. Surprisingly, these toxins are diterpenoids structures, as well as some endogenus metabolites in Cupressus species. This fungi ability appears to be a specialized strategy in the association fungi-plant. These observations motivated the development of

3. Epidemiologia comparativa de podridão do pessegueiro causada por Monilinia fructicola e Monilinia laxa: o monociclo / Comparative epidemiology of peach brown rot caused by Monilinia fructicola and Monilinia laxa: the monocycle
Frente à recente detecção em território brasileiro de Monilina laxa, que assim como M. fructicola, é causadora da podridão parda do pessegueiro, e à falta de informações sobre a epidemiologia dos patógenos causadores da doença em regiões subtropicais, surgiu a necessidade deste trabalho, que teve por objetivos determinar as melhores condições d

4. Micobiota fitopatogênica associada à planta invasora Tibouchina herbacea / Mycobiota of the invasive weed Tibouchina herbacea
Weed plant invasions, in natural as well as in anthropic modified environments, results in significant economical losses or ecosystem disequilibrium. Some ecosystems are more susceptible than others to biological invasions, once they have disharmonic fauna and flora (with empty ecological niches or niches occupied by low adapted species to the ecological fun

5. Técnicas modernas em espectrometria de massas aplicadas no isolamento de bioherbicidas produzidos por microrganismos / Modern Techniques on Mass Spectrometry applied to the isolation of bioherbicides produced by microorganisms
In this work a quick and efficient methodology was employed for the identification of phytotoxic metabolites produced by microorganisms. The isolation of the bioactive compound was guided by Lemna minor bioassay. Mass spectrometry, especially LC-MS, was used to accelerate the process of identification of the phytotoxin. All bacteria were symbiotic to the phy

6. Aspectos químicos envolvidos nas interações de Citrus com fitopatógenos / CHEMICAL ASPECTS RELATED TO THE INTERACTION BETWEEN Citrus PLANTS AND PHYTOPATOGENIC FUNGI
This present thesis describes the development of analytical methodologies involving the HPLC-PDA-MS/MS coupling to verify the production of both polar and non-polar metabolites in orange trees produced by grafting Citrus sinensis onto Citrus limonea. By the use of such kind of method, it was possible to verify the production of both polymethoxy and glycosyl
