1. EVALUATION OF THE METABOLIC PRODUCTION OF THE ENDOPHYTIC FUNGUS Phomopsis sp.
Endophytic microorganisms have been shown to be an important source of bioactive compounds, and much has been studied about their metabolites. For example, compounds with different biological activities have been isolated from Phomopsis sp. The metabolic study of this genus may lead to a better understanding of the routes of production of metabolites of inte

2. Dark septate endophyte decreases stress on rice plants
Abstract Abiotic stress is one of the major limiting factors for plant development and productivity, which makes it important to identify microorganisms capable of increasing plant tolerance to stress. Dark septate endophytes can be symbionts of plants. In the present study, we evaluated the ability of dark septate endophytes isolates to reduce the effects o

3. Antibacterial, antifungal and cytotoxic activities exhibited by endophytic fungi from the Brazilian marine red alga Bostrychia tenella (Ceramiales)
Abstract Marine environment is one of the most important sources regarding natural products research. Besides, marine microorganisms have been denominated as a talented natural source for discovery of new leads. Although the association of macroalgae and fungi has been described regarding ecological issues, there is a lack of studies about marine seaweed end

4. Endophytes: exploitation as a tool in plant protection
Endophytes are symptomless fungal or bacterial microorganisms found in almost all living plant species reported so far. They are the plant-associated microbes that form symbiotic association with their host plants by colonizing the internal tissues, which has made them valuable for agriculture as a tool in improving crop performance. Many fungal endophytes p

5. Ecologia de Methylobacterium spp. na planta hospedeira / Methylobacterium spp. ecology in the host plant
The genus Methylobacterium, constituted by PPFMs - pink-pigmented facultative methylotrophic, are able to fix nitrogen, nodule the host plant, produce cytokines and enzymes involved in induction of systemic resistance such as pectinase and cellulase, inducing plant growth. Methylobacterium sp. has been described as endophyte or epiphyte in different host pla

6. Comunidade bacteriana endofítica em microplantas de abacaxizeiro: estrutura, diversidade e sua influência na morfofisiologia após antibioticoterapia / Bacterial endophyte community in pineapple microplants: structure, diversity and its influence on morphophysiology after antibiotic therapy
O cultivo in vitro de plantas possibilita o controle de fatores ambientais e nutricionais, facilitando o estudo da interação planta-bactéria e a interpretação de eventuais alterações morfofisiológicas nas microplantas, decorrentes dessa interação. Entretanto, a presença de bactérias endofíticas na micropropagação é quase sempre caracterizada

7. Genetic transformation and pathogenicity of Guignardia citricarpa / Transformação genética e patogenicidade de Guignardia citricarpa
O Brasil é líder absoluto no comércio internacional de suco de laranja concentrado congelado participando com 82% do volume comercializado no mundo. Guignardia citricarpa é um fungo Ascomiceto agente causal da Mancha Preta dos Citros (MPC), uma doença importante no contexto da Citricultura, causando lesões negras em frutos tornando-os impróprios para

8. Potencial biotecnológico de fungos de gênero Penicillium e interação com cana-de-açúcar / Biotechnological potential of fungi Penicillium and interaction with sugarcane
Os fungos endofíticos têm sido reconhecidos pela sua grande importância para as plantas hospedeiras, pois podem conferir proteção contra insetos herbívoros e patógenos, promover o crescimento vegetal, além de produzir metabólitos secundários com atividades biológicas diversas, entre outros. A cana-de-açúcar é uma cultura de grande importância

9. Isolamento de metabÃlitos antifÃngicos de Streptomyces sp. UFPEDA 3347, endÃfito de Momordica charantia L.(Cucurbitaceae)
Endophytic microorganisms now come as an important source for the production of secondary metabolites with antimicrobial, antifungal, antitumoral, antimalaria action, among others. For production of bioactive metabolites from Streptomyces sp. UFPEDA 3347, endophyte from Momordica charantia L., different medium of fermentation were tested and the antifungal a

10. Diversidade e potencial biotecnológico de fungos endofíticos de cacau (Theobroma cacao L.) / Diversity and biotechnological potential of the cacao (Theobroma cacao L.) endophytic fungi
Endophytes are all microorganisms, culturable or not, that inhabit the interior of plant tissues, causing no harm to the host, and that do not develop external structures, excluding in this way, nodulating bacteria and mycorrhizal fungi. Theobroma cacao L. is important to food and cosmetic industry due the fact that it is used for production of cacao butter.

11. Response of Endophytic Bacterial Communities in Potato Plants to Infection with Erwinia carotovora subsp. atroseptica
The term endophyte refers to interior colonization of plants by microorganisms that do not have pathogenic effects on their hosts, and various endophytes have been found to play important roles in plant vitality. In this study, cultivation-independent terminal restriction fragment length polymorphism analysis of 16S ribosomal DNA directly amplified from plan
