13. Investigação da microbiota endofítica onipresente em microplantas "axênicas / Investigation of ubiquitous endophytic microbiota in "axenic" microplants.
Tissue culture has been an important tool widely used for various purposes, among them the micropropagation has been highlighted due to the rapid production of healthy seedlings in a small space. Within this context, the term axenic plant has been distributed as an ideal to be achieved in this technique, which the search based on numerous methods that effect

14. 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

15. Diversidade da comunidade bacteriana endofítica de sementes de soja e o seu potencial biotecnológico / Endophytic bacterial community diversity of soybean seeds and its biotechnological potential
Plant tissues, including seeds, are inhabited by microorganisms called endophytes, whose interaction with the plant can offer advantages to the host. It is known that plants growth promotion is induced by indole acetic acid (IAA) synthesis, phosphate solubilization and nitrogen fixation, among others. The control of phytopathogenic fungi is also related to a

16. Diversity and genetic characterization of endophytic microbial communities associated with sugarcane / Diversidade e caracterização genética de comunidades microbianas endofíticas associadas à cana-de-açúcar
In Brazil, the sugarcane is one of the most important cultivated crops. The sugarcane has received increased interest in the last years because of increase of the cultivated area and ethanol production to be used as biofuel. Considering its economical importance and the possibility of the use of the genetically modified plants; this crop has become the aim o

17. Interaction between Methylobacterium extorquens and sugarcane (Saccharum sp.) / Interação entre Methylobacterium extorquens e cana-de-açúcar (Saccharum sp.)
Plants produce a variety of defense enzymes when colonized that can impair the microorganismsestablishment. This adverse condition in the host plant lead to a response from the microorganism, which is associated with the synthesis of a set of proteins and other molecules that affect the interaction with the host and shift the bacterial community associated.

18. 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.

19. Comunidade de fungos endofíticos associada à cana-de-açúcar convencional e geneticamente modificada / Community of endophytic fungi associated with conventional and genetically modified sugarcane
A diversidade da comunidade endofítica de fungos associada à cana-de-açúcar transgênica tolerante a imazapyr e suas linhas de cultivo não transgênicas foi avaliada por isolamento e ARDRA (Amplified rDNA Restriction Analysis). Cultivares transgênicos e não-transgênicos, e seu manejo (aplicação do herbicida ou remoção manual de daninhas), foram c

20. A comunidade bacteriana endofítica e epifítica de soja (Glycine max) e estudo da interação endófitos-planta. / Endophytic and epiphytic bacterial community from soybean (Glycine max) and study of the interaction endophytes-plant.
Bactérias endofíticas e epifíticas podem conferir ao seu hospedeiro características como maior resistência a condições de estresse, alterações nas condições fisiológicas, fixação de nitrogênio atmosférico, suprimento de nutrientes, produção de reguladores de crescimento vegetal, entre outros. Desta forma, o presente trabalho teve por objeti

21. Impact of Agricultural Practices on the Zea mays L. Endophytic Community
Agricultural practices are known to alter bulk soil microbial communities, but little is known about the effect of such practices on the plant endophytic community. We assessed the influence of long-term applications (20 years) of herbicides and different fertilizer types on the endophytic community of maize plants grown in different field experiments. Neste

22. A community of unknown, endophytic fungi in western white pine
The endophytic fungi of woody plants may be diverse as often claimed, and likewise, they may be functionally novel as demonstrated in a few studies. However, the endophyte taxa that are most frequently reported tend to belong to fungal groups composed of morphologically similar endophytes and parasites. Thus, it is plausible that endophytes are known (i.e.,

23. 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

24. Bacterial Communities Associated with Flowering Plants of the Ni Hyperaccumulator Thlaspi goesingense
Thlaspi goesingense is able to hyperaccumulate extremely high concentrations of Ni when grown in ultramafic soils. Recently it has been shown that rhizosphere bacteria may increase the heavy metal concentrations in hyperaccumulator plants significantly, whereas the role of endophytes has not been investigated yet. In this study the rhizosphere and shoot-asso
