13. Diversidade de fungos micorrÃzicos arbusculares em solo de agroecossistemas do semiÃrido cearense / Diversity of arbuscular mycorrhizal fungi in the soil of agroecosystems in semi-arid CearÃ
Os Fungos MicorrÃzicos Arbusculares - FMA sÃo microrganismos chave tanto em agroecossistemas como em ecossistemas naturais. SÃo responsÃveis por uma simbiose que ocorre com a maioria das plantas vasculares. Atuam em mutualismo com as plantas, auxiliando-as na absorÃÃo de nutrientes pouco mÃveis no solo, alÃm de aumentar a absorÃÃo de Ãgua e proteg

14. Nutrientes e fungos micorrízicos arbusculares como fatores limitantes ao crescimento de Toona ciliata M. Roem. var. australis. 2010. / Nutrients and arbuscular mycorrhizal fungi as factors limiting the growth of Toona ciliata M. Roem. var. australis. 2010.
O presente trabalho teve como objetivo avaliar alguns fatores limitantes ao crescimento de Toona ciliata M. Roem. var. australis (cedro-australiano). No capítulo I, avaliou-se o crescimento de mudas de cedro-australiano inoculadas com fungos micorrízicos arbusculares (FMAs), Acaulospora laevis, A. morrowiae, Entrophospora colombiana, E. contigua, Gigaspora

15. Interação entre micorrizas arbusculares e ácido giberélico no desenvolvimento vegetativo de plantas de citrange carrizo / Effect of arbuscular mycorrhizae and gibberelic acid interaction on vegetative growth of carrizo citrange seedlings
As plantas cítricas são, geralmente, dependentes dos fungos micorrízicos arbusculares (FMA). Há relatos indicando a existência de um intercâmbio hormonal entre as plantas e os FMA e também a comprovação de que a simbiose planta-FMA é beneficiada pela aplicação radicular de auxinas. Com o objetivo de verificar se esta interação também ocorre co

16. Avaliação de fungos micorrízicos arbusculares e ectomicorrízicos para seleção de simbioses eficientes com leguminosas arbóreas do gênero Acacia. / Arbuscular mycorrhizal and ectomycorrhizal fungi evaluation for selection of efficient symbiosis for leguminous trees of Acacia genus.
The present research aimed the selection of FMA and isolate of fECTOs of high symbiotic efficiency for Acacia mangium, Acacia holosericea, and Acacia auriculiformis with the purpose of evaluating the best combination of inoculation among the different types of mycorrhizae. The experiments were carried on at Embrapa Agrobiologias greenhouse, in Seropédica/RJ

17. Identification and characterization of genes differentially expressed during arbuscular mycorrhiza development in sugarcane / Identificação e caracterização de genes com expressão diferencial durante o desenvolvimento de micorrizas arbusculares em cana-de-açúcar
Arbuscular mycorrhizae (AM) are mutualistic symbiotic associations between fungi of the order Glomales and most of the terrestrial plants. The molecular mechanisms regulating AM development and efficiency are not well understood so that agricultural large scale application is so difficult. Although so many approaches are being used to the identification of d

18. Formação de micorriza arbuscular e análise do transcritoma de raízes de cana-de-açúcar colonizadas por Glomus clarum na presença de herbicidas / Arbuscular mycorrhizal formation and transcriptome analyses of sugarcane roots colonized by Glomus clarum in the presence of herbicides
The arbuscular mycorrhizae (AM) are symbiotic root-fungus associations that play a key role in natural and agricultural ecosystems, through the enhancement of nutrients absorption in the soil and its transference into the plants. The AM may promote the growth of many plants, among them are the sugarcane. Even thought the herbicide utilized in the agriculture

19. Análises do proteoma de raízes de cana-de-açúcar e da expressão de uma peroxidase apoplástica responsiva à micorriza arbuscular / Analysis of the sugarcane roots proteome and expression of an arbuscular mycorrhizaresponsive apoplastic peroxidase
Arbuscular mycorrhizae (AM) are symbiotic associations between fungi of the phylum Glomeromycota and most of the plant species. Even though the molecular mechanisms controlling the colonization process and AM development are largely unknown, proteins with differential accumulation in AM may have important regulatory roles. The aim of this work was to detect,

20. Activity analiysis of some antioxidant enzymes in soybean plants (Glycine max L. Merr.) under levels of manganese, in function of arbuscular mycorrhizae. / Análise da atividade de algumas enzimas antioxidantes em plantas de soja (Glycine max L. Merr.) sob níveis de manganês, em função da micorriza arbuscular.
Brazilian soils are predominantly acid, which is considered a common incident in tropical regions. Soil acidity in combination with biotic and non-biotic factors can result manganese toxicity in plants, limiting their development. The use of conventional agricultural practices promotes an increase in Mn toxicity, as it reduces the soil content of organic mat

21. Airstream Fractionation of Vesicular-Arbuscular Mycorrhizal Fungi: Concentration and Enumeration of Propagules
Spores and fragments of vesicular-arbuscular mycorrhizal fungi in dry soils were concentrated up to 100-fold when the soils were partitioned by fluidization and elutriation with a series of upward airstreams at progressively increasing velocities. The propagules were transported with the finer soil particles according to their equivalent spherical diameters.

22. Osmotic Adjustment in Leaves of VA Mycorrhizal and Nonmycorrhizal Rose Plants in Response to Drought Stress 1
Osmotic adjustment in Rosa hybrida L. cv Samantha was characterized by the pressure-volume approach in drought-acclimated and unacclimated plants brought to the same level of drought strain, as assayed by stomatal closure. Plants were colonized by either of the vesicular-arbuscular mycorrhizal fungi Glomus deserticola Trappe, Bloss and Menge or G. intraradic
