13. Efeito de fontes e doses de molibdenio na sobrevivencia do Bradyrhizobium e na fixacao biologica de nitrogenio em soja.
O molibdênio (Mo) é essencial para a soja, por participar da enzima nitrogenase, sintetizada pelas bactérias durante o processo de fixação biológica do nitrogênio (FBN) por simbiose. A aplicação do Mo nas sementes no momento da semeadura antecede a aplicação do inoculante. O contato do Mo com o inoculante prejudica o Bradyrhizobium e, conseqüente

14. Nodulation and N2 fixation effectiveness of Bradyrhizobium strains in symbiosis with Adzuki Bean, Vigna angularis
In pot experiment, one isolate Knj from a Serbian soil, four strains of Bradyrhizobium japonicum and three strains of Bradyrhizobium spp. were examined for the effect on adzuki bean nodulation and effectiveness in symbiotic N2 fixation. All the tested strains produced root nodules in adzuki bean. Strains of B. japonicum showed high potential of N2 fixation,

15. Efeito do recobrimento de sementes com fósforo na qualidade das sementes, nodulação e crescimento das plantas de soja / Effect of coated of seed with phosphorous on quality of seeds, nodulation and growth of plants of soy
The seed is one of the principal input of agriculture, because carry all genetic potential of plant, determining, largely, the success of the crop. The objective this work was study the effect of phosphorous, by coated of seeds of soy with phosphorous, have with sources monobasic phosphorous phosphate, on germination and vigor of two lots os soy seeds, with

16. Caracterização fenotípica e produção de biopolímeros por bactérias isoladas de nódulos de guandu [(Cajanus cajan (L.) Millsp.]. 2009, 166f. / Phenotypic characterization and biopolymers production by bacteria isolated from pigeonpea [Cajanus cajan (L.) Millsp.] root nodules. Seropédica: UFRRJ, 2008. 166p.
The biological nitrogen fixation (BNF) is a natural process carried out by prokaryotes collectively called diazotrophs. Among the diverse microorganisms able to fix the atmospheric nitrogen, stand out those capable of set up mutualistic associations with legume plants in specialized structures called nodules. Thus the search for microorganisms able to establ

17. Efeito de Alumínio, Molibdênio e de Estirpes de Rizóbio em Arachis pintoi / Effect of Aluminum, Molybdenum and strains of Rizóbio in Arachis pintoi
In a modern cattle-breeding using pastures that allows a gain of weight is an essential factor. The Arachis pintoi is an option to a good alimentary diet and to the recuperation of degraded pastures, due to its potential in biological fixation of nitrogen and resistance to acid soil with high contents of aluminium. Experiments were conducted in greenhouse an

18. Translocation of Co and Mo applied in different times in soybeans / Translocação de Co e Mo aplicados em diferentes épocas na cultura da soja
This study evaluated the translocation of Co and Mo applied in different times on the development of soybeans, determining their presence in soybean root nodules, leaves and grains. The assay was done in Fazenda Canadá, located in Uberlândia, MG. The experimental design was randomized blocks with seven treatments and six repetitions. Each experimental unit

20. Transporte de nitrogenio e metabolismo da aspargina em soja (Glycine Max L.) sob deficiencia na assimilação do nitrogenio
Experiments with soybean plants and other legumes were conducted under greenhouse conditions. Both nodulated and non-nodulated plants were found to present substantially increased aspartic acid levels and lower asparagine in the xylem bleeding sap under conditions that limit nitrogen assimilation. In soybean, the response was reversed when optimum conditions

21. Respostas a diferentes doses de calcario, de fosforo e de aplicação de molibdenio via foliar em quatro leguminosas forrageiras arboreas e arbustivas de clima tropical Leucaena leucocephala (Lam) witt., Leucaena pallida, Sesbania sesban (L.) Merr., e Codariocalyx gyroides (L. F. de Hassk)
Two experiments were carried out with four different fodder tree legumes Leucaena leucocephala, Leucaena pallida, Sesbania sesban and Codariocalyx gyroicks. The main objective of the first experiment was to determinate the energy tragment distribution trom the seed, to produce shoot and root system using seed laboratory facilities. The second experiment was

22. Transient Susceptibility of Root Cells in Four Common Legumes to Nodulation by Rhizobia 1
Root cells of four common legumes were found to remain susceptible to nodulation by rhizobia for only a short period of time. Delayed inoculation experiments conducted with these legume hosts indicated that the initially susceptible region of the root became progressively less susceptible if inoculations were delayed by a few hours. Profiles of the frequency

23. Effect of lectin on nodulation by wild-type Bradyrhizobium japonicum and a nodulation-defective mutant.
The nodulation characteristics of wild-type Bradyrhizobium japonicum USDA 110 and mutant strain HS111 were examined. Mutant strain HS111 exhibits a delayed-nodulation phenotype, a result of its inability to initiate successful nodulation promptly following inoculation of the soybean root. Previously, we showed that the defect in initiation of infection leadi

24. Invasion of Lotus japonicus root hairless 1 by Mesorhizobium loti Involves the Nodulation Factor-Dependent Induction of Root Hairs1[w]
In many legumes, including Lotus japonicus and Medicago truncatula, susceptible root hairs are the primary sites for the initial signal perception and physical contact between the host plant and the compatible nitrogen-fixing bacteria that leads to the initiation of root invasion and nodule organogenesis. However, diverse mechanisms of nodulation have been d
