The fixation and transformation of atmospheric dinitrogen into ammonia and hence into organic e compounds is a crucial part of the nitrogen cycle. Nitrogenase, the enzyme responsible, has a wide taxonomie distribution in the bacteria and archaea, but is confined to a limited number of species. Among these, rhizobia, whieh form nodules on the roots of legumes, are recognised as the main contributors of biologieally-fixed nitrogen. Until recently, it has been generally accepted that legumes are nodulated exelusively by members of the alfa-proteobaeteria belonging to a number of related genera in the family Rhizobiaceae. In this document we review some results from recent studies that presents the newly-discovered beta-rhizobia which challenge the accepted...

Di-nitrogen fixation at the early and late growth stages of soybean
Provedor de dados: 1
Autores: Hamawaki, Raphael Lemes; Kantartzi, Stella K.
 Soybean derives a significant portion of the required nitrogen (N) from the symbiosis with rhizobia bacteria. However, information on the available genetic variation for N2 fixation capacity in different growth stages of soybean is limited. The objective of this study was to investigate the N2 fixation capacity of 22 soybean lines compared with that of non-nodulating and supernodulating checks at the early and late growth stages and identify the most informative traits for selection. Two cycles of greenhouse experiments were carried out to estimate the percentage of N derived from the atmosphere (%Ndfa) as well as 10 different traits related to N2 fixation. The results showed that %Ndfa was significantly different among the lines at the early and late...

ABSTRACT The benefits of mycorrhization occur with the growth of hyphae in colonized roots by promoting an increase of the contact surface which improves the initial growth due to a better absorption of water and nutrients. The objective was to evaluate the effect of arbuscular mycorrhizal fungus Rhizophagus clarus inoculation over the initial development and nutritional response of six genotypes of Coffea arabica L. Six genotypes of Coffea arabica L. were used (MGS Aranas, H29-1-8-5, Red Catuai IAC 144, IPR 100, Catigua MG2, Paraíso H 419-1) and with arbuscular mycorrhizal fungus - AMF: Rhizophagus clarus and without the application of the fungus. For the production of coffee seedlings, seeds were placed to germinate in plastic trays with sterile sand....
