| Desde 1980, a pesquisa tem mostrado a inutilidade da pratica da adubacao nitrogenada na semeadura da soja. Entretanto, com a expansao do plantio direto, na regiao do Cerrado, novamente surgiram dúvidas, por parte de alguns agricultores, sobre a eficiencia do processo de inoculacao e sobre a necessidade, ou nao, da utilizacao de doses de "arranque" de adubo nitrogenado na semeadura, para superar possiveis problemas relacionados a imobilizacao do N e a competicao inicial com plantas invasoras. Foram conduzidos, na Embrapa Cerrados, dois experimentos em areas sob plantio direto (PD) e dois em areas sob plantio convencional (PC) para avaliar a resposta da soja a pequenas doses de N na semeadura. Os tratamentos consistiram de quatro niveis de N (0, 20, 30, e 40... |

| ABSTRACT: Soybean [Glycine max (L.) Merr.] is the most important legume cropped worldwide, with an economic value attributed mainly to the high protein content of the grain, which, in turn, demands a heavy supply of nitrogen. An environmentally friendly source of nitrogen at low cost to farmers is represented by the biological fixation of atmospheric nitrogen that takes place is association with symbiotic bacteria. For the soybean, the association occurs mainly with bacteria belonging to the species Bradyrhizobium japonicum and Bradyrhizobium elkanii, but our knowledge about gene expression associated with the symbiosis is still poor. This work - part of an effort by the Soybean Genome Consortium (Genosoja)?was conducted with the aim of achieving better... |

| The symbiotic relationship between legumes and nitrogen fixing bacteria is critical for agriculture, as it may have profound impacts on lowering costs for farmers, on land sustainability, on soil quality, and on mitigation of greenhouse gas emissions. However, despite the importance of the symbioses to the global nitrogen cycling balance, very few rhizobial genomes have been sequenced so far, although there are some ongoing efforts in sequencing elite strains. In this study, the genomes of fourteen selected strains of the order Rhizobiales, all previously fully sequenced and annotated, were compared to assess differences between the strains and to investigate the feasibility of defining a core ?symbiome??the essential genes required by all rhizobia for... |
