Resumo: Grain, forage and tree legumes were surveyed for ureide content, type of nodules and nitrogenase activity. Thirty-six legume species were studied representing seven tribes of the subfamily Papilionoideae and two tribes of the subfamily Mimosoideae and Caesalpinoideae. Ureides were found in almost all the plant species studied but for many species in very low concentrations. High ureide content was found in nodules, root and stem of legume species belonging to tribe Phaseolus, subfamily Papilionoideae. Those plants are common in tropical regions, have determinant type of nodules and probably evolved towards a form of transport of nitrogen adapted to warm environments. The high ureide contents of these plants were related to high nitrogenase activities of nodules and reflected the origin of ureides from biological nitrogen fixation.

Foram estudadas 36 espécies de leguminosas representando sete tribos da subfamília Papilionoideae e duas tribos da subfamília Mimosoideae e Caesalpinoideae. Foram encontrados ureídos em quase todas as espécies estudadas, mas muitas espécies possuíam concentração de ureídos muito baixa. Foram encontradas altas concentrações de ureídos em nódulos, raízes e caule de espécies pertencentes à tribo Phaseoleae subfamília Papilionoideae. Essas plantas são encontradas em regiões tropicais, possuem nódulos do tipo determinado e provavelmente desenvolveram uma forma de transporte de nitrogênio adaptada a ambientes quentes. As concentrações elevadas de ureídos nessas plantas foram relacionadas com alta atividade da nitrogenase nos nódulos, o que reflete a origem dos ureídos a partir da fixação de nitrogênio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGoi, Silvia ReginaNeves, Maria Cristina Prata2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15527Pesquisa Agropecuaria Brasileira; v.17, n.1, jan. 1982; 43-50Pesquisa Agropecuária Brasileira; v.17, n.1, jan. 1982; 43-501678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15527/9494info:eu-repo/semantics/openAccess2014-04-15T19:45:17Zoai:ojs.seer.sct.embrapa.br:article/15527Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:45:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
