Resumo: Experiments with Phaseolus vulgaris L. grown in sand irrigated with N-free nutrient solution were conducted to evaluate the mutagenic stability, infectivity, and N2-fixing ability of R. phaseoli spontaneous mutants resistant to antibiotics and fungicides. There were variations on resistance levels among the Rhizobium strains to the different biocides. Loss of infective ability or decrease in efficiency for N2 fixation observed for several mutants were not related to the type of antibiotic and fungicide nor to the different concentration used. Some mutant strains exhibited a higher N2-fixing ability when compared to SEMIA 487 and SEMIA 492 which are being used by inoculant manufacturers. The mutant SEMIA 4002-ST1 was mutagenically stable. The results support the idea about the possibility of using spontaneous mutants in ecological of Rhizobium as long as they have mutagenic stability and have no cross-resistance to the antibiotics.

Houve variações nos níveis de resistência entre as estirpes aos diferentes biocidas utilizados. Perdas na capacidade infectiva ou fixadora de N2 dos mutantes de R. phaseoli não estiveram relacionadas com o tipo de antibióticos ou fungicidas, e nem com as concentrações utilizadas. Algumas estirpes mostraram mais capacidade de fixação de N2, em comparação com SEMIA 487 e SEMIA 492, atualmente incluídas entre as estirpes recomendadas aos fabricantes de inoculantes. O mutante SEMIA 4002-ST1 apresentou-se mutagenicamente estável. Os resultados confirmam as proposições quanto à viabilidade de utilização de mutantes em estudos ecológicos de Rhizobium, desde que estes mantenham suas características mutagênicas e não apresentem resistência cruzada aos antibióticos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPereira, João CarlosLovato, Paulo EmilioVidor, Caio2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14773Pesquisa Agropecuaria Brasileira; v.21, n.4, abr. 1986; 383-392Pesquisa Agropecuária Brasileira; v.21, n.4, abr. 1986; 383-3921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14773/8454info:eu-repo/semantics/openAccess2014-10-21T18:43:43Zoai:ojs.seer.sct.embrapa.br:article/14773Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-21T18:43:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
