The complete genome sequence of Chromobacterium violaceum reveals remarkable an...
Vasconcelos, Ana Tereza; De-Almeida, Darcy Fontoura; Hungría, Mariangela; Guimarães, Cláudia Teixeira; Antônio, Regina VasconcellosChromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spre...
Molecular characterization and evaluation of pectinase and cellulase production...
Pereira, Jorge Fernando; Queiroz, Marisa Vieira de; Gomes, Eliane Aparecida; Muro-Abad, Júpiter Israel; Araújo, Elza Fernandes dePenicillium species were analyzed with molecular markers and for pectinase and cellulase production. RAPD and PCR-RFLP analysis indicated high polymorphism among at least 5 of 10 Penicillium species. Five species were chosen for pectinase and cellulase production in liquid medium and four of which appeared similar based on molecular analyses. P. brevicompactum and P. griseoroseum gave the highest pectinase prod...
Genetic diversity of indigenous common bean (Phaseolus vulgaris L.) rhizobia fr...
Torres, Adalgisa Ribeiro; Araújo, Elza Fernandes de; Cursino, Luciana; Muro-Abad, Júpiter Israel; Gomes, Eliane Aparecida; Hungria, MariangelaWe characterized indigenous common bean rhizobia from five districts of the state of Minas Gerais, Brazil. The isolates were trapped by two common bean varieties, the Mineiro Precoce (Andean origin) and Ouro Negro (Mesoamerican origin). Analysis by BOX-PCR of selected isolates detected a high level of genetic diversity.
Caracterização morfológica, genética e patogenicidade de isolados de Rhizoctoni...
Oliveira, Amanda Cabral corrêa; Souza, Paulo Estevão de; Pozza, Edson Ampélio; Figueira, Antônia dos Reis; Avelar, Gabriel DornelasA espécie Rhizoctonia solani é um patógeno importante na cultura do algodão associada a doenças conhecidas como tombamento e mela. A variabilidade entre os isolados são extremamente importantes, porque existem diferenças entre os grupos de anastomose, tomadas como aqueles isolados capazes de trocar informações genéticas entre si. A caracterização morfológica, quando confirmada pela a caracterização genética for...
