    Cultivares de soja com elevado potencial produtivo sĂŁo requeridas todos os anos pelos agricultores. A Embrapa Soja vem desenvolvendo cultivares de soja produtivas e adaptadas Ă s diferentes regiĂ”es edafoclimĂĄticas do Brasil. O objetivo deste trabalho Ă© apresentar a cultivar BRS PĂ©rola, desenvolvida pela Embrapa Soja em convĂȘnio com a Fapcen, indicada para o cultivo nos estados do MaranhĂŁo, norte do Tocantins e sudoeste do PiauĂ­. A BRS PĂ©rola Ă© uma cultivar de soja convencional, do grupo de maturidade relativo 8.8, tipo de crescimento determinado, flor branca, pubescĂȘncia marrom mĂ©dio e cor de hilo marrom. Nas safras 2007/08, 2008/09, 2009/10 e 2010/11 ela foi avaliada em experimentos de Valor de Cultivo e Uso em diferentes locais no MA, PI, TO, decidindo-se entĂŁo pelo seu lançamento. A cultivar apresenta elevado potencial produtivo, ficando acima das trĂȘs cultivares testemunhas utilizadas nos experimentos (BRS TracajĂĄ, M-Soy 8866 e P98C81), com rendimento mĂ©dio de 3.652 kg/ha, ao passo que a mĂ©dia das testemunhas foi de 3.436 kg/ha, indicando ainda resistĂȘncia Ă s principais doenças da soja e estabilidade na altura de plantas, proporcionando a sua semeadura em ĂĄreas de baixas altitudes. A BRS PĂ©rola Ă© uma excelente opção de cultivar de soja convencional para o mercado

    A deeply branching thermophilic bacterium with an ancient acetyl-CoA pathway dominates a subsurface ecosystem

    <div><p>A nearly complete genome sequence of <em>Candidatus</em> ‘Acetothermum autotrophicum’, a presently uncultivated bacterium in candidate division OP1, was revealed by metagenomic analysis of a subsurface thermophilic microbial mat community. Phylogenetic analysis based on the concatenated sequences of proteins common among 367 prokaryotes suggests that <em>Ca.</em> ‘A. autotrophicum’ is one of the earliest diverging bacterial lineages. It possesses a folate-dependent Wood-Ljungdahl (acetyl-CoA) pathway of CO<sub>2</sub> fixation, is predicted to have an acetogenic lifestyle, and possesses the newly discovered archaeal-autotrophic type of bifunctional fructose 1,6-bisphosphate aldolase/phosphatase. A phylogenetic analysis of the core gene cluster of the acethyl-CoA pathway, shared by acetogens, methanogens, some sulfur- and iron-reducers and dechlorinators, supports the hypothesis that the core gene cluster of <em>Ca.</em> ‘A. autotrophicum’ is a particularly ancient bacterial pathway. The habitat, physiology and phylogenetic position of <em>Ca.</em> ‘A. autotrophicum’ support the view that the first bacterial and archaeal lineages were H<sub>2</sub>-dependent acetogens and methanogenes living in hydrothermal environments.</p> </div
