| The phenotypic characteristics and genetic fingerprints of a collection of 120 bacterial strains, belonging to Pseudomonas syringae sensu lato group, P. viridiflava and reference bacteria were evaluated, with the aim of species identification. The numerical analysis of 119 nutritional characteristics did not show patterns that would help with identification. Regarding the genetic fingerprinting, the results of the present study supported the observation that BOX-PCR seems to be able to identify bacterial strains at species level. After numerical analyses of the bar-codes, all pathovars belonging to each one of the nine described genomospecies were clustered together at a distance of 0.72, and could be separated at genomic species level. Two P. syringae... |

| Tendo em vista as diversas atividades biológicas apresentadas pelos óleos essenciais e o potencial antibacteriano do óleo essencial de Lippia sidoides Cham., objetivou-se, com este trabalho, caracterizar o óleo essencial desta espécie coletada na região sul do estado de Minas Gerais-Brasil, bem como identificar as suas estruturas secretoras e avaliar sua atividade antimicrobiana sobre as fitobactérias Clavibacter michiganensis subsp. Michiganensis, Xanthomonas vesicatoria e Pseudomonas syringae pv. tomato. As plantas foram coletadas no município de Itumirim e os óleos essenciais de suas folhas, extraídos por hidrodestilação, utilizando-se um aparelho de Clevenger modificado. O óleo essencial apresentou como constituintes majoritários o carvacrol (26,44%) e... |

| Abstract: The strains CM-Z19 and CM-Z6, which are capable of highly degrading chlorpyrifos-methyl, were isolated from soil. They were identified as Bacillus megaterium CM-Z19 and Pseudomonas syringae CM-Z6, respectively, based on the 16S rRNA and an analysis of their morphological, physiological and biochemical characteristics. The strain CM-Z19 showed 92.6% degradation of chlorpyrifos-methyl (100 mg/L) within 5 days of incubation, and the strain CM-Z6 was 99.1% under the same conditions. In addition, the degradation characteristics of the two strains were compared and studied, and the results showed that the strain CM-Z19 had higher phosphoesterase activity and ability to degrade the organophosphorus pesticide than did the strain CM-Z6. However, the... |

| ABSTRACT Pseudomonas syringae pv. actinidifoliorum causes necrotic spots on the leaves of Actinidia deliciosa and Actinidia chinensis. P. syringae pv. actinidifoliorum has been detected in New Zealand, Australia, France and Spain. Four lineages were previously identified within the P. syringae pv. actinidifoliorum species group. Here, we report the draft genome sequences of five strains of P. syringae pv. actinidifoliorum representative of lineages 1, 2 and 4, isolated in France. The whole genomes of strains isolated in New Zealand, representative of P. syringae pv. actinidifoliorum lineages 1 and 3, were previously sequenced. The availability of supplementary P. syringae pv. actinidifoliorum genome sequences will be useful for developing molecular tools... |
