Relationships of the genera in the Enterobacteriaceae containing plant pathogenic species: Brenneria, Dickeya, Enterobacter, Erwinia, Pantoea, Pectobacterium, and Samsonia, were investigated by comparison of their nucleotide and peptide sequences of atpD, carA, recA, and the concatenated sequences. Erwinia spp. and Pantoea spp., with Pectobacterium cypripedii, formed a group distinct from other...

Abstract The phenomenon of hhh Europe has been observed for over 100 years. In this time, many attempts have made to describe considering biotic, abiotic and anthropogenic factors. Recently, an increasing intensity bacterial tree diseases both in around the world. Moreover, climate change is contributing increase range pathogens. aim publication was highlight most important occurring on oaks wo...

Members of the genus Erwinia are primarily plant-pathogenic and plant-associated bacteria. As modern approaches have focused on the direct analysis of genes and their gene products, commonly associated phenotypes such as the type of disease that they cause and the relatedness of rDNA have prompted splitting of certain Erwinia members into the genus Enterobacter, Pectobacterium, Pantoea or Brenn...

Two bacteria identified as Lonsdalea quercina subsp. quercina were isolated from oak trees showing symptoms of drippy blight. Here, we present their draft genome assemblies, as well as that of the type strain of this species. To our knowledge, these are the first published genome sequences of this subspecies of Lonsdalea quercina.

Recent examination of the relationships of the dry necrosis-inducing (necrogenic) erwinias using 16S rDNA sequences demonstrated that these bacteria comprise a polyphyletic group and, therefore, have been subdivided into three distinct genera, Erwinia, Brenneria and Pectobacterium, with the classical 'amylovora' group species now being distributed nearly evenly among the first two. To further a...

In recent time, there is a major concern about antibiotic resistance displayed by some pathogenic microorganisms and this had involved a continuous search for natural antimicrobial products. The phytochemistry as well as antimicrobial activity of extracts obtained from Lenzites quercina was investigated. The extracts and purified fractions were, respectively, tested against indicator organisms ...
