BACKGROUND Britain's native oak species are currently under threat from acute oak decline (AOD), a decline-disease where stem bleeds overlying necrotic lesions in the inner bark and larval galleries of the bark-boring beetle, Agrilus biguttatus, represent the primary symptoms. It is known that complex interactions between the plant host and its microbiome, i.e. the holobiont, significantly infl...

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...

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...

Acute Oak Decline (AOD) is complex syndrome affecting Britain’s keystone native oak species, (Quercus robur L. and Q. petraea (Matt.) Liebl.), in some cases causing mortality within five years of symptom development. The most distinguishable weeping stem lesions, from which four species bacteria have been isolated: Brenneria goodwinii, Gibbsiella quercinecans, Lonsdalea britannica Rahnella vict...

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...

In 2008, a global production rounding 1,724 and 1,053 million metric tones respectively for walnut and hazelnut has been estimated. Bacterial diseases are threatening these nut crops all over the World. Xhanthomonas arboricola pv. juglandis (Xaj) is the agent of walnut bacteriosis, and has been associated also to brown apical necrosis. Several walnut genotypes have shown a range of tolerance to...

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...

Bacillus muralis LMG 20238(T) is a Gram-positive, aerobic, and spore-forming bacterium. Here, we report the 5.18-Mb draft genome sequence of B. muralis LMG 20238(T), which is the first genome sequence of this species and will promote its fundamental research.
