Bacterial Communities Associated With Acute Oak Decline of Sessile Oak (Quercus petraea) in Southern Sweden.

ABSTRACT: Acute oak decline (AOD) is a rapidly progressing disease affecting various oak species (Quercus spp.). Recent studies have shown that AOD is associated with a consortium of Gram-negative, facultatively anaerobic bacteria (e.g., in Enterobacterales) in the United Kingdom and continental Europe. However, there is limited information on the bacterial contributions and key genera associated with oak diseases and broadleaf forest ecosystems in Nordic countries. The primary objective of this brief study was to collect the first data on the bark microbiomes of symptomatic, declining sessile oaks (Q. petraea) in Sweden. Pairs of healthy and diseased bark samples were collected from symptomatic trees near Ankarsrum (Kalmar County), Sweden. After total DNA extraction, the bacterial 16S rDNA region w
