Brenneria

Brady, Carrie; Coutinho, Teresa

Abstract

The genus Brenneria was created to accommodate bacteria causing disease on woody hosts. Species cause a range of cankers, wilts and necroses on willow, oak, alder, walnut and are also associated with disease-causing species of Lonsdalea. Cells are Gram-negative, facultativley anaerobic, motile, short rods which appear singly or rarely in pairs. Species are mesophilic, favouring growth temperatures of 28 – 30 °C, and prefer low salt media and neutral pH. Carbon sources such as glucose, fructose, sucrose, galactose and N-acetylglucosamine are readily assimilated and fermented. Species form a monophyletic clade when phylogenetic analysis is based on multilocus sequence analysis (MLSA) or whole genome sequences, while 16S rRNA gene sequence phylogenies indicate that the genus is polyphyletic. Major fatty acids are C16:0, C18:1ω7c, C17:0 cyclo, and summed features 2 (iso-C16:1 and/or C14:0 3-OH) and 3 (C16:1 ω7c and /or iso-C15:0 2-OH) and the DNA G + C content is 51.1 – 56.2 mol % (Tm and genome analysis).
Type species: Brenneria salicis (Day 1924) Hauben et al. 1999VP.
