Brenneria

Abstract

Bren.ne'ri.a. N.L. fem. n. Brenneria named after the American bacteriologist Don J. Brenner. Proteobacteria / Gammaproteobacteria / Enterobacterales / Pectobacteriaceae / Brenneria 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, and walnut and are also associated with disease‐causing species of Lonsdalea . Cells are Gram‐negative, facultatively anaerobic, motile, and short rods, which appear singly or rarely in pairs. Species are mesophilic, favoring 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. The major fatty acids are C 16:0 , C 18:1 ω7 c , C 17:0 cyclo, and summed features 2 (iso‐C 16:1 and/or C 14:0 3‐OH) and 3 (C 16:1 ω7 c and/or iso‐C 15:0 2‐OH). DNA G + C content (mol%) : 51.1–56.2 ( T m and genome analysis). Type species : Brenneria salicis Hauben et al. 1998, VL68 (basonym: “ Bacterium salicis ” Day 1924).

Polyphasic study of phytopathogenic bacterial strains associated with deep bark canker of walnut in Serbia revealed a new species, Brenneria izbisi sp. nov

“…Although 16S rRNA gene and MLSA phylogenies indicated that B. izbisi strains belong to the genus Brenneria , this genus was polyphyletic in these phylogenetic trees. Polyphyly of the genus Brenneria in 16S rRNA gene phylogenetic tree has been observed previously ( Brady and Coutinho, 2021 ). Therefore, we performed phylogenomic analysis based on a large number of non-recombinant core marker genes derived from whole-genome sequence data, in order to generate a more robust phylogenetic tree.…”

Brenneria tiliae sp. nov., isolated from symptomatic Tilia × moltkei and Tilia × europaea trees in the UK

“…The results obtained were compared against the library RTSBA6 6.21. The FAME composition of the novel species is similar to those reported for Brenneria species [2], with the major fatty acids identified as C 16 : 0 , C 18 : 1 ω 7 c , C 17 : 0 cyclo, and summed features 2 (iso-C 16 : 1 and/or C 14 : 0 3-OH) and 3 (C 16 : 1 ω7 c and /or C 16 : 1 ω6 c ). The complete fatty acid profile is presented in .…”

“…The novel species shares all the common phenotypic traits that are typical for the genus Brenneria [2]. The phenotypic results also demonstrated that strains of the novel Brenneria species can be differentiated from its closest phylogenetic neighbours by reactions to acetoin, inositol, sorbitol, melibiose, glycerol, d -mannose, cellobiose, potassium 2-ketogluconate, d -serine, glucuronamide, α-hydroxy-butyric acid and α-keto-butyric acid (differentiation from B.…”

“…[1]. In the following years, several novel Brenneria species were described and the genus currently consists of eight validly published bacterial species that are renowned for their ability to cause disease on woody hosts such as willow, alder, poplar, oak and walnut [2]. Common disease symptoms caused by Brenneria species include bleeding cankers with dark exudate and tissue necrosis, wilt and watermark [3–6].…”
