Suppression of Root Diseases by Pseudomonas fluorescens CHA0: Importance of the Bacterial Secondary Metabolite 2,4-Diacetylphloroglucinol
Christoph Keel,Ursula Schnider,Monika Maurhofer,Christophe Voisard,Jacques Laville,Ulrich Burger,P. Wirthner,Dieter Haas,Geneviève Défago +8 more
TL;DR: Pseudomonas fluorescens strain CHAO suppresses Thielaviopsis basicola-induced black root rot of tobacco and Gaeumannomyces graminis var. tritici-induced take-all of wheat.
Journal Article
Pseudomonads as antagonists of plant pathogens in the rhizosphere: role of the antibiotic 2,4-diacetylphloroglucinol in the suppression of black root rot of tobacco.
Christoph Keel,P. Wirthner,Thomas Oberhänsli,Christophe Voisard,Ulrich Burger,Dieter Haas,Geneviève Défago +6 more
TL;DR: Results suggest that the production of 2,4-diacetylphloroglucinol by P. fluorescens strain CHA0 is another important factor, in addition to cyanide, in the suppression of black root rot of tobacco.

Journal ArticleDOI
Involvement of nodS in N-Methylation and nodU in 6-O-Carbamoylation of Rhizobium sp. NGR234 Nod Factors
Said Jabbouri,Remy Fellay,Franck Talmont,Philippe Kamalaprija,Ulrich Burger,Biserka Relic,Jean-Claude Promé,William J. Broughton +7 more
TL;DR: Nod factor levels, their degree of oligomerization, and N-methylation are linked to the activity encoded by nodS, and they are identical to those of the wild-type strain.
Journal ArticleDOI

TL;DR: In this paper, two pairs of enantiomerically pure cis-fused cyclopenteno-1,2,4-trioxanes (7, ent-7,8, and ent-8) are prepared and their identities are established by dye-sensitized photo-oxygenation.
