Suppression of Damping-Off Disease in Host Plants by the Rhizoplane Bacterium Lysobacter sp. Strain SB-K88 Is Linked to Plant Colonization and Antibiosis against Soilborne Peronosporomycetes
ABSTRACT We previously demonstrated that xanthobaccin A from the rhizoplane bacterium Lysobacter sp. strain SB-K88 suppresses damping-off disease caused by Pythium sp. in sugar beet. In this study weExpand

Possible Role of Xanthobaccins Produced byStenotrophomonas sp. Strain SB-K88 in Suppression of Sugar Beet Damping-Off Disease
ABSTRACT Three antifungal compounds, designated xanthobaccins A, B, and C, were isolated from the culture fluid of Stenotrophomonassp. strain SB-K88, a rhizobacterium of sugar beet that suppressesExpand

Isoflavonoids produced by Iris pseudacorus leaves treated with cupric chloride
Abstract Iris pseudacorus leaves treated with cupric chloride produced fungitoxic stress metabolites. They were found to be 10 isoflavones [5,2′-dihydroxy-6,7-dimethoxyisoflavone (irilin A),Expand

Enzymatic nitration of phytophenolics: evidence for peroxynitrite‐independent nitration of plant secondary metabolites
Peroxynitrite (ONOO−), a reactive nitrogen species, is capable of nitrating tyrosine residue of proteins. Here we show in vitro evidence that plant phenolic compounds can also be nitrated by anExpand

High Rate of N2 Fixation by East Siberian Cryophilic Soil Bacteria as Determined by Measuring Acetylene Reduction in Nitrogen-Poor Medium Solidified with Gellan Gum
ABSTRACT For evaluating N2 fixation of diazotrophic bacteria, nitrogen-poor liquid media supplemented with at least 0.5% sugar and 0.2% agar are widely used for acetylene reduction assays. In such aExpand
