Anti-phytopathogenic compositions

Abstract

The present invention relates to an isolated bacterium and composition comprising same having anti-pathogenic activity. The invention further relates to compounds derived from said bacterium or analogs thereof, and methods of using same for treating or reducing the symptoms of a pathogen including but not limited to a phytopathogen.

What is claimed is: 
     
         1 . An isolated bacterium comprising a nucleic acid sequence having at least 98% sequence identity to: SEQ ID NO: 1 and at least one additional nucleic acid sequence having at least 85% sequence identity to any one of SEQ ID NO: 2-14. 
     
     
         2 . The isolated bacterium of  claim 1  comprising the nucleic acid sequences as set forth in SEQ ID NO: 2-14. 
     
     
         3 . The isolated bacterium of  claim 1 , comprising a nucleic acid sequence having at least 10% sequence variety to:  Dyella ginsengisoli.    
     
     
         4 . A composition comprising the bacterium of  claim 1  and any one of an emulsifier, a growth substrate, a fertilizer, a herbicide, a pesticide or their combination. 
     
     
         5 . The composition of  claim 4 , wherein said emulsifier comprises a material selected from the group consisting of: a non-ionic surfactant, an anionic surfactant, a cationic surfactant or an amphiphilic surfactant. 
     
     
         6 . The composition of  claim 4 , wherein said emulsifier is a non-ionic surfactant. 
     
     
         7 . The composition of  claim 4 , wherein said growth substrate comprises a selective bacterial growth medium comprises one or more materials selected from the group consisting of a sugar and an amino acid. 
     
     
         8 . The composition of  claim 7 , wherein said sugar is selected from the group consisting of: arabinose, mannose, sucrose, melibiose, galactose, inositol, glucoside, and any combination or derivative thereof; and wherein said amino acid is selected from the group consisting of: proline nitroanilide, γ-L-glutamyl p-nitroanilide, phenylalanine, glycine, arginine, and any combination thereof. 
     
     
         9 . The composition of  claim 4 , further comprising one or more compounds selected from the group consisting of: Quinolinecarboxaldehyde, and Hydroxymethyl-2-furaldehyde, or any derivative thereof.
