UV-induced formation of filamentous forms in bacteria of Erwinia genus

Cells of 56 pectolytic Erwinia strains of different origin tested are prone to filamentation after UV-irradiation. The fact makes one possible to consider them natural fil+ organisms. Bacteria E. herbicola (9 strains) that are unable to synthesize pectatelyases are not transformed into filaments aft...

Summary:Cells of 56 pectolytic Erwinia strains of different origin tested are prone to filamentation after UV-irradiation. The fact makes one possible to consider them natural fil+ organisms. Bacteria E. herbicola (9 strains) that are unable to synthesize pectatelyases are not transformed into filaments after NV-irradiation. The function of fil+ genes is recA-dependent in bacteria E. chrysanthemi ENA49 and is phenotypically analogous to fil+ gene function in E. coli B or lon- mutation in E. coli K12.
