Biochemical, Pathological and Genetic Characterization of Strains of Ralstonia solanacearum (Smith) from Ethiopia and Biocontrol of R. solanacearum with Bacterial Antagonists Von der Naturwissenschaftlichen Fakultät der Gottfried Wilhelm Leibniz Universität Hannover zur Erlangung des akademischen Grades eines Doktors der Gartenbauwissenschaften -Dr.rer.hort.- genehmigte Dissertation von Fikre Lemessa Ocho (MSc) geboren am 01.09.1969 in Shambu (Wollega), Oromia, Äthiopien 2006 Referent: Prof. Dr. Wolfgang Zeller Korreferent: Prof. Dr. Matthias Ullrich Tag der Promotion: 06. 07. 2006 Dedicated to my parents Abstract Biochemical, Pathological and Genetic Characterization of Strains of Ralstonia solanacearum (Smith) from Ethiopia and Biocontrol of R. solanacearum with Bacterial Antagonists Fikre Lemessa Ocho Ralstonia solanacearum (Smith) is a very destructive bacterial plant pathogen that causes wilt disease in potato, tomato and other solanaceae crops in Ethiopia. The strains of this heterogeneous bacterial species differ in biochemical, pathogenic and genetic characteristics and no effective control measure has been developed against it yet.
