Molecular Technique as A Vigorous Instrument for Identification and Classification of Dickeya on The Ornamental Plants

Information on the genetic diversity of pathogenic bacteria causing plant disease is rare to find. This study aims identify and classify disease-causing pathogens in several ornamental plants molecularly. Sixteen bacterial strains were isolated from carnation, chrysanthemum, kalanchoe. All grouped D. dianthicola although carnation kalanchoe gave different results identified strains. The differences found rep-PCR 16S rDNA. Band patterns produced by rep-ERIC PCR revealed that strains, chrysanthemum formed slightly Meanwhile, sequence analysis rDNA separately Even though they positioned independently other but have closely related each thus are as a specific group dianthicola. However, based multilocus (MLSA) dnaX, recA, gyrB rpoD, all into Furthermore, result pathogenicity test showed potato, not
