Abstract

Abstract Pantoea citrea,the causal agent of pink disease of pineapple, harbors a cryptic plasmid of 5229 bp, designated pUCD5000. On the basis of nucleotide and amino acid sequence analyses, pUCD5000 contains both replication and mobilization loci ( bomand mobCABD) that are similar to those in plasmids pSW100 and pSW200 in Pantoea stewartiiand pEC3 in Erwinia carotovorasubsp. carotovora.The survival of P. citreaon pineapple does not depend on pUCD5000. However, full pink coloration development, which is characteristic of the pink disease, appears to require this plasmid.
