Abstract
Genome-wide expression profiles of the phytopathogenic actinomycete Clavibacter michiganensis subsp. michiganensis (Cmm) strain NCPPB382 were analyzed using a 70mer oligonucleotide microarray. Cmm causes bacterial wilt and canker of tomato, a systemic disease leading to substantial economic losses worldwide. Global gene expression was monitored in vitro after long-and short-term incubation with tomato homogenate to simulate conditions in planta and in vivo ten days after inoculation of tomatoes. Surprisingly, both in the presence of tomato homogenate and in planta known virulence genes (celA, chpC, ppaA/C) were down-regulated indicating that the encoded extracellular enzymes are dispensable in late infection stages where plant tissue has already been heavily destroyed. In contrast, some genes of the tomA-region which are involved in sugar metabolism showed an enhanced RNA-level after permanent growth in supplemented medium. Therefore, these genes may be important for utilization of plant derived nutrients. In the plant Cmm exhibited an expression profile completely different from that in vitro. Especially, the strong expression of genes of the wco-cluster (extracellular polysaccharide II), 10 genes encoding surface or pilus assembly proteins, and CMM_2382, coding for a putative perforin suggest a possible role of these genes in the plant-pathogenic interaction.
