Disruption of comA homolog in Ralstonia solanacearum does not impair its twitching motility.

Ralstonia solanacearum is an important phyto-pathogenic bacterium. The bacterium exhibits type IV pili meditated twitching motility that has been implicated in the process of natural transformation in it. A comA gene homolog, alike in several other naturally competent bacteria, has been already reported in this bacterium.
