Abstract To incite a systemic disease on its specific host, Saintpaulia ionantha, the soft-rot Erwinia chrysanthemi strain 3937 requires a functional high affinity iron transport system. Under iron starvation, strain 3937 produces chrysobactin, a novel catechol-type siderophore. Recent advances in the biochemistry and genetics of iron assimilation in E. chrysanthemi are reported. Analysis of leaf intercellular fluid from healthy and infected plants suggests: (i) leaf vessels in which the bacteria develop during infection would be low in free iron and (ii) chrysobactin could be produced in planta.
