    Notes: Summary A concise history of selected aspects of iron metabolism is presented. According to present understanding, the element is known to be required for transport and reduction of O2, for reduction Of CO2, N2 and ribonucleotides, and for other essential cellular processes. The contributions of pioneers in the field, preeminent among them the cell physiologist and biochemist Otto Warburg, are recounted.

    Notes: 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.
