Siderophores (Greek: "iron carrier") are small, high-affinity iron-chelating compounds that are secreted by microorganisms such as bacteria and fungi. They help the organism accumulate iron. Although a widening range of siderophore functions is now being appreciated, siderophores are among the strongest (highest affinity) Fe3+ binding agents known. Phytosiderophores are siderophores produced by plants.
Pantoea stewartii is a species of plant pathogenic bacteria that causes Stewart's wilt of corn, as well as jackfruit-bronzing disease, bacterial leaf wilt of sugarcane, and leaf blight in rice. P. stewartii is a gram-negative bacterium in the Enterobacterales, a group that also includes Escherichia coli and several other human, animal, and plant pathogens. Most research on this bacterial pathogen to date has been done on strains infecting corn as the other diseases have been identified much more recently. Due to being relatively easy to work with in laboratory research, P. stewartii has been used to study a range of processes in bacterial physiology including quorum sensing, bacterial pigment production, endoglucanase enzymes, and siderophore-mediated iron acquisition.
Xanthomonas campestris is a gram-negative, obligate aerobic bacterium that is a member of the Xanthomonas genus, which is a group of bacteria that are commonly known for their association with plant disease. This species includes Xanthomonas campestris pv. campestris the cause of black rot of brassicas, one of the most important diseases of brasicas worldwide.
