Abstract

SUMMARY: sp. isolate UV3, when added to conidial suspensions of , stimulated germination and appressorium formation on glass slides and on host surfaces. A siderophore (S), purified from low-iron culture of the bacteria, stimulated germination and appressorium formation to a significantly greater extent than the bacterial cells alone. The fully chelated siderophore (SFe) and free ferric iron were inhibitory to germination and appressorium formation but inhibited only the latter . The S is compared with nutrients at similar concentrations, and the role of the phytoplane microflora and associated siderophores is discussed in relation to fungal infection.
