Germination-defective mutant of Neurospora crassa that responds to siderophores

Abstract
A conditionally germination-defective mutant of N. crassa was partially curable by ferricrocin and other siderophores. The mutant conidia rapidly lose their membrane-bound siderophores when suspended in buffer or growth media. Germination is consequently delayed unless large numbers of conidia are present (positive population effect). This indicates that the mutant has a membrane defect involving the siderophore attachment site.
