Transcription of the regulatory gene ros of Agrobacterium radiobacter requires growth in the presence of Fe although this regulation was not mediated by ros itself. The ros gene repressed its own transcription, independently of the Fe status of the growth media. It was shown that the two cysteine residues in the Ros protein were essential for the complementation of the exopolysaccharide synthesis defect of ros...
