Outline of Final Research Achievements

The mechanism on respiration and riboflavin secretion working under Fe deficiency in Fe deficiency-tolerant Hyoscyamus albus roots was studied. Proteomic analysis showed that the mitochondrial complex I which requires high amounts of Fe was decreased under Fe deficiency. Riboflavin secretion occurred by both the enhancements of FMN hydrolysis and de novo synthesis of riboflavin. An increase of respiration activity was closely related to riboflavin secretion, too. Many metabolic pathways were changed into Fe- and energy-saving manners: instead, they utilized Fe and energy for more essential growth. As a morphological change, root-tip swelling has been observed. Nondestructive histochemical analysis with a laser microscope revealed that the enlargement of cell width and rhizodermal development contributed to this phenomenon. Increase in cell surface area must help to acquire Fe.
