Outline of Final Research Achievements

Four microbial artificial siderophores have been synthesized and investigated on the function as alkali-resistant iron supply agents for plant. Giving these four artificial siderophores to seedlings of grape tomato made to iron starvation, the iron concentration in their shoot and root recovered. This result indicates that these artificial siderophores act as iron supply agents for plants. Furthermore, one of them showed the recovery from iron starvation for rice mutant that is not able to synthesize phytosiderophores in an alkali soil.
