Abstract

Global iron deficiency is one factor contributing to malnutrition and varied health conditions. This deficiency accounts for 841,000 deaths and approximately 35,057,000 “disability-adjusted life years lost” (Stoltzfus, R. J. 2003). One way to combat this is to maintain or increase the iron uptake of the globe’s major crops. Research has shown that certain types of mycorrhizal fungi can increase the nutrient uptake of plants. To further this research, we will look at the arbuscular fungi Rhizophagus irregularis and its potential relationship with a short harvest corn variety. This type of mycorrhizal fungi improves plant nutrition including the plant’s ability to source iron from the natural environment. Much of the iron found in the natural environment is in the form of ferric hydroxide. The Rhizophagus irregularis can convert this form of iron into one that is usable by plants. It is also tolerant of substrates with high levels of heavy metals, even alleviating some of the stress plants undergo in these substrates. The Rhizophagus irregularis should be capable of increasing the iron content in many crop types, including corn varieties. This could be important information in the efforts to relieve global malnutrition, something that will only be exacerbated by climate change.

Research Proposal for An Assessment of the Potential for the Arbuscular Fungi “Rhizophagus irregularis” to Aid in Corn Uptake and Availability of Iron

Global iron deficiency is one factor contributing to malnutrition and varied health conditions.
