Iron is abundant in almost all soils, but often in insoluble forms, and plant roots affect iron solubility by one of two strategies. In dicots and the non-grass monocots, iron acquisition is facilitated by a set of mechanisms known as strategy I. These mechanisms include the FRO (ferric reductase oxidase) protein and the IRT (iron regulated transporter) gene. As a strategy I plant, Helianthus annus is expected to be able to take up iron effectively (and in fact to exhibit enhanced capabilities) when internal iron levels are below required amounts, but to reduce the activities of iron acquisition mechanisms when internal iron concentrations are sufficient.

Higher plants are able to develop two different strategies in order to increase iron availability in soils. Strategy I is developed by dicot and non-graminaceous monocot
