Abstract
Alkaline soils comprise 30% of the earth and have low plant-available iron concentrations. Thus, alkaline stress can cause iron deficiency chlorosis (IDC). It is not known whether the physiological and molecular responses to IDC resulting from alkaline stress are equivalent to those resulting from low iron supply. There is genetic variation for severity of IDC symptoms in cucumber (Cucumis sativus) and soybean (Glycine max), but the specific basis for IDC tolerance is not known. IDC tolerant and sensitive lines provide a contrast to identify specific factors associated with IDC and to understand regulation of gene expression by iron limitation and alkaline stress. This work could result in new strategies to screen for IDC tolerance, and provide breeding targets to improve crop alkaline stress tolerance.
