Plant use of iron depends on the plant s ability to respond chemically to iron stress. This response causes the roots to release H+ and deduct ants, to reduce Fe3+, and to accumulate citrate, making iron available to the plant. Reduction sites are principally in the young lateral roots. Azide, arsenate, zinc, copper, and chelating agents may interfere with use of iron. Chemical reactions induced by iron stress affect nitrate reductase activity, use of iron from Fe3+ phosphate and Fe3+ chelate, and tolerance of plants to heavy metals. The iron stress-response mechanism is adaptive and genetically controlled, making it possible to tailor plants to grow under conditions of iron stress. 

Several decades ago, the earliest genetic work in molybdenum enzymes identified mutants of two fungi, Aspergillus nidulans (125) and Neurospora crassa (126) that lacked all molybdenum enzyme activities, specifically, nitrate reductase, XDH, and aldehyde oxidase. The mutant N. crassa produces an...
