formation of MAs induced by iron deficiency in wheat:
nicotinamide aminotransferase gene (Naat), nicotinamide
synase gene (Nas), formic dehydrogenase gene
(Fdh), adenine phosphoribosyl transferase gene (Aprt),
alcohol dehydrogenase gene (Adh) [16]. The known
identity of Ids and these genes make the biosynthesis of
the iron carriers conceivable. Moreover, the highly
efficient Fe3+PS absorption system on root membranes
of gramineous plants can enhance iron absorption
