S-adenosyl-L-methionine | Zea mays | in agreement with the increased secretion of phytosiderophores with Fe deficiency, ZmNAS1 and ZmNAS2 are positively expressed only in Fe-deficient roots. In contrast ZmNAS3 is expressed under Fe-sufficient conditions, and is negatively regulated by Fe deficiency | ? | - |
