Nitric oxide and glutathione impact the expression of iron uptake- and iron transport-related genes as well as the content of metals in A. thaliana plants grown under iron deficiency [PDF]

open access: yes, 2012
Mounting evidence indicate that nitric oxide (NO) acts as a signaling molecule mediating iron deficiency responses through the up-regulation of the expression of iron uptake-related genes.
