Visible effects of raising internal NO by treating Fe-deficient maize with SNP. (A) Maize plants showing the effect of graded SNP supply: (1) Fe-sufficient control plants (100 µM Fe-EDTA); (2) Fe-deficient control plants (10 µM Fe-EDTA); (3) Fe-deficient plants treated with 10 µM SNP; (4) Fe-deficient plants treated with 50 µM SNP; (5) Fe-deficient plants treated with 100 µM SNP. (B) Plants showing effects of SNP and SF: (1) Fe-sufficient control plants (100 µM Fe-EDTA); (2) Fe-deficient control plants (10 µM Fe-EDTA); Fe-deficient plants treated with (3) 100 µM SNP; (4) 100 µM SF. (C) SNP-treated Fe-deficient plant supplied with the NO scavenger MB. (D) Close-up of MB-treated, SNP-treated Fe-deficient leaf. Close-ups of (E) Fe-sufficient leaf and leaves of Fe-deficient plants treated with (F) 10 µM, (G) 50 µM and (H) 100 µM SNP. (I) Close-up of Fe-deficient leaf. Close-ups of Fe-deficient leaves of plants treated with SF at (J) 10 µM, (K) 50 µM and (L) 100 µM.
