Opposing Expression and Activities of NR, an Nt-Cys Artificial Substrate, and ERFVIIs

(A) Destabilization of C-^HAGUS in Arabidopsis nia1 nia2 by the NO donor SNAP.

(B) NR activity in Arabidopsis 3-day-old seedlings transferred to 150 mM NaCl for 7 days and then returned to control media for 3 days (3R).

(C) NO levels (measured as DAF-2DA fluorescence, arbitrary units) and histochemical visualization of C-^HAGUS after 4 days growth on 150 mM NaCl or control media.

(D) NR activity and GUS protein levels in response to watering with NaCl in Arabidopsis (200 mM) and barley (300 mM).

(E) Root length of Arabidopsis seedlings at increasing time following germination.

(F) Flowering time (days) and leaves at flowering of Arabidopsis plants.
