Dual nitrogen species involved in foliar uptake of nitrogen dioxide in Arabidopsis thaliana

Figures & data

Table 1. Total, reduced, and ammonium nitrogen (N) derived from nitrogen dioxide (NO₂) in Arabidopsis leaves treated with methionine sulfoximine (MSX) (or left untreated) and exposed to 4 ppm¹⁵N-labeled NO₂ for 4 h in the light.

MSX	Total N derived from NO2 (ng/g dry weight)	Reduced N derived from NO2 (ng/g dry weight)	Ammonium N derived from NO2 (ng/g dry weight)
–	540.0	357.6	31.7
+	286.0	196.0	172.0
