Figure 1.
Nitric oxide (NO) released from nitro-linolenic acid (NO2-Ln) in Arabidopsis root seedlings. Representative images illustrating the CLSM in vivo detection of NO (green color) in primary roots of Arabidopsis seedlings pre-incubated with (B) 100 µM of linolenic acid (Ln), (C) nitro-linolenic acid (NO2-Ln) or (D) NO2-Ln in the presence of 100 µM cPTIO. Control samples (A) show untreated endogenous NO content.
