In higher plants, only root mitochondria, but not leaf mitochondria reduce nitrite to NO, in vitro and in situ.

Journal of experimental botany - 1 Oct 2005

Gupta Kapuganti Jagadis, Stoimenova Maria, Kaiser Werner M

Abstract excerpt

At oxygen concentrations of < or =1%, even completely nitrate reductase (NR)-free root tissues reduced added nitrite to NO, indicating that, in roots, NR was not the only source for nitrite-dependent NO formation. By contrast, NR-free leaf slices were not able to reduce nitrite to NO. Root NO formation was blocked by inhibitors of mitochondrial electron transport (Myxothiazol and SHAM), whereas NO formation by...
