| dc.description | During the last 20 years multiple roles of the nitric oxide gas (•NO) have been uncovered in
plant growth, development and many physiological processes. In seed plants the enzymatic
synthesis of •NO is mediated by a nitric oxide synthase (NOS)-like activity performed by a
still unknown enzyme(s) and nitrate reductase (NR). In green algae the •NO production has
been linked only to NR activity, although a NOS gene was reported for Ostreococcus tauri
and O. lucimarinus, no other Viridiplantae species has such gene. As there is no information
about •NO synthesis neither for non-vascular plants nor for non-seed vascular plants, the interesting
question regarding the evolution of the enzymatic •NO production systems during
land plant natural history remains open. To address this issue the endogenous •NO production
by protonema was demonstrated using Electron Paramagnetic Resonance (EPR). The
•NO signal was almost eliminated in plants treated with sodium tungstate, which also reduced
the NR activity, demonstrating that in P. patens NR activity is the main source for
•NO production. The analysis with confocal laser scanning microscopy (CLSM) confirmed
endogenous NO production and showed that •NO signal is accumulated in the cytoplasm of
protonema cells. The results presented here show for the first time the •NO production in a
non-vascular plant and demonstrate that the NR-dependent enzymatic synthesis of •NO is
common for embryophytes and green algae. | es_MX |
