87,735 | Regulation of nitric oxide emissions from forest and rangeland soils of western North America | Stark, JM; Smart, DR; Hart, SC; Haubensak, KA | 2,002 | #Nitric oxide (NO) is a relatively short-lived trace gas that reacts with oxygen in the troposphere to produce the air pollutant ozone. It also reacts with water vapor to form nitric and nitrous acids, which acidify precipitation and increase N deposition. Models currently used to predict soil NO fluxes are based on th... | 0 |

35,257 | Nitric oxide interferes with plant photo-oxidative stress by detoxifying reactive oxygen species | Beligni, M; Lamattina, L | 2,002 | Oxidative stress within chloroplasts is originated due to light-dependent O(2) reduction. This may be exacerbated by bipyridinium herbicides, which act at photosystem I as artificial electron acceptors. Their oxidation produces a superoxide anion that further dismutates to H(2)O(2) and then, by the Fenton reaction, H(2... | 0 |
