| 英文摘要 | The biomasses, rate of apparent nitric oxide (NO)-release, nitric oxide synthase (NOS) activity as well as beta-d-endo and exo-glucanase activity of the cell wall were analyzed and determined in the roots of maize seedlings. It was found that rhizospheric treatments of 2-phenyl-4,4,5,5-tetramethlimida-zoline-l-oxyl-3-oxide (PTIO), a NO scavenger, and radiation of enhanced ultraviolet-B (UV-B) to aerial parts of the seedling markedly inhibited the rate of NO release in roots, raised the activity of beta-d-endo and exo-glucanase, and increased the biomasses of roots. The patent inhibitor, N-nitro-l-arginine (LNNA), of NOS was unable to inhibit NOS activity and NO generation. Inversely, reactive oxygen species (ROS) eliminator, N-acetyl-cysteine (NAC), stimulated the rate of NO release. There is no relationship between NOS activity and the rate of NO release. The latter showed a positive correlation with nitrate reductase (NR) activity, whereas it showed a negative correlation with the bio-masses and the activity of beta-d-endo and exo-glucanase. All results implicated that NO was a by-product generated by NR catalysis, whereas NR activity was sensitively repressed by the systemic signal network (involved in ROS) induced by enhanced UV-B. It indicated that the downstream signal molecule of enhanced UV-B light is probably ROS which decreased NO generation through inhibiting NR activity. The endogenous NO generated by NR catalysis is perhaps such a messenger for restraining beta-d-endo and exo-glucanase activity that the root growth was retarded. |
