摘要

在本研究中，评估了用okadaic酸（OA）处理的番茄幼苗（Solanum lycopersicum cvs.Kmicic和Faworyt）的总和实际硝酸还原酶（NR）活性以及NR激活状态。幼苗在生长室中的半强度Murashige和Skoog（MS）培养基中生长，昼夜温度为22/20°C，光子通量密度为150µmol m-2 s-1，光周期为16小时。10天后，将植物转移到含有0（对照）、0.01、0.05、0.1、0.5、1.0µM OA的MS培养基中。研究发现，与对照相比，用0.1、0.5和1.0µM OA处理的Kmic叶片的总NR活性和实际NR活性增加。然而，OA处理的番茄幼苗的根和叶的NR激活状态都没有改变。

Okadaic acid did not change the nitrate reductase activation state in tomato seedlings

In this study, the total and actual nitrate reductase (NR) activity, and NR activation state, in tomato seedlings ( Solanum lycopersicum cvs. Kmicic and Faworyt) treated with okadaic acid (OA) was evaluated. Seedlings were grown in a half-strength Murashige and Skoog (MS) medium in a growth chamber at day/night temperatures of 22/20 °C, a photon flux density of 150 µmol m -2 s -1 , and a 16-h photoperiod. After 10 days, plants were transferred into MS medium with 0 (control), 0.01, 0.05, 0.1, 0.5, 1.0 µM OA. It was found that the total and actual NR activity increased in Kmicic leaves treated with 0.1, 0.5, and 1.0 µM OA compared to control. However, the NR activation state did not change in both roots and leaves of OA-treated tomato seedlings.

期刊介绍： BIOLOGIA PLANTARUM is an international journal for experimental botany. It publishes original scientific papers and brief communications, reviews on specialized topics, and book reviews in plant physiology, plant biochemistry and biophysics, physiological anatomy, ecophysiology, genetics, molecular biology, cell biology, evolution, and pathophysiology. All papers should contribute substantially to the current level of plant science and combine originality with a potential general interest. The journal focuses on model and crop plants, as well as on under-investigated species.
