| 英文摘要 | Oxygen effects have long been ambiguous: exacerbating, being indifferent to, or ameliorating the net photoinactivation of Photosystem II (PS II). We scrutinized the time course of PS II photoinactivation (characterized by rate coefficient k(i)) in the absence of repair, or when recovery (characterized by k(r)) occurred simultaneously in CO2 +/- O-2. Oxygen exacerbated photoinactivation per se, but alleviated it by mediating the utilization of electrons. With repair permitted, the gradual net loss of functional PS II during illumination of leaves was better described phenomenologically by introducing tau, the time for an initial k(r) to decrease by half. At 1500 mu mol photons m(-2) s(-1), oxygen decreased the initial k(r) but increased tau. Similarly, at even higher irradiance in air, there was a further decrease in the initial k(r) and increase in tau. These observations are consistent with an empirical model that (1) oxygen increased k(i) via oxidative stress but decreased it by mediating the utilization of electrons; and (2) reactive oxygen species stimulated the degradation of photodamaged D1 protein in PS II (characterized by k(d)), but inhibited the de novo synthesis of D1 (characterized by k(s)), and that the balance between these effects determines the net effect of O-2 on PS II functionality. |
