Inhibition of the activity of photosystem II (PSII) under strong light is referred to as photoinhibition. This phenomenon is due to the imbalance between the rate of photodamage to PSII and the rate of the repair of damaged PSII. Photodamage is initiated by the direct effects of light on the oxygen-evolving complex and, thus, photodamage to PSII is unavoidable. Studies of the effects of oxidative stress on photodamage and subsequent repair have revealed that reactive oxygen species (ROS) act primarily by inhibiting the repair of photodamaged PSII and not by damaging PSII directly. Thus, strong light has two distinct effects on PSII; it damages PSII directly and it inhibits the repair of PSII via production of ROS. Investigations of the ROS-induced inhibition of repair have demonstrated that ROS suppress the synthesis de novo of proteins and, in particular, of the D1 protein, that are required for the repair of PSII. Moreover, a primary target for inhibition by ROS appears to be the elongation step of translation. Inhibition of the repair of PSII by ROS is accelerated by the deceleration of the Calvin cycle that occurs when the availability of CO(2) is limited. In this review, we present a new paradigm for the action of ROS in photoinhibition.

Increased rate of D1 repair in coral symbionts during bleaching is insufficient to counter accelerated photo‐inactivation (2011, background): “Our data thus show that increased susceptibility to photo-inactivation, rather than an inhibition of PSII repair (Nishiyama et al. 2006), is the principal trigger for net photo-inhibition of PSII activity under these bleaching conditions in hospite, in contrast to the recent findings of Takahashi…”

Green light drives leaf photosynthesis more efficiently than red light in strong white light: revisiting the enigmatic question of why leaves are green.

Correlation between reactive oxygen species production and photochemistry of photosystems I and II in Lemna gibba L. plants under salt stress (2015, background): “In previous studies, it has been reported that salt stress reduced thylakoid membrane protein, D1 and ROS do not accelerate photodamage to PSII but inhibit the repair of PSII by suppressing primarily the synthesis of proteins de novo (Allakhverdiev and Murata, 2004; Nishiyama et al., 2006).”
