Characterization of thermal damage to the photosynthetic electron transport system in potato leaves
TLDR
Analysis of the characteristics of chlorophyll fluorescence induction in sub- and super-saturating light revealed two targets of mild heat stress: an irreversible inhibition of electron donation to PSII and a reversible reduction of excitation energy trapping by the PSII reaction centers, with the former effect being identified as the major determinant of the loss of photosynthesis.About:

The temperature response of C(3) and C(4) photosynthesis.
Rowan F. Sage,David S. Kubien +1 more
TL;DR: The temperature response of instantaneous net CO(2) assimilation rate (A) is described in terms of these limitations, and possible limitations on A at elevated temperatures arising from heat-induced lability of Rubisco activase are evaluated.
Journal ArticleDOI
Acclimation and adaptive responses of woody plants to environmental stresses
TL;DR: The predominant emphasis on harmful effects of environmental stresses on growth of woody plants has obscured some very beneficial effects of such stresses, including physiological adjustment that protects plants from the growth inhibition and/or injury that follow when environmental stresses are abruptly imposed.

Damage to photosystem II in symbiotic dinoflagellates: A determinant of coral bleaching
TL;DR: Temperature-dependent loss of PSII activity and concomitant decrease in D1 reaction center protein seen in symbionts collected from corals naturally bleached on the reef are confirmed, indicating that perturbation ofPSII protein turnover rates during photoinhibition at elevated temperatures underlies the physiological collapse of symbiont in corals susceptible to heat-induced bleaching.

TL;DR: Heat led to a sun-type adaptation response of the photosynthesis pigment apparatus for the Nagcarlang genotype, but not for Campbell-28, and thus an increase in chlorophyll a/b ratio and a decrease inchlorophyll/carotenoid ratio were shown in Nag carlang stressed plants.
Journal ArticleDOI
Electron transport is the functional limitation of photosynthesis in field-grown Pima cotton plants at high temperature
TL;DR: It is concluded that photosynthesis in field-grown Pima cotton leaves is functionally limited by photosynthetic electron transport and RuBP regeneration capacity, not Rubisco activity.

The relationship between the quantum yield of photosynthetic electron transport and quenching of chlorophyll fluorescence
TL;DR: In this article, the quantum yield of non-cyclic electron transport was found to be directly proportional to the product of the photochemical fluorescence quenching (qQ) and the efficiency of excitation capture by open Photosystem II (PS II) reaction centres (Fv/Fm).

Quenching of chlorophyll fluorescence and primary photochemistry in chloroplasts by dibromothymoquinone.
M. Kitajima,Warren L. Butler +1 more
TL;DR: FO and FV are the same type of fluorescence, both emanating from the bulk chlorophyll of Photosystem II, according to simple theory, which predicts that the ratio FV/FM should equal phipo.

Detection of rapid induction kinetics with a new type of high-frequency modulated chlorophyll fluorometer.
TL;DR: In this article, a modulation fluorometer is described which operates with 1 µsec light pulses from a light-emitting diode (LED) at 100 KHz and tolerates ratios of up to 1:107 between measuring light and actinic light.

Stress Tolerance of Photosystem II in Vivo Antagonistic Effects of Water, Heat, and Photoinhibition Stresses
TL;DR: The results demonstrate the existence of a marked antagonism between physicochemical stresses, with water stress enhancing the resistance of photosystem II to constraints (heat, strong light at high temperature) that are usually associated with drought in the field.
