Trehalose alleviates salt tolerance by improving photosynthetic performance and maintaining mineral ion homeostasis in tomato plants by Yan Yang, Jianming Xie, Jing Li, Jing Zhang, Xiaodan Zhang, Yandong Yao, Cheng Wang, Tianhang Niu, Emily Patience Bakpa

“…However, exogenous application of Tre significantly increased photosynthetic efficiency, increased the activity of Calvin cycle enzymes [ribulose diphosphate carboxylase/oxygenase (Rubisco), fructose-1,6-bisphosphate aldolase (FBA), fructose-1, 6-bisphosphatase (FBPase), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and transketolase (TK)], up-regulated the expression of genes encoding enzymes, induced stomatal opening, and alleviated salt-induced damage to the chloroplast membrane and structure. In the saline environment, photosynthetic electron transport was restricted, resulting the J-I-P phase to decrease. …”

β-Cyclocitral Does Not Contribute to Singlet Oxygen-Signalling in Algae, but May Down-Regulate Chlorophyll Synthesis by Thomas Roach, Theresa Baur, Ilse Kranner

“…Light stress signalling in algae and plants is partially orchestrated by singlet oxygen (¹O₂), a reactive oxygen species (ROS) that causes significant damage within the chloroplast, such as lipid peroxidation. In the vicinity of the photosystem II reaction centre, a major source of ¹O₂, are two β-carotene molecules that quench ¹O₂ to ground-state oxygen. …”
