Alpha Carbonic Anhydrase 5 Mediates Stimulation of ATP Synthesis by Bicarbonate in Isolated Arabidopsis Thylakoids

Frontiers in Plant Science, 2021
We studied bicarbonate-induced stimulation of photophosphorylation in thylakoids isolated from leaves of Arabidopsis thaliana plants. This stimulation was not observed in thylakoids of wild-type in the presence of mafenide, a soluble carbonic anhydrase ...

Light's interaction with pigments in chloroplasts: The murburn perspective

Journal of Photochemistry and Photobiology, 2021
The prevailing understanding on the light reaction of oxygenic photosynthesis (photolytic photophosphorylation & NADPH synthesis) considers the vast majority of the diverse pigments, chlorophyll binding proteins (CBPs) and light harvesting complexes (

INHIBITION OF SPINACH CHLOROPLAST PHOTOPHOSPHORYLATION AND ELECTRON TRANSPORT BY SELECTED NATURAL PRODUCTS [PDF]

Journal of Plant Protection and Pathology, 2006
The effects of the biflavonoid crassifolin (1), the flavonoid tephrobotin, the Annnonaceous acetogenins squamocin (3), and buliatacin (4) were investigated on different photosynthetic activities in isolated spinach chloroplasts.

Protective effect of bone marrow mesenchymal stem cell-derived exosomes against the reproductive toxicity of cyclophosphamide is associated with the p38MAPK/ERK and AKT signaling pathways

Asian Journal of Andrology, 2021
Spermatogenic dysfunction caused by cyclophosphamide (CP) chemotherapy has seriously influenced the life quality of patients. Unfortunately, treatments for CP-induced testicular spermatogenic dysfunction are limited, and the molecular mechanisms are not ...

Inhibition of Photophosphorylation by Kaempferol [PDF]

Plant Physiology, 1974
Kaempferol, a naturally occurring flavonol, inhibited coupled electron transport and both cyclic and noncyclic photophosphorylation in isolated pea (Pisum sativum) chloroplasts. Over a concentration range which gave marked inhibition of ATP synthesis, there was no effect on basal or uncoupled electron flow or light-induced proton accumulation by ...

Different responses of photosystem and antioxidant defense system to three environmental stresses in wheat seedlings

Photosynthetica, 2020
To investigate the adaptive mechanism of wheat under high light, osmotic stress, and salt stress, redox regulation, and photosynthesis were compared. Under high light, the activities of antioxidant enzymes, except for catalase, significantly increased ...

Gene Expression Patterns during Light and Dark Infection of Prochlorococcus by Cyanophage. [PDF]

PLoS ONE, 2016
Cyanophage infecting the marine cyanobacteria Prochlorococcus and Synechococcus require light and host photosystem activity for optimal reproduction. Many cyanophages encode multiple photosynthetic electron transport (PET) proteins, which are presumed to
