Decarboxylation mechanisms of C4 photosynthesis in Saccharum spp.: Increased PEPCK activity under water-limiting conditions
(2019-04-16)
Background: C4 plants have been classified into three subtypes based on the enzymes used to decarboxylate C4 acids in the bundle sheath cells (NADP-ME, NAD-ME and PEPCK pathways). Evidences indicate that, depending on ...
Gas exchange rates at different vapor pressure deficits and water relations of 'Pera' sweet orange plants with citrus variegated chlorosis (CVC)

Relationship between isoprene emission and photosynthesis in diatoms, and its implications for global marine isoprene estimates
(2017)
Global consensus estimates of marine isoprene emission (~ 1 TgC yr− 1) is significantly smaller than terrestrial isoprene emission (~ 500 TgC yr− 1), and the reasons are unclear. With the premise that isoprene emission is ...
Solar UVR-induced DNA damage and inhibition of photosynthesis in phytoplankton from Andean lakes of Argentina
(E. Schweizerbart'sche Verlagsbuchhandlung, 2004-10)
During January 1999, studies were carried out in temperate lakes of the Andean region of Argentina (41° S, 71° W) to determine the short-term effects of solar ultraviolet radiation (UVR, 280 – 400 nm) upon natural phytoplankton ...
Photosynthetic characteristics of charophytes from tropical iotic ecosystems
(2003-03-01)
Responses of photosynthetic rates, determined by oxygen evolution using the light and dark bottles technique, to different temperatures, irradiances, pH, and diurnal rhythm were analyzed under laboratory conditions in four ...
Photosynthetic response curve of grafted and non-grafted Japanese cucumber plants in relation to irradiance
(2019-01-01)
Photosynthesis is directly proportional to light and the stomatal aperture reduces with the decrease in irradiance. The increase in irradiance reduces the respiration and photorespiration, besides increasing CO2 fixation. ...
Photoinduced Quantum Tunneling Model Applied to an Organic Molecule
(2020-10-01)
The paper proposes a photoinduced quantum tunneling model of electron transfer through four quantum square wells potential to simulate the biological process of photosynthesis in bacteria. The problem is mathematically ...
Relationships of leaf net photosynthesis, stomatal conductance, and mesophyll conductance to primary metabolism: a multi-species meta-analysis approach
(American Society of Plant Biologist, 2016-05)
Plant metabolism drives plant development and plant-environment responses, and data readouts from this cellular level could provide insights in the underlying molecular processes. Existing studies have already related key ...
Effect of mitochondrial ascorbic acid synthesis on photosynthesis
(Elsevier France-editions Scientifiques Medicales Elsevier, 2016-07)
Ascorbic acid (AA) is synthesized in plant mitochondria through the oxidation of L-galactono-1,4-lactone (L-GalL) and then distributed to different cell compartments. AA-deficient Arabidopsis thaliana mutants (vtc2) and ...
