Floating transition unlocks a photosynthesis-centered physiological advantage enabling dominance of

Environmental and Experimental Botany
In Yellow Sea green tides (YSGTs), the macroalga Ulva prolifera exhibits negligible competitive superiority in the attached growth stage but rapidly outcompetes co-occurring Blidingia sp. after shifting to floating lifestyles.

The Role of Light and Oxygen in the Action of the Photosynthetic Inhibitor Herbicide Monuron

Zeitschrift für Naturforschung C, 1979
Abstract Monuron treatment of detached flax cotyledons caused a rapid inhibition of CO2 fixation in darkness and light. Chlorophyll breakdown was promoted by increased light intensity. Ethane generation, an indicator of membrane damage, increased as the chlorophyll level decreased.

Fertilizer type influences tomato yield and soil N2O emissions

Plant, Soil and Environment, 2017
Improvements in crop management for a more sustainable agriculture are fundamental to reduce environmental impacts of cropland and to mitigate effects on global climate change. In this study three fertilization types - ammonium nitrate (control); mineral

The measurement of seagrass photosynthesis using pulse amplitude modulated (PAM) fluorometry and its practical applications, specifically in regard to transplantation [PDF]

, 2006
Photosynthetic activity of three seagrass species, Posidonia sinuosa Cambridge et Kuo, Posidonia australis Hook. f. and Halophila ovalis (R. Br.) Hook., growing in Cockburn Sound, Western Australia, was assessed using an underwater pulse amplitude ...

cDNA cloning, expression levels and gene mapping of photosynthetic and non-photosynthetic ferredoxin genes in sunflower (Helianthus annuus L.)

, 2009
Fatty acid desaturation in plastids and chloroplasts depends on the electron-donor activity of ferredoxins. Using degenerate oligonucleotides designed from known photosynthetic and heterotrophic plant ferredoxin sequences, two full-length ferredoxin ...

Optimizing RuBP regeneration to increase photosynthetic capacity [PDF]

, 2014
The regeneration of RuBP is a major factor limiting photosynthesis at sub-saturating light levels. Optimizing this process by overexpressing the enzymes sedoheptulose-1,7-bisphosphatase (SBPase) and fructose-1,6-bisphosphate aldolase (FBP aldolase) is ...

Primary photosynthetic processes: from supercomplex to leaf [PDF]

, 2009
This thesis describes fluorescence spectroscopy experiments on photosynthetic complexes that cover the primary photosynthetic processes, from the absorption of light by photosynthetic pigments to a charge separation (CS) in the reaction center (RC ...

Natural Rubrolides and Their Synthetic Congeners as Inhibitors of the Photosynthetic Electron Transport Chain

Journal of Natural Products
Rubrolides are a family of naturally occurring 5-benzylidenebutenolides, which generally contain brominated phenol groups, and nearly half of them also present a chlorine attached to the butenolide core. Seven natural rubrolides were previously synthesized.

Nitric Oxide Functions as a Key Mediator in Brassinosteroid-Enhanced Alkaline Tolerance in Cucumber

Plants
This study investigated how exogenous 2,4-epibrassinolide (EBR) and nitric oxide (NO) enhance the tolerance of cucumber (Cucumis sativus L.) seedlings to NaHCO3-induced alkaline stress under hydroponic conditions.

Salt stimulates carbon fixation in the halophyte Nitraria sibirica to enhance growth

Forestry Research
Soil salinity significantly inhibits plant productivity by adversely affecting photosynthesis and growth. Nitraria sibirica, a typical halophyte, exhibits strong salt tolerance.
