Diurnal Changes in Maize Leaf Photosynthesis

Apparent photosynthesis of soybean plants as affected by changes in leaf water potential under field conditions

Leaf Phosphate Status, Photosynthesis and Carbon Partitioning in Sugar Beet: II. Diurnal Changes in Sugar Phosphates, Adenylates, and Nicotinamide Nucleotides.

Sugar Beets (Beta vulgaris L. cv F58-554H1) were cultured hydroponically in growth chambers. Leaf orthophosphate (Pi) levels were varied nutritionally. The effect of decreased leaf phosphate (low-P) status was determined on the diurnal changes in the pool sizes of leaf ribulose 1,5-bisphosphate (RuBP), 3-phosphoglycerate (PGA), triose phosphate, fructose 1,6-bisphosphate, fructose-6-phosphate, ...

Photosynthesis in Maize'

Significant differenoes in CO2 compensation concentration measured in the field among varieties of the species Zea mays L. are reported for the first time. CO2 compensation concentrations were signifioantly (P< 0.01) and negatively oorrelated with apparent photosynthesis at 300 pl C02/liter air. The Michaelis constant (as defined) for a leaf was significantly (P< 0.01) and positively correlated...

Proteomics analysis reveals a dynamic diurnal pattern of photosynthesis-related pathways in maize leaves

Plant leaves exhibit differentiated patterns of photosynthesis rates under diurnal light regulation. Maize leaves show a single-peak pattern without photoinhibition at midday when the light intensity is maximized. This mechanism contributes to highly efficient photosynthesis in maize leaves. To understand the molecular basis of this process, an isobaric tag for relative and absolute quantitatio...

Canopy photosynthesis, evapotranspiration, leaf nitrogen, and transcription profiles of maize in response to CO2 enrichment

The effects of CO2 enrichment on the growth and physiology of maize were investigated at the molecular, biochemical, leaf, and canopy levels. Maize plants were grown in sunlit soil–plant–atmosphere research (SPAR) chambers at ambient (370 lmol mol ) or elevated (750 lmol mol ) atmospheric carbon dioxide concentration (Ca) under wellwatered and fertilized conditions. Canopy gas exchange rates an...
