Herbivore induction of jasmonic acid and chemical defences reduce photosynthesis in Nicotiana attenuata
(Oxford University Press, 2013-01)
Herbivory initiates a shift in plant metabolism from growth to defence that may reduce fitness in the absence of further herbivory. However, the defence-induced changes in carbon assimilation that precede this reallocation ...
Photosynthesis, Chlorophylls, and SPAD Readings in Coffee Leaves in Relation to Nitrogen Supply
(TAYLOR & FRANCIS INC, 2009)
The export of nitrogen (N) from senescent plant parts is important for the efficient use of this macronutrient. The objective of this study was to establish correlations among the photosynthetic pigment content, total N, ...
Assessment of the potential toxicity of glyphosate-based herbicides on the photosynthesis of Nitella microcarpa var. wrightii (Charophyceae)
Although macroalgae are considered one of the most important primary producers in streams, to our knowledge there has been no research on the effects of herbicides on these organisms. Such studies are crucial for improving ...
An Artificial Photosynthesis System Based on Ti/TiO2 Coated with Cu(II) Aspirinate Complex for CO2 Reduction to Methanol
A novel copper(II) aspirinate complex easily deposited onto nanotubes of Ti/TiO2 was successfully employed in the conversion of CO2 to methanol through the use of UV-Vis irradiation coupled to a bias potential of −0.35 V ...
Relationship between isoprene emission and photosynthesis in diatoms, and its implications for global marine isoprene estimates
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 ...
Elevated CO(2) increases photosynthesis, biomass and productivity, and modifies gene expression in sugarcane
Because of the economical relevance of sugarcane and its high potential as a source of biofuel, it is important to understand how this crop will respond to the foreseen increase in atmospheric [CO(2)]. The effects of ...
Gas exchange rates at different vapor pressure deficits and water relations of 'Pera' sweet orange plants with citrus variegated chlorosis (CVC)
(Elsevier Science BvAmsterdamHolanda, 2003)
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 ...
The maize coleoptiles do not perform typical C4 photosynthesis: investigation with special reference to anatomy, photosynthetic property, and gene expression
(Japanese Society of Plant Morphology, 2012-12)
Maize (Zea mays L.) is one of the most representative C4 plants. However, several reports have suggested the occurrence of C3 photosynthesis in this C4 plant. We examined the photosynthetic characteristics of the coleoptiles, ...
