Is chloroplast size optimal for photosynthetic efficiency?

open access: yesNew Phytologist, 2023
Improving photosynthetic efficiency has recently emerged as a promising way to increase crop production in a sustainable manner. While chloroplast size may affect photosynthetic efficiency in several ways, we aimed to explore whether chloroplast size ...

Warming reduces both photosynthetic nutrient use efficiency and water use efficiency in Mediterranean shrubsWarming reduces nutrient use efficiency [PDF]

open access: yesEnvironmental and Experimental Botany, 2023
[EN] The ratio between net photosynthetic rates and the foliar contents of essential plant macronutrients (N, P, K) is termed photosynthetic nutrient use efficiency (PNutUE).

Improving Photosynthetic Efficiency for Greater Yield

Annual Review of Plant Biology, 2010
Increasing the yield potential of the major food grain crops has contributed very significantly to a rising food supply over the past 50 years, which has until recently more than kept pace with rising global demand. Whereas improved photosynthetic efficiency has played only a minor role in the remarkable increases in productivity achieved in the last ...

EFFECTS OF ROOTSTOCK ON PEAR PHOTOSYNTHETIC EFFICIENCY

Acta Horticulturae, 2008
The effect of rootstock on scion photosynthesis can be quite marked. Reduced hydraulic conductivity at the graft union can negatively affect stomata conductance, which in turn may diminish gas exchanges and photosynthesis. Under high light intensities this condition can worsen, as a proportionally smaller fraction of intercepted photons can be utilized

An efficient mutational method for photosynthetic bacteria

Microbiology, 2006
The pigment and auxotrophic mutants of Rhodobacter sphaeroides Y6 were obtained by treatment with ethyl methanesulfonate (EMS) followed by lithium chloride (LiCI). Treatment with 0.081 M EPS and subsequent treatment with 0.071 M LiCI resulted in 12% higher frequency of pigment mutations than application of 0.081 M EMS alone; the frequency of ...

Stomata conductance as a goalkeeper for increased photosynthetic efficiency

Current Opinion in Plant Biology, 2022
100-120 words. References should not be included. Abbreviations should be avoided as far as possible. Low stomatal conductance (gs) poses a major constraint for improving photosynthetic efficiency for greater yield. Options at the molecular, leaf, canopy, and even the whole plant scales can be developed to enhance gs for greater light and water use ...

Photosynthetic and respiratory efficiency

1993
The growth rate of a plant depends on many environmental and endogenous factors,but can ultimately be defined in terms of carbon by the balance between photosynthetic CO20 assimilation and the respiratory costs, and also by a carbon partitioning factor, as modelled by Masle et al. (1990).
