Importance of mesophyll diffusion conductance in estimation of plant photosynthesis in the field [PDF]

Journal of Experimental Botany, 2009
Mesophyll diffusion conductance to CO(2) (g(m)) is an important leaf characteristic determining the drawdown of CO(2) from substomatal cavities (C(i)) to chloroplasts (C(C)). Finite g(m) results in modifications in the shape of the net assimilation (A) versus C(i) response curves, with the final outcome of reduced maximal carboxylase activity of ...

Effects of sex and soil water chemistry on leaf morphology and physiology of Myrica gale var. tomentosa.

PLoS ONE, 2022
Plants respond to environmental stressors, such as an oligotrophic environments, by altering the morphological and physiological functions of their leaves. Sex affects these functions because of the asymmetric cost of reproduction in dioecious plants. We

Stomatal, mesophyll and biochemical limitations to soil drought and rewatering in relation to intrinsic water-use efficiency in Manchurian ash and Mongolian oak

Photosynthetica, 2021
The balance between stomatal and mesophyll conductance has been reported to directly influence intrinsic water-use efficiency (WUEi), but it is unclear whether variations in stomatal and mesophyll limitations (lsc and lm, respectively) affect WUEi during

Response of the leaf photosynthetic rate to available nitrogen in erect panicle-type rice (Oryza sativa L.) cultivar, Shennong265

Plant Production Science, 2016
Increasing the yield of rice per unit area is important because of the demand from the growing human population in Asia. A group of varieties called erect panicle-type rice (EP) achieves very high yields under conditions of high nitrogen availability ...

Mesophyll conductance in gymnosperms

, 2020
Mesofülli juhtivuseks nimetatakse süsihappegaasi difundeerumise kiirust läbi lehe õhulõhedealusest ruumist taimerakkudes asuvate kloroplastideni. Fotosünteesi biokeemia ja õhulõhede juhtivuse kõrval on see tähtis fotosünteesi efektiivsust määrav etapp. Mesofülli juhtivus piirab fotosünteesi kiirust ning seega taimede kasvu. Seetõttu põhjustab mesofülli

PagPIP1;2 overexpression increases leaf CO2 conductance, photosynthesis, and biomass accumulation in poplar

Industrial Crops and Products
Forests produce wood biomass and remove atmospheric carbon dioxide (CO2) via photosynthesis. Mesophyll conductance (gm) is a major limiting factor in leaf photosynthesis.

Spatio-temporal decoupling of stomatal and mesophyll conductance induced by vein cutting in leaves of Helianthus annuus

Frontiers in Plant Science, 2013
Reduction of hydraulic conductance to the canopy has been shown to result in stomatal responses to limit transpiration. To test for similar responses to perturbations of the hydraulic network in leaves, we simultaneously measured leaf gas exchange with ...

The importance of mesophyll conductance in regulating forest ecosystem productivity during drought periods [PDF]

, 2010
Water availability is the most limiting factor to global plant productivity, yet photosynthetic responses to seasonal drought cycles are poorly understood, with conflicting reports on which limiting process is the most important during drought.

Role of mesophyll diffusion conductance in constraining potential photosynthetic productivity in the field [PDF]

, 2013
Limited mesophyll diffusion conductance to CO2 (gm) can significantly constrain plant photosynthesis, but the extent of gm-limitation is still imperfectly known.

Freezing stress induces changes in the morphophysiological of chickpea and wild mustard seedlings

Legume Science, 2023
Wild mustard is one of the common and troublesome winter weeds of chickpea fields and a great competitor to reduce the chickpea productivity. Plant species (chickpeas cv. Saral and wild mustard) were compared at freezing temperatures (+4 as a control, 0,
