An evaluation of the effects of exogenous ethephon, an ethylene releasing compound, on photosynthesis of mustard (Brassica juncea) cultivars that differ in photosynthetic capacity

BMC Plant Biology, 2004
Background The stimulatory effect of CO2 on ethylene evolution in plants is known, but the extent to which ethylene controls photosynthesis is not clear. Studies on the effects of ethylene on CO2 metabolism have shown conflicting results.

A dynamic hydro-mechanical and biochemical model of stomatal conductance for C4 photosynthesis [PDF]

, 2017
C4 plants are major grain (maize, sorghum), sugar (sugarcane) and biofuel (Miscanthus) producers, and contribute ~20% to global productivity. Plants lose water through stomatal pores in order to acquire CO2 (assimilation, A), and control their carbon ...

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, EarlyView.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...

Rethinking Guard Cell Metabolism [PDF]

, 2016
Stomata control gaseous fluxes between the internal leaf air spaces and the external atmosphere and, therefore, play a pivotal role in regulating CO 2 uptake for photosynthesis as well as water loss through transpiration.

Leaf photoprotection and water relations traits reveal novel axes of coordination and trade‐offs in leaf function

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants can express considerable plasticity in leaf functional traits, but that plasticity may be constrained by coordination and trade‐offs among multiple functions.

Light Intensity Dependence of CO₂ Assimilation Is More Related to Biochemical Capacity Rather than Diffusional Conductance

Plants
The response of CO2 assimilation rate (AN) to incident light intensity reflects the efficiency of light utilization. The light intensity dependence of AN varies widely among different plant species, yet the underlying mechanisms remain poorly understood.

Comparative Genomic Analysis of Rice with Contrasting Photosynthesis and Grain Production under Salt Stress. [PDF]

, 2019
Unfavourable environmental conditions, including soil salinity, lead to decreased rice (Oryza sativa L.) productivity, especially at the reproductive stage.

Effects of dopamine on reducing salt stress damage in pepper (Capsicum annuum L.) at morphological, physiological, biochemical, and molecular levels

Annals of Applied Biology, EarlyView.
Salt stress causes oxidative and osmotic stress, resulting in decreased nutrient uptake, plant growth, and photosynthetic rate. This study suggests that foliar application of dopamine can reduce salinity‐induced oxidative damage in pepper plants by altering antioxidant activity, biochemical, and molecular responses.

Photosynthetic response of an alpine plant, Rhododendron delavayi Franch, to water stress and recovery: the role of mesophyll conductance

Frontiers in Plant Science, 2015
Rhododendron delavayi Franch is an evergreen shrub or small tree with large scarlet flowers that makes it highly attractive as an ornamental species. The species is native to southwest China and southeast Asia, especially the Himalayan region, showing ...

On the use of leaf spectral indices to assess water status and photosynthetic limitations in Olea europaea L. during water-stress and recovery. [PDF]

PLoS ONE, 2014
Diffusional limitations to photosynthesis, relative water content (RWC), pigment concentrations and their association with reflectance indices were studied in olive (Olea europaea) saplings subjected to water-stress and re-watering. RWC decreased sharply
