Summary: Cotton domestication has increased the number and size of abaxial stomata, resulting in higher maximum stomatal conductance and lower water use efficiency. This study found that domesticated cotton genotypes have lower water use efficiency compared to wild genotypes. The increase in stomatal conductance after domestication is due to an increase in stomata, rather than enlarged stomata. However, there is a negative relationship between stomatal size and carbon isotope discrimination, especially on the abaxial leaf surface, indicating that bigger stomata lead to increased water loss. This study suggests that future breeding efforts could improve water use efficiency and drought tolerance by decreasing the size of abaxial stomata to increase stomatal response and reduce unnecessary water loss.

Summary: The study explored the impact of reduced irrigation and biochar addition on stomatal morphology and gas exchange of tobacco plants. It was found that reduced irrigation, especially alternate partial root-zone drying irrigation, led to lower stomatal conductance and increased water-use efficiency, with biochar having little effect. In addition, stomatal size decreased while density increased under reduced irrigation, particularly with biochar addition.

Summary: The use of stable isotopes to understand plant physiological processes has become common in ecology. However, there is currently no standardized tool to calculate isotope-derived plant physiological indices. In response, we developed isocalcR, an R package that provides functions and reference data to simplify the use of stable isotope data in plant tissues.

Summary: The limitations and utility of three measures of water use characteristics were evaluated. The measure partial differential E/ partial differential A$$ \partial E/\partial A $$ was found to provide an integrated representation of carbon gain relative to water use under varying environmental conditions. This mechanistic means of predicting water use characteristics adds depth to understanding how plants balance water expenditure against carbon gain.

Summary: Increases in terrestrial water-use efficiency (WUE) have been reported, but longer-term gains in WUE are uncertain due to difficulties in accounting for structural and physiological acclimation. This study used C-13 signatures of plant organic matter to estimate WUE and found that the gains in WUE during the 20th century were smaller than previously estimated. Plant structure and physiology were found to significantly influence WUE. Therefore, previous estimates of increased forest WUE may have been overestimated, and projections of future climate forcing via CO2 fertilization may need to be adjusted accordingly.

Summary: Carbon isotope composition (delta C-13) is widely used to estimate the intrinsic water-use efficiency (iWUE) of plants, providing valuable insights into the functional response of plants to climate change. However, the current literature lacks comprehensive review papers on the theoretical basis, assumptions, and uncertainty of C-13-based iWUE models. This study presents different models and discusses their limitations, emphasizing the importance of understanding mesophyll conductance and post-photosynthetic fractionation for improving the accuracy of iWUE estimation.

Summary: Carbon isotope discrimination (Delta) is widely used to infer intrinsic water-use efficiency (iWUE) of C-3 plants, but the effect of mesophyll conductance (g(m)) on Delta-based predictions of iWUE has been generally neglected. This study derived a mathematical expression of iWUE as a function of Delta that includes g(m) (iWUE(mes)) and found that the inclusion of the g(sc) : g(m) ratio greatly improved estimates of iWUE across various C-3 vegetation types.

Summary: The study investigated the effects of water stress under low phosphorus supply on P-acquisition by chickpea and identified a genotype with faster relative growth and P-acquisition rates. ICC 2884 genotype showed faster P-acquisition rate with greater specific root length, smaller mean root diameter, and increased rhizosheath carboxylates in response to water stress. It also maintained similar physiological P-use efficiency under water stress, making it recommended for chickpea breeding in low-P and terminal drought environments.

Summary: This study aimed to investigate the effects of different drought intensities and timings on physiological parameters of hemp and determine the possibility of selecting drought-tolerant cultivars. The results showed that moderate water stress had the least impact on physiological parameters, while intense water stresses significantly reduced photosynthesis and stomatal conductance. There was physiological variation in the response to drought between cultivars, suggesting the presence of genotypic variation in these traits that contribute to drought tolerance.

Summary: Stomatal morphology plays an important role in regulating leaf gas exchange and photosynthetic efficiency under fluctuating light conditions. Smaller and denser stomata lead to faster stomatal response to light fluctuations but lower intrinsic water use efficiency. Stomatal morphology has less impact on stomatal conductance, and there is minimal correlation between steady-state and non-steady-state stomatal conductance among different genotypes. These findings highlight the significance of stomatal morphology in optimizing photosynthetic efficiency and plant growth under fluctuating light.

Summary: The impacts of plastic particles, especially in agro-ecosystem, are being extensively studied. In a simulation experiment, elevated atmospheric CO2 concentration increased nanoplastics concentration in NPs-treated roots. Furthermore, elevated CO2 concentration decreased H2O2 concentrations in NPs-treated leaves and roots by intervening antioxidant enzymes. In NPs-treated plants, elevated CO2 concentration increased P-n, C-i, and carotenoid concentration, while decreased g(s) and T-r. These findings provide insights into the eco-physiological response of barley plants to NPs under future agricultural sustainability.

Summary: Biochar amendment improves crop growth and nutrient utilization in the soil, specifically in terms of root morphology and nutrient uptake in maize plants. Although biochar has a negative effect on soil phosphorus, it positively affects nitrogen, potassium, and calcium. While biochar lowers nutrient concentrations in shoot tissues, it increases total nutrient uptake and biomass. The use of limited root irrigation methods, such as alternate partial root-zone drying, enhances root-to-shoot ratio.

Summary: This study investigated the effects of inoculating plant growth promoting rhizobacteria (PGPR) and soil water deficits on the growth and physiology of tomato plants. The results showed that soil water deficits significantly decreased leaf gas exchange, growth, and water use efficiency (WUE), while reduced irrigation regimes significantly lowered dry matter and plant water use. However, PGPR inoculation had little effect on WUE. The study also found synergistic effects of PGPR and deficit irrigation on leaf gas exchange, leaf abscisic acid content, and stomatal density.

Summary: Three genotypes of wheat were tested in a drought experiment with different CO2 concentrations. Canopy size had a greater impact on water use and drying rate than stomatal density and conductance. The largest genotype showed the lowest decrease in grain yield and there was a close correlation between F-v/F-m and percentage of yield loss. F-v/F-m can effectively predict yield loss after severe drought at anthesis.

Summary: This study investigated the mode of action of a commercial Bacillus paralicheniformis FMCH001 in promoting soybean growth under well-watered and drought conditions. The results showed that FMCH001 colonizes the roots, improves root growth, and enhances nutrient absorption from the soil. Under drought stress, FMCH001 significantly improves photosynthesis rate, stomatal conductance, and transpiration rate, resulting in increased water use efficiency. Inoculated soybean plants use 22.94% less water compared to the control, without compromising biomass production.

Summary: The long-term effect of elevated atmospheric CO2 concentration (e[CO2]) on wheat over multiple generations was studied. The results showed that e[CO2] increased shoot biomass and grain yield over three generations, with a greater enhancement in the third generation. However, e[CO2] reduced plant N concentration and inhibited C translocation to grain, resulting in lower grain quality. The negative impacts of e[CO2] were exacerbated in the third generation, and micronutrient concentrations in grain were significantly lowered. The cultivar 325Jimai exhibited the greatest increase in shoot biomass and grain yield, suggesting its potential for future breeding strategies.

Summary: This study found that abscisic acid (ABA) plays a significant role in mediating the response of stomata to elevated CO2 and drought. Elevated CO2 promotes ABA accumulation and regulates the expression of ABA biosynthetic and metabolic genes, enhancing drought tolerance in plants. In the ABA mutant flacca, ethylene functions as a compensatory role in inducing stomatal closure during soil drying.
