Summary: The study found that leaf economics and hydraulic traits are coupled in plants in hyper-arid regions, with factors such as mean annual precipitation, soil salt, and soil nutrients influencing these traits. This coupling provides an economical and efficient strategy for plants to adapt to harsh environments.

Summary: This study suggests a strong correlation between stomatal and leaf structures, and highlights the importance of mesophyll cell size in determining the coordination between stomatal size and mesophyll porosity. The findings also indicate a highly correlated development of stomata and mesophyll cells among different crop species.

Summary: This study examined the coordination between genome size, leaf cell sizes, cell packing densities, and leaf size in 13 mangrove species across four sites in China. The results showed that mangroves have small genome sizes and large cell sizes, which are influenced by climate conditions. The study also found unique relationships between guard cell size, epidermal cell size, and vein and stomata densities in mangroves compared to other angiosperms. These findings suggest the unique adaptations of mangroves to their stressful environments.

Summary: The increasing evaporative demand due to climate change will significantly affect the balance of carbon assimilation and water losses of plants worldwide. The development of crop varieties with improved water-use efficiency (WUE) will be critical for adapting agricultural strategies under predicted future climates. This review aims to summarize the most important leaf morpho-physiological constraints of WUE in C-3 plants and identify gaps in knowledge.

Summary: Leaf optical properties play a key role in interpreting remote sensing data on vegetation canopy structure and functions. By studying the seasonal patterns of leaf optical properties in different tree species, we can better understand the growth and development of vegetation. The reflectance and transmittance spectra of leaves exhibit distinct seasonal changes.

Summary: Under future climate change with elevated CO2 concentration and more frequent drought events, the positive acclimation responses of Chinese pear plantations to elevated [CO2] in terms of leaf photosynthesis are dampened by modifying stomatal morphology and distribution, leaf anatomy, and Rubisco gene expression. Therefore, incorporating drought limitations into current coupled climate-carbon models is necessary to avoid overestimation of the positive responses of Chinese pear plantations to elevated [CO2] and to accurately predict forest carbon sequestration.

Summary: Stomata in grasses consist of guard cells and subsidiary cells, with the latter playing a supportive role in regulating the opening and closing of stomatal pores. The study found that the distinctive geometry of grass stomata, featuring dumbbell-shaped guard cells, contributes to improved stomatal performance. In addition, a relatively thick guard cell rod region is necessary for enhancing pore opening.

Summary: By studying about 70 species of ferns, it was found that newly diverged ferns have thicker mesophyll, larger chloroplast surface area, thicker cell walls, and greater light absorptance. Although there was no significant difference in photosynthetic capacity on a leaf-area basis among newly diverged ferns, when measured on a mesophyll-thickness basis, different photosynthetic capacities were observed. Newly diverged species with thicker mesophyll had lower maximum photosynthesis rate and smaller chloroplast surface area. This suggests a strong link between light capture, mesophyll anatomy, and photosynthesis rate in fern species.

Summary: The stomatal responses to light intensity and CO2 concentration were found to differ between CAM and C-3 species, with CAM stomata showing unique behaviors in response to darkness and C-3 signals. Guard cell metabolism and mesophyll signals were identified as key factors influencing stomatal responses in both CAM and C-3 plants.

Summary: The study found that plants grown under different VPD conditions exhibited different physiological and anatomical traits. Plants grown under high VPD conditions showed reduced gas exchange parameters such as stomatal density and vein density, leading to decreased photosynthesis and stomatal conductance.

Summary: Leaf anatomy plays a crucial role in determining photosynthesis performance. In this study, two rice recombinant inbred lines, H138 and H217, showed higher net CO2 assimilation compared to their parent Sasanishiki, mainly due to improved leaf anatomy. The improvement in leaf anatomy was associated with increased mesophyll cell number and area, higher chlorophyll content, and increased expression of genes involved in light-harvesting. Furthermore, higher stomatal and mesophyll conductance in H138 and H217 contributed to improved leaf photosynthesis.

Summary: This study found that narrow leaves in soybean are thicker and have a higher proportion of spongy mesophyll, while the proportions of palisade and paraveinal mesophyll are lower. In addition, narrow and thicker leaves have higher photosynthesis and stomata conductance per unit area, along with greater leaf hydraulic conductance. Therefore, selecting for narrow leaves can improve photosynthetic performance and potentially increase soybean yield.
