Summary: Mesophyll conductance plays a crucial role in carbon transport and fixation during photosynthesis, especially under CO2 enrichment conditions. Overexpression of plasma membrane aquaporin SlPIP1;2 significantly enhances CO2 membrane permeability, improving mesophyll conductance and photosynthesis rate, leading to increased crop productivity and water use efficiency.

Summary: The study investigated the photosynthetic acclimation of a japonica rice cultivar under elevated CO2 levels, finding that the decrease in photosynthetic rate was mainly limited by mesophyll conductance (g(m)). The results underscore the significant role of g(m) in photosynthetic acclimation under elevated CO2 conditions in rice.

Summary: In this study, the effects of nitrogen supplies on rice leaf anatomy and leaf chemical composition were investigated using four rice genotypes. The results showed that nitrogen supplies had a significant impact on leaf nitrogen content and net photosynthetic rate, but no effect on stomatal conductance, mesophyll conductance, and photosynthetic nitrogen use efficiency. Nitrogen supplies also had no significant effect on leaf mass per area, cell wall thickness, and most of the leaf chemical components.

Summary: The study analyzed the influence of cotton domestication on leaf anatomy and mesophyll conductance. It found that domesticated cotton genotypes had higher photosynthetic rates but similar mesophyll conductance to wild genotypes, due to compensating changes in cell wall and cytoplasmic conductances.

Summary: This study investigates the role of the plasma membrane aquaporin protein SlPIP1;2 in moderating plant water stress and photosynthetic depression under high vapor pressure deficit (VPD) conditions. The results show that SlPIP1;2 enhances plant water uptake and photosynthetic efficiency, reducing the plant's stress response under high VPD conditions.

Summary: We propose a reliable method to estimate the CO2 concentration at the surface of photosynthetic mesophyll cells (c(w)) using independent adaxial and abaxial gas exchange measurements and accounting for mesophyll airspace resistances. Our experiments using model plants confirm that c(w) is lower than adaxial and abaxial estimated intercellular CO2 concentrations (c(i)), with differences usually larger than 10 mu mol mol(-1). Accounting for c(w) improves the information that can be extracted from gas exchange experiments, providing a more detailed description of the CO2 and water vapor gradients within the leaf.

Summary: We found that drought stress delays the initiation of photosynthesis and exacerbates the loss of carbon gain under fluctuating light in tomato seedlings. Additionally, drought stress aggravates the over-reduction of photosystem I and suppresses the photoprotection of photosystem I. However, drought stress also enhances relative cyclic electron flow, which partially compensates for restricted CO2 fixation and promotes the photoprotection of photosystem I.

Summary: Deschampsia antarctica is a native vascular plant in Antarctica, and the availability of nutrients in the soil affects its photosynthetic and stress tolerance mechanisms. Plants growing on low-nutrient availability soils have more limiting photosynthetic and stress tolerance performances, while plants in nutrient-rich soils show vigorous growth without appreciable levels of stress.

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 reveals that the decrease in leaf N content delays the induction speeds of net CO2 assimilation, stomatal conductance, and mesophyll conductance upon transition from low to high light in tomato seedlings. The photosynthetic induction kinetics are mainly affected by the induction response of mesophyll conductance rather than stomatal conductance.

Summary: Leaf growth depends on photosynthesis and hydraulics for carbohydrates and expansion power. Under potassium deficiency, leaf area, photosynthesis, and hydraulics are affected by changes in leaf structure. This study observed the leaf hydraulic conductance and photosynthetic rate of Brassica napus during leaf growth under different levels of potassium supply. The results showed that potassium deficiency decreased leaf hydraulic conductance and photosynthetic rate. It also led to an increase in mesophyll cell investment and a decrease in the volume fraction of intercellular air-space, resulting in reduced leaf expansion rate.

Summary: This study discovered unique single-celled salt glands in Oryza coarctata, the only salt tolerant species in the genus Oryza, which is different from the bicellular glands found in other salt excreting grasses. The mechanisms of salt tolerance and excretion were compared in three grass species, and it was found that they have similar mechanisms for providing tolerance and excreting Na+ and K+.

Summary: Measurements and models of Delta O-18(LW) were compared to evaluate the influence of leaf anatomy and cell wall properties on leaf water transport. The results showed that cell wall composition and stomatal density have an impact on Delta O-18(LW) and stable isotopes can help develop a detailed water transport model.

Summary: Changes in hydroxycinnamic acid content can decrease cell wall thickness, increase mesophyll conductance and photosynthesis in C-3 cereals. However, increases in stomatal conductance negate the increased photosynthesis, resulting in no change in intrinsic water use efficiency (WUE). Alteration of hydroxycinnamic acid content can also improve canopy-level WUE and aboveground biomass in rice plants under low water levels.

Summary: The study focuses on the function of formins in cytokinesis, suggesting their roles in promoting microtubule polymerization, nucleating F-actin at the cell plate, retaining dynamin-related proteins at the cell plate, and remodeling the cell plate membrane. The use of SMIFH2 has helped reveal the impact of formins on these processes.
