Summary: The limits of stomatal conductance in plants are determined by the size and density of stomata. There is an inverse relationship between stomatal size and density in both fossil and living plants. However, the functional significance of this relationship is still unclear, and it may reflect geometric constraints rather than physiological control. Understanding the tradeoffs involved in stomatal size and density and their interaction with atmospheric CO2 levels is crucial for developing more productive and climate-resilient crops.

Summary: The atmospheric concentration of CO2 and O2 directly affects the rates of photosynthesis and photorespiration. CO2 availability has likely acted as a stronger selective pressure than O2 in plant evolution. Species evolved in high CO2:O2 environments have higher photosynthetic rates and diffusive conductance. Rising CO2 levels will enhance photosynthesis rates in species with low conductance to CO2.

Summary: Phosphorus deficiency negatively affects leaf growth and photosynthesis in wheat plants. Lower phosphorus concentration leads to a significant decrease in leaf photosynthetic rate and leaf area, with the decrease in leaf area occurring earlier. The maintenance thresholds of phosphorus concentration for high photosynthesis and leaf growth were identified. The decrease in leaf photosynthetic rate was mainly caused by changes in stomatal conductance and mesophyll conductance.

Summary: This study investigates how rhizomatous growth and vascular construction affect whole-plant hydraulic function in ferns. The results show that nodal regions in rhizomatous ferns act as chokepoints, reducing hydraulic integration between phytomers. However, these chokepoints also play a role in hydraulically localizing each phytomer, potentially decreasing embolism and pathogen spread. The study also suggests that shoot-borne roots and the prostrate habit of rhizomatous ferns decrease hydraulic and structural burdens.

Summary: This study estimated the increasing trend of evapotranspiration (ET) over Eurasia during 1982-2014 using a remote sensing-based water-carbon coupling model. The results showed that the increasing trend was mainly from vegetated regions in central and eastern Europe, India, and southeast China. Sensitivity experiments indicated that climate forcing and increased leaf area index (LAI) were the major drivers of the Eurasian ET trend.

Summary: Recent reports question the assumption of leaf gas exchange analysis that leaf air spaces are effectively saturated with water vapor. Spatial heterogeneities may contribute to the appearance of undersaturation in internal leaf air spaces. Further refinement of experimental approaches is needed to distinguish undersaturation from the effects of spatial variations in fluxes or conductances.

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: The transition from mafic to felsic upper continental crust (UCC) is significant for the evolution of Earth and its inhabitants. V isotope ratios (δV-51) can provide insights into this transition. The δV-51 values of glacial diamictites from Archean to Paleozoic show that the UCC was dominantly mafic around 3 Ga but became felsic after that time.

Summary: This study investigated the hydraulic vulnerability of grass species and found that they have high resistance to xylem embolism. Reductions in stomatal conductance and leaf hydraulic conductance occurred even under mild water stress. The results suggest that factors other than xylem embolism contribute to reductions in productivity of pasture grasses during drought.

Summary: Grassland biomass production is influenced by the timing and intensity of precipitation events. This study examined the effects of drought on biomass production, growth-related traits, and competitive effects in three pasture grasses. The severity and frequency of drought were found to be key factors in plant-plant interactions, and differences in traits and responses to drought were important in predicting competition. The shifts in competition interactions associated with drought and recovery are likely to have significant effects on grass-dominated plant communities.

Summary: In this study, the researchers investigated the drought response strategies of four common tree species and found variability in their physiological adaptations to drought. Species such as Ormosia pinnata and Dalbergia odorifera showed specific traits to reduce water loss, while Michelia macclurei exhibited the highest tolerance to drought due to earlier stomatal closure and lower turgor loss point. The findings highlight the importance of understanding species-specific responses to drought in managing forest ecosystems.

Summary: Leaf hydraulic traits play a crucial role in plant drought tolerance and responses to climate change. This study focused on perennial grass species in eastern Australia and investigated the trade-offs between drought tolerance and plant morphology. The results showed that taller and more productive grass species had less drought-tolerant leaves, characterized by low leaf dry matter content and less negative leaf hydraulic conductance. Stomatal closure and turgor loss occurred at more negative leaf water potential in species with greater tiller production. These findings contribute to our understanding of grass hydraulic traits and their responses to drought in Australia.

Summary: A common garden experiment using 57 accessions of Brachypodium distachyon from different Mediterranean locations showed a negative correlation between silicon accumulation and temperature variables, as well as precipitation seasonality. However, these relationships were only observed in low-silicon soils and not in silicon-supplemented soils. These findings suggest that geographical origin and prevailing climatic conditions may influence patterns of silicon accumulation in grasses.

Summary: This study focused on the physiological traits and productivity of three eggplant cultivars in a high-tech glasshouse. The results showed that the cultivar Tracey had higher leaf growth and number of flowers per node compared to the other two varieties. Despite having the lowest net CO2 assimilation, Tracey produced the highest yield and better water use efficiency in terms of agronomic performance. However, further research is needed to understand the varietal performance of greenhouse eggplants and establish benchmarks for large-scale sustainable production.

Summary: This study investigated the phenotypic plasticity of four tree species under different precipitation and nitrogen deposition conditions. The results showed that changing precipitation reduced photosynthetic rate in Castanopsis fissa, while high nitrogen deposition increased photosynthetic rate in Ormosia pinnata. The growth of Dalbergia odorifera might be affected by precipitation and nitrogen deposition. These findings have important implications for selecting tree species that can adapt to future climate change.
