Summary: Water availability has a significant impact on the morphological and physiological characteristics of maize as well as the environmental cost. Climate change has led to water stress even in previously well-supplied areas. However, farmers can still maintain or improve crop yield by effectively managing water resources in limited supply.

Summary: This study found that modifying the spectral environment with LED lighting can alter growth patterns and morphology in basil plants, affecting physiological performance and photosynthetic pigments. Different spectral color ratios significantly affect plant growth and physiological performance, with a 4:1:1 ratio proving to be the most effective for enhancing basil plant growth.

Summary: This study found that under high temperature conditions, the emission of leaf monoterpenes significantly increased in the INRA809 grape variety, while there was no significant change in the SMA130 variety. Additionally, when leaf temperature exceeded 30 degrees Celsius, INRA809 maintained higher photosynthetic rates and stomatal conductance values. This suggests that monoterpenes emission plays a significant role in heat tolerance of grapes under high temperatures.

Summary: Chlorophyll fluorescence can be used as a proxy for photosynthesis in boreal forests. This study measured the spectral chlorophyll fluorescence in leaves of three dominant evergreen species in the boreal ecosystem and analyzed the correlations with other traits to understand the spatial and temporal variation in chlorophyll fluorescence. The findings suggest that the diversity of species and light environments within an ecosystem generate baseline variation in leaf spectral chlorophyll fluorescence and contrasting seasonal photosynthetic acclimation patterns.

Summary: The study investigated the effects of different NaCl concentrations on the photosynthesis of maize and sorghum, revealing stronger impacts in maize compared to sorghum at certain NaCl concentrations. The changes in primary PSII photochemistry influenced the electron transport rate and photosynthetic rate, with maize showing stronger effects. Additionally, sorghum exhibited better salt tolerance at higher NaCl concentrations, associated with structural alterations in photosynthetic membranes and stimulation of cyclic electron flow around PSI.

Summary: This study classified tomato genotypes based on their response to high temperature using HCA and identified key physiological and yield traits using PCA. The results showed that traits such as photosynthesis, chlorophyll stability, and relative water content were important indicators of high temperature tolerance in tomato. PCA and HCA can be used as efficient screening methods for assessing the magnitude of high temperature tolerance in a large group of genotypes.

Summary: Anthropogenic land degradation and climate change-induced weather shocks pose a threat to rural livelihoods in developing economies. The Sustainable Land Management Project in Ethiopia has shown positive impacts in restoring land productivity and increasing resilience to weather shocks. Remote sensing technologies can be used to assess the effectiveness of ecosystem restoration programs.

Summary: The effects of CO2, temperature, and nitrogen supply on photosynthesis, root growth, and nitrogen allocation in strawberries were investigated. Elevated CO2 reduced photosynthetic rates and nitrogen concentration in leaves, accelerated leaf senescence, and increased root growth and nitrogen use efficiency. However, when nitrogen was supplied together with elevated CO2, root nitrogen concentration decreased but total root dry weight increased.

Summary: This study compared the growth of grafted and non-grafted greenhouse-grown cut rose flowers and found that grafting can improve the photosynthesis rate, transpiration rate, and stomatal conductance, thereby increasing yield. Grafting also improved root activity and resulted in morphological changes such as increased flower size and number of petals.

Summary: The maize genotype DKC7221 is more heat tolerant due to higher photosynthetic activity, while genotype P3167 is sensitive to high temperature with inhibited photosynthetic electron transport reactions. The study revealed that DKC7221 maintained photosynthetic efficiency under heat stress, while P3167 suffered oxidative stress and photooxidative injuries due to impaired photosynthetic efficiency.

Summary: The ZjNOL gene in the warm-season turfgrass Zoysia japonica was found to be highly expressed in senescent leaves. ZjNOL accelerates leaf senescence by promoting the accumulation of abscisic acid and carbohydrates, as well as causing excessive accumulation of reactive oxygen species and oxidative stress. Additionally, ZjNOL inhibits photosynthetic efficiency by damaging the oxygen-evolving complex. These findings highlight the important role of ZjNOL in chlorophyll degradation and senescence, making it a valuable candidate gene for genome editing to enhance the green period and photosynthesis efficiency of Z. japonica germplasm.

Summary: The temporal and spatial heterogeneity of chlorophyll content and fluorescence in rice canopy leaves under different Cd stress concentrations was explored in this study. The responses of relative chlorophyll content (SPAD) and chlorophyll fluorescence (ChlF) parameters to Cd stress in different growth stages were analyzed. It was found that lower leaves had higher SPAD values in the tillering stage, while upper leaves had higher SPAD values in the heading and filling stages. Certain ChlF parameters were more sensitive to Cd stress than others.
