Summary: This study assessed the impact of N supply on leaf anatomical, biochemical, and photosynthetic features in tobacco, revealing that high N treatment led to enhanced photosynthesis due to increased CO2 diffusion conductance and photosynthetic biochemical capacity. The increase in gm in leaves treated with high N was related to changes in leaf anatomy, but the rapid response to N top-dressing could not be fully explained by leaf anatomical modifications.

Summary: Creating a 3D 'virtual leaf' using microscopy datasets allows for a better understanding of carbon and water transport within leaves. By combining volume microscopy, modelling and experimental data, the 'virtual leaf' can provide insights into leaf anatomy and function. This tool can be used computationally to increase our understanding of processes like photosynthesis, respiration, and water transport.

Summary: The decline in mesophyll conductance (g(m)) is crucial in limiting photosynthesis in plants exposed to elevated ozone (O-3) levels. Leaf anatomical traits have been known to impact g(m), but the potential effects of O-3-induced changes in leaf anatomy on g(m) are still unclear. In this study, two poplar clones were exposed to elevated O-3 levels. The impacts of O-3 on photosynthetic capacity and anatomical characteristics were assessed to investigate the leaf anatomical properties that potentially affect g(m). Additionally, a global meta-analysis was conducted to explore the general response patterns of g(m) and leaf anatomy to O-3 exposure. The findings suggest that O-3-induced reduction in g(m) is critical in limiting leaf photosynthesis, and the changes in liquid-phase conductance, cell wall thickness, and chloroplast size contribute to this decline under elevated O-3 conditions.

Summary: Understanding the effects of elevated CO2 concentration and temperature on leaf photosynthesis in maize is important for estimating the impacts of climate change. This study found that increasing temperature enhanced leaf photosynthesis, but at higher temperatures, leaf photosynthesis decreased. Elevated CO2 concentration had a fertilization effect on leaf photosynthesis at high temperatures, and also resulted in an increase in leaf soluble sugar content. Additionally, elevated CO2 concentration decreased leaf transpiration rates.

Summary: Leaf structure plays a crucial role in photosynthesis, but the relationship between a single structural parameter and the overall photosynthetic performance is still debated. In this study, a mechanistic model called eLeaf was developed to capture the photosynthetic performance of rice leaves under various environmental conditions. The model successfully quantified the importance of different elements by analyzing imaging data and biochemical measurements. The results showed that photosynthetic metabolism was the major driver of increased carbon assimilation under elevated CO2 levels, and various structural elements made positive and negative contributions. The findings provide theoretical support for experimental data and highlight the significance of leaf structural plasticity in improving crop photosynthesis.

Summary: This study investigated the effects of leaf anatomical traits and environmental stimuli on the photosynthesis of rice plants. It found that the response of mesophyll conductance to temperature was stronger at the mid-tillering stage and with high nitrogen treatment, which could be attributed to a higher activation energy of the membrane.

Summary: Field trials in Northwestern Argentina were conducted to study the impact of plant density on Chenopodium quinoa achene yield and its relationship with morphology, leaf anatomy, and gas exchange. High plant density caused light competition, resulting in morphological and anatomical changes in quinoa plants. Despite compensatory strategies, such as increased specific leaf area and chloroplasts per palisade cell, the limitations in carbon absorption and gas exchange led to a lower yield compared to low plant density.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
