Summary: Recent research suggests that metabolism-mediated stomatal closure mechanisms play a crucial role in regulating the differences in stomatal speediness between ferns and angiosperms. Ferns showed a lack of response to ABA and slower stomatal responses to sucrose and mannitol compared to angiosperms. Metabolomics analysis revealed that ferns accumulate more secondary metabolites than primary metabolites throughout the diel course, presenting a potential mechanism for the slower stomatal closure and differences in response to exogenous substances between ferns and angiosperms.

Summary: The study suggests that high stomatal density and unique stomatal responses in Marsileaceae play a critical role in facilitating high rates of gas exchange, but also increase the risk of excessive water loss during drought periods. These adaptations in stomatal physiology were considered essential for the evolution of high photosynthetic capacities in vascular plants and played a key role in the rise of angiosperms during the Cretaceous period.

Summary: The rise in atmospheric CO2 concentration due to climate change has both beneficial and detrimental effects on global food production, affecting photosynthesis, growth, yield, and stress tolerance. Ethylene plays a crucial role in response to CO2. The impact of elevated CO2 on ethylene production, stomatal behavior, and defense against pests and pathogens is complex. High CO2 concentrations are advantageous for postharvest storage.

Summary: This study characterizes the spatial distribution and development of floral stomata in the indica rice variety IR64. Stomatal complexes are found in specific areas of the lemma, palea, and anthers, and are morphologically different from stomata on leaves. Overexpression of the stomatal development regulators OsEPFL9-1 and OsEPF1 leads to changes in stomatal density in rice floral organs. Transcriptomic analysis reveals that floral stomatal development is regulated by the same genetic network as in rice leaves. While changes in floral stomatal density do not impact plant reproduction, overexpression of OsEPF1 alters global gene expression.

Summary: Plant guard cells play a crucial role in regulating stomatal aperture for photosynthesis and transpiration. CO2 serves as an important regulator of stomatal movement, with high levels triggering closure. ROS has been identified as a key component in this regulation, highlighting the complexity of CO2 signaling pathways. Further research is needed to fully understand the molecular mechanisms, particularly related to ROS, involved in these responses.

Summary: This study found that ferns and angiosperms have different strategies for nutrient acquisition and utilization, which may affect their ecological competition. Ferns tend to adopt an opportunistic strategy of limiting growth rate to reduce nitrogen demand and store more pooled nitrate, while angiosperms probably utilize nitrogen nutrition to ensure as much development as possible under low nitrogen stress. Identifying the effects of mineral nutrition on the evolutionary results of ecological competition between plant species remains a challenge.

Summary: High-throughput phenotyping studies are crucial for understanding water use efficiency, stress tolerance, yield, and quality in tomatoes. This study compared UAV remote sensing with leaf-level physiological and agronomic measurements in 91 tomato genotypes, revealing differences between long shelflife (LSL) and non-LSL (CON) genotypes under different irrigation conditions. Remote sensing demonstrated significant relationships with physiological and agronomic measurements, but different regressions were observed for CON and LSL genotypes due to their physiological behavior and response to water deficit. The study shows the potential of remote sensing in optimizing tomato phenotyping processes, but also highlights challenges in including genotypes with different water use efficiency behaviors.

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: Coffee, being one of the most traded commodities globally, exhibits a strong interaction with arbuscular mycorrhizal (AM) fungi. This study explored the mycorrhizal phenotype of two important coffee cultivars under phosphorus limitation and found that fungal colonization significantly increased biomass, photosynthetic efficiency, and plant nutrition. This interaction also led to reorganization of major metabolic pathways.

Summary: The process of crop domestication leads to a reduction in gene expression associated with metabolic diversity, particularly in genes involved in specialized metabolism. The reduction in diversity at the metabolite level has been assumed but never adequately assessed and quantified. This study used high coverage metabolomics to investigate metabolic diversity in common bean and found a shift towards lower diversity and specialization in domesticated bean accessions. Molecular networking analysis enabled a broader annotation of metabolites and revealed a metabolic shift from specialized metabolism to central metabolism upon domestication of this crop.

Summary: Evidence suggests that guard cells have higher rate of phosphoenolpyruvate carboxylase (PEPc)-mediated dark CO2 assimilation than mesophyll cells. However, it is unknown which metabolic pathways are activated following dark CO2 assimilation in guard cells. Furthermore, it remains unclear how the metabolic fluxes throughout the tricarboxylic acid (TCA) cycle and associated pathways are regulated in illuminated guard cells.

Summary: By comparing the leaf functional traits of Oeosporangium tinaei (HHPP) and its diploid parents, it was found that HH has higher investment per unit area of light-capturing surface, lower carbon assimilation rate per unit mass for the same midday water potential, higher non-enzymatic antioxidant capacity, higher carbon content, and lower contents of nitrogen, phosphorus, and other macronutrients compared to PP. These traits allow HH to live in microhabitats with less availability of water and nutrients and have a greater capacity for resurrection. PP, on the other hand, has higher assimilation capacity and lower antioxidant capacity, explaining its preference for more humid and nutrient-rich microhabitats. HHPP traits are mostly intermediate between HH and PP, allowing the allotetraploid to occupy the free niche space left by the diploids.

Summary: This study evaluated the seminal plasma metabolome of Bos indicus Guzera bulls with good and poor sperm freezability. Sixty-two metabolites were identified in the seminal plasma, with fatty acids and conjugates and organic compounds being the predominant metabolites. Multivariate analysis showed a distinct separation of seminal plasma metabolomes between bulls with contrasting sperm freezability. Specific metabolites, such as propanoic acid, d-ribose, and glycine, were found to be associated with good sperm freezability, while heptadecanoic acid and undecanoic acid were predominant in bulls with poor sperm freezability. This study provides important information about the seminal plasma metabolome of tropically adapted bulls and its association with sperm freezability.
