Summary: Leaf photosynthesis of perennial grasses declines from early to late summer, and water availability is associated with this decline. Despite reduced water availability, the photosynthetic decline is similar in grasses with and without rainfall exclusion, suggesting water deficit is not the sole driver of the decline. Rhizome starch accumulation and sink activity likely explain the observed photosynthetic declines towards the end of the growing season.

Summary: This study investigates the role of source-sink balance in grain filling of tropical rice by comparing two different cultivars. The results show that source capacity and stem nonstructural carbohydrates are significantly associated with the percentage of filled grains, indicating their importance in modulating grain filling. The study suggests that stem nonstructural carbohydrates should be emphasized in the breeding of tropical short-duration rice.

Summary: This study investigated whether wheat plants can resume metabolism after short-term cyclical periods of drought and if the reaction to subsequent stress is the same. The results revealed an accumulation of sugars, proline, and malic acid after short-term drought, but the concentrations decreased during recovery. After the second drought, the concentrations of certain metabolites were higher, and the total polar metabolite concentration after rewatering was elevated. These findings confirm the involvement of proline and highlight the responsiveness of soluble carbohydrate metabolism to stress/recovery.

Summary: This study investigated the impact of reducing sink on source in On-palms with a bunch number greater than eight. The study found that removing bunches stabilized yield components and fruit size during mid-Kimri, suggesting a sink limitation. Bunch thinning increased these indicators compared to normal trees with a bunch number between six and eight, indicating a source limitation.

Summary: Although sugar beets are primarily a source of sucrose, they also contain other carbohydrates such as kestose and galactose. This study found that beet roots can be considered a potential source of various carbohydrates, including fructooligosaccharides (FOS) and galactooligosaccharides (GOS). The presence of these carbohydrates in sugar beet tissues may have implications for their use as a direct source of carbohydrates or as raw materials for biosynthesis.

Summary: The study analyzed the source contributions to the foliar fungal microbiome of a C4 grass across different spatial scales, showing that plants were more important sources than soil and that contributions from different plant functional groups were similar. As annual precipitation increased, plant contributions decreased and unexplained variation increased. The results suggest that the dynamics of foliar fungi sourcing are primarily local and affected by dispersal limitation and environmental filtering.

Summary: The storage of non-structural carbohydrates in internodes plays a crucial role as a carbon source for rice grain filling. Dynamics of dry matter in internodes showed a clear pattern of increase before peaking and then dropping, corresponding with the rate of grain filling. Nitrogen fertilization significantly increased the translocation of internode reserves, indicating its importance for yield formation.

Summary: Balancing source and sink is crucial for fruit load capacity in date palm trees. This study identified the optimal number of suckers, as active sinks competing with berries, to be kept on 'Mazafati' date palms with a normal fruit load. The results showed that a higher number of suckers led to source limitations and reduced yield, weight, size, and flavor of the fruit. Date palms with 4-5 suckers were determined to have the optimal fruit load.

Summary: This study investigated the CO ionization process within the framework of time-dependent Hartree-Fock theory. Different alignments of the CO molecular axis and laser polarization direction were considered under two laser intensities. The results showed that the contribution of inner valence molecular orbitals to CO ionization increased with higher laser intensity, and orbital switching effects could occur at shorter wavelengths due to peak intensity variation.

Summary: This article investigates the short-term effects of drought on root non-structural carbohydrates (NSC) and carbon (C) exudation in a Dahurian larch plantation. The results show significant temporal variations in root NSC and C exudation, with a decreasing trend from July to September. Drought induced an increase in root NSC in July and a marginal increase in root C exudation throughout the drought treatment period. Additionally, root traits were correlated with root C exudation. It is important to consider temporal dynamics and root traits when assessing plant response to drought.

Summary: The contamination of saline soil with hazardous petroleum hydrocarbons is a global issue. Bioaugmentation combined with chemical treatment is an emerging technique, but it currently shows low efficiency under high saline environments. In this study, a halotolerant lipolytic fungal consortium (HLFC) combined with hematite (Fe2O3) was used for the bioremediation of diesel contaminated saline soils. TPH degradation was significantly enhanced in hematite-HLFC and HLFC amended microcosms across all salinity levels, and the microbial community structure showed positive changes. Our findings provide a promising new microbial-based technique for efficient TPH degradation in saline soil.

Summary: Wildfires are a global crisis and current fire models need improvement in capturing vegetation response to changing climate. The representation of woody vegetation in fire models needs renewed focus due to the increasing importance of vegetation dynamics to fire behavior. A process-based approach linking plant water and carbon dynamics to fire behavior and effects could improve the accuracy of current coarse scale fire models and strengthen the science needed for future fire management.

Summary: Different climate teleconnections have varying impacts on burned area in different regions of China. The North Atlantic Oscillation and Antarctic Oscillation exert contrasting effects on fire weather across latitude, resulting in diverging trends in burned area. El Nino Southern Oscillation and other examined teleconnections have minor effects on burned area. The increasing burned area in the NE-mixed forests pyroregion suggests that mega-fires may increase under global warming but will be modulated by potential changes in NAO and AAO.

Summary: Wildfires in southwest Europe during the 2022 fire season have been extreme, with burned areas exceeding the median of the past 20 years. The occurrence of large wildfires started earlier than usual and was associated with abnormally dry fuel, high atmospheric water demand, and pyrometeorological conditions. Nearly half of the season had historically low live fuel moisture content in some regions. The majority of burned areas and impacts on protected areas were caused by a few large wildfires. Shrublands, transitional woodlands, and conifer forests were the most affected land cover types. Climate change will likely make such fire seasons the new normal and pose major economic risks. Effective fuel management in protected areas is crucial to prevent biodiversity loss and landscape degradation. Fire prevention should be explicitly addressed in forest legislation and strategies at the continental scale to mitigate these impacts.

Summary: Cadmium contamination is a significant problem for both plants and human health in China. Finding a way to cultivate safe and high-yielding rice in Cd-contaminated alkaline soils remains a challenge. Through small-scale and large-scale field experiments, it was concluded that a combination of humic acid, foliar and soil silicate fertilization, and shallow plowing produced the best results in terms of low soil bioavailable Cd, low grain Cd concentrations, and high grain yield. Rice farmers are advised to adopt this combination for high-yield, low Cd rice production in alkaline soils.

Summary: Mixed-species plantations of Acacia mangium with 56 native species showed better forest productivity and soil fertility compared to monocultures of A. mangium. The mixed-species plantations promoted the accumulation of soil organic carbon, total nitrogen, and available phosphorus, as well as improved forest regeneration and growth. Thus, introducing multiple native species into A. mangium monocultures is suggested for management in subtropical regions.

Summary: Establishing the temperature dependence of respiration is crucial for understanding the global carbon cycle. Recent studies suggest that the sensitivity of respiration to temperature could be time-dependent, potentially driven by endogenous processes like the circadian clock. By studying different plant species, we found that the sensitivity of respiration to temperature varies temporally and may be influenced by circadian gating.

Summary: Using a fruit removal experiment, the authors tested whether preventing fruit development would increase nutrient and carbohydrates storage and modify allocation to reproduction and vegetative growth the following year. The results showed that fruit removal prevented the depletion of nitrogen and zinc in leaves during fruit growth, and modified the seasonal dynamics in zinc, potassium and starch in twigs. Fruit removal increased the production of female flowers and leaves the following year, and decreased the production of male flowers.
