Summary: The study found that water and energy co-regulate the spatial heterogeneity in drought resistance and resilience of global vegetation. Increased water availability is positively correlated with increased drought resistance, while increased energy is positively correlated with increased drought resilience. There is a negative correlation between resistance and resilience across different biomes, but the strength of the negative correlation varies based on water and energy conditions.

Summary: Rolled leaf (RL) is a morphological strategy to protect plants from dehydration under stressed field conditions. Quantitative trait loci (QTLs) for RL were identified on chromosomes 1A (QRl.hwwg-1AS) and 5A (QRl.hwwg-5AL), explaining up to 56% and 20% of the phenotypic variation, respectively. The analysis of recombinants delimited QRl.hwwg-1AS to a 6.04 Mb physical interval, providing the foundation for finer mapping and map-based cloning of QRl.hwwg-1AS.

Summary: This study investigates the impact of drought stress on the relationship between plant structure and function in temperate grasslands. The results suggest that rain exclusion does not alter the relationship between foliar traits and water-use efficiency. However, leaf morphology, life history strategy, and phylogenetic distance can predict water-use efficiency in different plant species.

Summary: This study finds that tropical dry forests (TDFs) are resilient to water stress and droughts, increasing their rain use efficiency (RUE) in drier years and recovering to average RUE in the year following the drought. Over the past 18 years, TDF productivity trends are spatially clustered, with increased productivity in the northern hemisphere, no change in equatorial regions, and decreased productivity in the southern hemisphere. The results suggest that TDFs will be resilient under future climatic conditions, particularly with increasing drought conditions.

Summary: The responses of ecosystem water use efficiency (WUE) to environmental perturbations are nonlinear and depend on the strength of the coupling between water and carbon cycles. Two explainable machine learning models were used to evaluate the structure of these nonlinearities and assess the effects of temperature, precipitation, radiation, CO2 concentration, and nitrogen deposition on WUE. The findings showed that precipitation plays a dominant role in shaping the spatial pattern of WUE, while temperature and radiation have negative effects. The study also identified key sensitivities and thresholds in WUE to environmental controls over space and time.

Summary: Decreased light conditions due to cloud cover and smog pollution severely limit crop cultivation and production. Reduced light interception coupled with irregular rainfall caused damage to major crops' yield at their critical growth stages, especially at the post-silking stage in maize (Zea mays L.). The combination of drought and shading stress during the post-silking stage in maize caused a significant reduction in rain yield by altering antioxidant potential and photosynthetic efficiency.

Summary: Cold and drought stresses have negative effects on wheat growth and development, resulting in severe damage and yield losses. This meta-analysis evaluated the risks of cold and drought associations in spring and winter wheat by analyzing 4000 observations and 149 peer-reviewed publications from 2000 to 2021. The results showed that both wheat types exhibited lower tolerance under combined stresses, with a decline in antioxidant enzyme activities and an increase in reactive oxygen species. Winter wheat showed better performance in chlorophyll and chlorophyll fluorescence compared to spring wheat under individual and combined stresses. The Lethal Temperature 50% plant population (LT50) was -15 degrees C for winter wheat and -10 degrees C for spring wheat, indicating the different cold tolerance levels. Grain weight was significantly reduced under drought in spring wheat and cold in winter wheat, with combined stresses affecting grain weight in spring wheat but not in winter wheat. The study also identified water potential, proline, and stomatal conductance as important variables for estimating cold, drought, and combined stresses. Exogenous salicylic acid was recommended as a management strategy to regulate antioxidant enzymes, leaf chlorophyll contents, and water potential to improve photosynthesis under interactive stresses.

Summary: This study evaluated the potential of co-application of biochar and seed priming with nano-sized chitosan-proline to improve salt tolerance in bread wheat. The results showed that seed priming with nano-proline and biochar application significantly improved plant growth and carbon assimilation. The combined use of biochar and nano-priming was more effective in improving salt tolerance in tested wheat genotypes than the sole application. The mechanisms involved in improving salt tolerance included ionic homeostasis, activation of the antioxidant defense system, and osmotic adjustment.

Summary: Wheat grain quality is influenced by compositional and physical properties, with threshold levels set based on end-use requirements. Heat stress leads to a reduction in grain yield by limiting resource translocation and decreasing grain size and starch content, while increasing gliadin content. It also affects the appearance, weight, hardness, protein, starch and mineral content, flour yield, and dough handling properties. The extent of these changes depends on the timing, severity, and wheat genotype. This review discusses the impact of heat stress on flower development, fertilization, grain development, and reproductive failure, as well as the associated biochemical and molecular mechanisms.

Summary: Cadmium is a carcinogenic element with no significant role in plant growth. Accumulated cadmium in plants can enter the food chain and pose human health risks. Recent research has focused on reducing cadmium uptake and accumulation in cacao beans. Various approaches such as biochar, organic amendments, and inorganic amendments have been proposed to immobilize cadmium in soil and alleviate its toxic effects. The selection of low cadmium-accumulating genotypes may also be a promising strategy to decrease cadmium contents in cacao beans.

Summary: An experiment was conducted to optimize different organic amendments for sugar beet production and root quality. Among the amendments, poultry manure at an optimized rate of 20 t ha(-1) showed the most effective results in terms of root yield, sugar yield, and sugar quality. The improved yield was attributed to better leaf growth and root yield, resulting in higher reserve accumulation in roots. The 'California' genotype performed better than the 'Serenada' genotype. Therefore, growing the 'California' genotype in sandy loam soils with poultry manure application (20 t ha(-1)) could be a practical option for improving sugar beet yield and sugar recovery.
