Summary: The stay-green trait, which delays leaf senescence, is crucial for drought adaptation in cereals. This study identified PIN genes as key regulators of the stay-green phenotype in sorghum. Genetic modification of these genes affected canopy development and root architecture, leading to a stay-green phenotype. This finding has important implications for increasing grain yield under drought conditions.

Summary: This study found that seeds harvested from mother plants grown in a controlled environment had better germination under suboptimal conditions compared to seeds from greenhouse plants. Seedlings from the controlled maternal environment showed better performance in ABA and salinity stress tests. However, greenhouse seedlings displayed less ROS damage and lower electrolyte leakage under dehydration stress compared to controlled environment seedlings.

Summary: The key factors for successful germination and emergence of white clover are light, temperature, planting depth, drought, and salt stress. White clover seeds are negatively photoblastic and show differential responses to temperature. Deeper planting depth leads to lower germination rate, and the optimal depth is <= 1 cm. White clover seeds are highly sensitive to drought and salt stress. These findings provide a foundation for achieving successful establishment of white clover stands.

Summary: This study aimed to investigate the effects of NaCl salinity stress on chlorophyll fluorescence, nutrient uptake, and physiological characteristics of different mint species. The results showed that mint ecotypes E14, E10, and E18 were the most tolerant, displaying a high Fv/Fm index at all salinity levels. Salinity conditions can significantly impact the physiological processes and defense pathways of mint plants, resulting in dramatic changes in plant nutrients, photosynthesis efficiency, and essential oil content.

Summary: The study reveals that nitrogen availability significantly affects drought responses and stem development of Catalpa bungei seedlings, with varying effects under different water treatments. Higher intrinsic water use efficiency (WUEi) under vertically partial root-zone drought contributes to dominant xylem development, while constitutive activation of ABA signaling under long-term horizontally partial root-zone drought suppresses stem growth. Nitrogen addition positively influences xylem development by increasing WUEi and IAA levels under vertically partial root-zone drought conditions.

Summary: Stay-green (SG) genotype of grain sorghum performs better at medium and high N levels under post-flowering drought, showing greater green leaf area, slower senescence rate, more biomass, and higher water and nitrogen use efficiency compared to non-stay-green (NSG) genotype. However, at low N levels, the advantages of SG genotype are not significant. Adequate nitrogen supply is important for SG genotype under drought conditions, and greater root biomass may contribute to higher nitrogen use efficiency in SG genotype.

Summary: Climate change leads to various environmental stresses, including soil salinity, which negatively affects agricultural productivity. Plants respond to salinity stress by regulating ion homeostasis, inducing antioxidant defense systems, and producing phytohormones and osmoprotectants. Enhancing salt tolerance in plants is crucial for sustaining global agricultural productivity.

Summary: Balanced photosynthesis is crucial for plant survival and agricultural benefits. Drought stress disrupts photosynthetic efficiency, but chloroplast retrograde signaling and genetic imprints can help preserve photosynthetic capacity. Agronomic and genetic engineering approaches, along with isoprene regulation, offer potential solutions for rescuing photosynthetic apparatus during drought stress.

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: Plastic film mulching can result in high concentrations of macroplastics (MaPs) and microplastics (MPs) in soils, negatively impacting soil health and crop production. This study investigated the distribution and correlation of MaPs and MPs at different soil depths and plastic mulching years in maize fields in northwest China. The findings revealed that MaPs were mainly concentrated at 0-10 cm soil depth, while MPs were predominantly distributed at 10-20 cm soil depth. The study also estimated the weight of MaPs and MPs in farmland in northwest China in 2020. It emphasized the need for improved recycling efficiencies and management practices of plastic film to ensure food security and sustainable agricultural development.
