Summary: In recent years, drought stress caused by global warming has become a major constraint on agriculture. This study extracted MsTHI1 from alfalfa and demonstrated its beneficial impact on improving the resistance of plants to stress conditions. MsTHI1 enhances drought tolerance by strengthening photosynthesis, regulating the antioxidant defense system, maintaining osmotic homeostasis, and mediating plant signal transduction.

Summary: This study evaluated the effectiveness of potassium iodide (KI) in mitigating water deficits and improving fruit quality in tomatoes. The results showed that a concentration of 100 μM of KI increased the yield of tomatoes under a water deficit condition, and also improved antioxidant activity and photosynthetic efficiency, while reducing malondialdehyde levels. Additionally, this concentration of KI promoted better fruit quality through increased antioxidant capacity and a decline in the maturation index.

Summary: The study identified a novel sORF gene IbEGF in sweet potato, which encodes an 83-amino acid polypeptide and is induced by various stresses. Overexpression of IbEGF in transgenic sweet potato enhances drought tolerance, promotes phytohormone signaling pathways, and increases proline accumulation to activate ROS scavenging system. IbEGF protein interacts with IbCOP9-5 alpha, suggesting a role in regulating stress responses in plants.

Summary: This study found that microplastics negatively affect the growth of barley plants by limiting root development and altering enzyme activities in roots. There were differences in carbohydrate and ROS metabolism enzyme activities between leaves and roots under microplastics treatment, as well as distinct changes in phytohormone concentrations. The findings suggest that the phytohormone regulatory network plays a key role in regulating enzyme activities in response to microplastics in barley plants.

Summary: Using physiological and proteomic assays, we found that N deficiency inhibits the growth, and N uptake and assimilation in poplar roots, as well as the levels of phytohormones such as abscisic acid and salicylic acid. On the other hand, high N stimulates these processes and leads to differentially abundant proteins in poplar roots. Our results suggest a correlation between proteomic reconfigurations and physiological alterations in poplars acclimating to changing N availability.

Summary: This study examined the efficiency of the fungal strain Cunninghamella bertholletiae in reducing symptoms of salinity, drought, and heavy metal stresses in tomato plants. The results showed that this fungal strain enhanced plant biomass and growth under stressed conditions and modulated the physiological and biochemical mechanisms of plants. It also regulated the expression of related genes. Therefore, Cunninghamella bertholletiae has the potential to be used as a biofertilizer to reduce plant damage and improve crop endurance under stress conditions.

Summary: Drought has a significant negative impact on wheat production, but silicon supplementation can enhance wheat resistance to drought stress. In this study, the effects of foliar supplementation of silicon on wheat under drought stress at different growth stages were investigated. It was found that moderate water deficit reduced wheat growth and increased osmolyte content and lipid peroxidation. However, silicon application at the anthesis and filling stages improved wheat growth, antioxidant activity, and soluble sugar content, ultimately leading to increased yield. Overall, foliar silicon supplementation, especially at the reproductive stage, effectively alleviated drought-induced yield reduction in wheat.

Summary: Integrating amino acid metabolic pathways into plant defense and immune systems plays a fundamental role in stress acclimation and host-pathogen interactions. This study investigates the isoenzyme families involved in aspartate metabolic pathways in Populus trichocarpa, revealing their importance in plant growth and defense regulation. The research also demonstrates the significant induction of specific isoenzyme genes in response to pathogen infection, leading to perturbations in Asp-related metabolites. The integration of multi-omics data sheds light on the role of Asp as a mediator in metabolite biosynthesis and defense regulation.

Summary: Salinity is a major constraint to crop growth and productivity. This study investigated the effects of different neutral and alkaline salt stress on seed germination and seedling growth of canola. The results showed that alkaline salts more significantly inhibit canola seed germination and seedling growth than neutral salts, and the interactions between pH and salt ions play a crucial role in affecting plant growth.

Summary: This study investigated the use of digestate as a nutrient source and its interactions with biochar when applied to potting mix targeted for localised urban use. The results showed that plant biomass and shoot N concentration increased with digestate addition in a typical nutrient dose-response curve. The application of biochar decreased soil mineral N content and altered the structure of the rhizosphere bacterial community. These findings contribute to optimizing the process of converting urban waste into organic fertilizers, promoting environmental protection and plant growth.

Summary: Straw retention combined with a moderate amount of P fertilizer can improve soil P availability by increasing the proportion of labile P and moderately labile P in soil. The application of straw plus 44 kg P ha(-1) fertilizer resulted in higher activity of P-related enzymes and abundance of phoD gene compared to straw plus 88 kg P ha(-1). Soil organic carbon, C:P ratio, and water organic C were positively correlated with the activity of P-related enzymes and the abundance of phoD gene.

Summary: Phosphorus (P) is a crucial nutrient for plant growth, but its sources are non-renewable, raising concerns for sustainable agriculture and food security. Improving plant P-use efficiency (PUE) is necessary for intensive cropping systems, and this review explores various breeding approaches and tools to enhance PUE in grain legumes. The genetic architecture of PUE traits is complex, influenced by both genetics and the environment. Advances in genomics and functional genomics have provided insights into the underlying genetic mechanisms and pathways related to PUE, while novel breeding schemes and tools offer opportunities for designing P-use-efficient cultivars in low-P environments.

Summary: The difference in photosynthetic phosphorus use efficiency (PPUE) among chickpea genotypes is attributed to optimized allocation to specific foliar phosphorus fractions rather than preferential allocation to specific leaf tissues. Genotypes with high PPUE show lower total foliar phosphorus concentration without slower photosynthetic rates. This study highlights the importance of allocation to different phosphorus fractions in determining PPUE.

Summary: Aluminum toxicity poses a significant threat to wheat productivity and quality on acid soil. This study aims to identify novel genes and genetic loci associated with aluminum tolerance in wheat through genome-wide association study (GWAS) and transcriptome analysis. The results reveal several QTL associated with acid soil tolerance, including a major QTL on chromosome 1A and the known TaALMT1 gene on chromosome 4D. By combining GWAS and RNA-seq analysis, 11 candidate genes related to aluminum tolerance were identified. These findings provide valuable insights into the genetic basis of aluminum tolerance in wheat and can aid in the breeding of tolerant varieties.

Summary: This study investigates the relationships between root nodulation, morphology, carboxylates, and colonisation by arbuscular mycorrhizal fungi (AMF) under varying phosphorus (P) levels and sources. The presence of AMF inhibits shoot growth and branching, decreases total root length and specific root length, increases mean root diameter and root tissue density, and reduces carboxylates. However, the role of AMF in P acquisition differs depending on the P source.

Summary: This study investigated the effect of alfalfa/maize intercropping on yield and phosphorus uptake. The results showed that intercropping increased total yield and phosphorus uptake, while maize had a competitive disadvantage under intercropping. The facilitative effects of intercropping were more pronounced in low phosphorus soils. The intercropping pattern of four rows of maize and six rows of alfalfa was recommended as the most productive cropping pattern.
