Summary: Iron (Fe) and phosphorus (P) are essential mineral nutrients for plant growth, and their molecular interactions in crops remain unclear. This study analyzed the physiological and molecular responses of hexaploid wheat to individual and combined Fe and P deficiencies, revealing significant gene expression changes and metabolite accumulation, providing insights for developing strategies to enhance crop resilience in limited nutrient conditions.

Summary: This study investigated the effects of methyl jasmonate (MJ) on wheat seedlings and the fatty acid (FA) content of leaves under optimal and cadmium (Cd) stress conditions. The results showed that MJ had no effect on the height and net photosynthesis rate under optimal growth conditions, but it increased biomass accumulation and net photosynthesis rate under Cd stress. The positive effects of MJ may be associated with lower Cd content and higher alpha-linoleic acid (ALA) content in leaves.

Summary: Wheat plants were treated with three different levels of phosphate deficiency to study the metabolic adaptations and differences in metabolites. It was found that carbohydrate and amino acid metabolism were more affected in shoots, while secondary metabolism was more affected in roots in both types of phosphate deficiency. Several metabolites highly sensitive to phosphate deficiency were also identified. These findings provide new insights into wheat's metabolic pathways under phosphate deficiency and contribute to better handling of future phosphate scenarios.

Summary: The intensive development of nanotechnology has led to the widespread use of nanoparticles in various fields. This study demonstrates that gold nanoparticles can enhance the freezing tolerance of plants, acting as adaptogens. By soaking wheat seeds in solutions of gold nanoparticles, an increase in freezing tolerance of wheat seedlings was observed. The study also establishes a relationship between the increase in freezing tolerance and changes in important indicators for growth, photosynthetic activity, oxidative processes, and sugar accumulation in the seedlings.

Summary: The transformation efficiency of wheat embryos was improved using a combination of special chemical and physical methods with the PureWheat technique. Scanning electron microscopy (SEM), transcriptome analysis and metabolome analysis were conducted to understand the reaction of immature embryos infected by Agrobacterium tumefaciens in PureWheat. The SEM analysis revealed that Agrobacterium tumefaciens was deposited under the damaged cortex of embryos and contacted the receptor cells to improve transformation efficiency. Transcriptome analysis showed that differentially expressed genes were involved in various metabolic pathways and signaling pathways, indicating the energy-demanding process of Agrobacterium infection. This study provides insights into the physiological and molecular changes of wheat embryos during the co-culture stage and sheds light on Agrobacterium-mediated transgenic experiments.

Summary: In this study, we examined the photosynthetic traits of pre-existing and newly developed flag leaves of four wheat genotypes grown in controlled-environment experiments. We found that newly developed leaves were able to acclimate to warm nights and showed increased photosynthetic capacity, while pre-existing leaves exhibited varied responses. The findings highlight the impact of night-time warming on the ability of wheat plants to photosynthesize during the day, with different acclimation capacities between newly developed and pre-existing leaves.

Summary: This study investigated the fungal endophytic microbiome in wheat from seed to plant to seeds, and examined the effects of host genotype, environment, and fungal sources on shaping the microbiome. The results showed that host genotype, tissue type, and abiotic factors significantly influenced fungal communities, with location-independent effects of host genotype on leaves and roots. Phyllosphere microbiome was mostly affected by location-dependent weather conditions, while root communities were less influenced by abiotic factors.

Summary: Plants have different metabolic fluxes between day and night, and protein machinery requires differential maintenance. Light-harvesting complex proteins have faster synthesis and degradation rates during the day, while carbon metabolism and vesicle trafficking components are translated at similar rates day or night. Despite reduced protein synthesis rates at night, few leaf proteins change in abundance between day and night, indicating tightly coordinated protein degradation rates.

Summary: Sulfur is an essential element for plant and human health, and its incorporation into the food chain relies heavily on plant uptake. The dietary requirements for sulfur are based on the synthesis of proteins, enzymes, co-enzymes, vitamins, and hormones. While sulfur-containing amino acids are abundant in animal sources, the variety and quantity of sulfur-containing compounds in plants also have wide-ranging effects on human health. The role of sulfur in redox biochemistry protects against oxidative stress and inflammation, which is consistent with cardiometabolic dysfunction and many chronic metabolic diseases.

Summary: Pomegranate is a polyphenol-rich food and medicinal plant that contains various beneficial compounds. Studies have shown that these compounds can target brain cells and support their functions by regulating redox balance, proliferation, and survival. The neuroprotective effects of pomegranate are mediated by its antioxidant and anti-inflammatory properties, ability to activate signaling pathways, and regulation of mitochondrial damage. In vitro and in vivo studies have demonstrated that pomegranate polyphenols can directly affect neuronal and glial cells, as well as influence blood-brain barrier function and increase blood flow to the brain.

Summary: Plant respiration is a vital process that can be enhanced to increase crop yield. To achieve this, a comprehensive understanding of respiratory substrates and their transport into and out of mitochondria is crucial. The identification of unidentified mitochondrial carriers and catabolic pathways is necessary to determine direct and indirect respiratory substrates. This review discusses the usage of direct respiratory substrates under normal and stressed conditions, suggesting the introduction of enzymes to enable new substrates and comparing them based on energetic yields and oxidation during cell catabolism. The information provided can guide the use of synthetic biology to optimize plant respiration.

Summary: This review discusses the seven inherent plant capacities necessary for reproductive success under abiotic stresses, such as drought, salinity, flooding, temperature extremes, and nutrient stress. These capacities enable plants to continue growing and achieve productive yields in spite of reduced rates. The review highlights the importance of these capacities in major crop species' reproductive success under various stress conditions and provides clarity on the term "oxidative stress," allowing for the identification of key responses that can be targeted for plant breeding.

Summary: Iron is a crucial micronutrient for plants, especially in mitochondrial electron transfer reactions. In this study, the role of Mitochondrial Iron Transporters (MIT) in Arabidopsis thaliana was investigated. It was found that single mutant plants for either AtMIT1 or AtMIT2 showed no phenotypic defects, but when the double mutant Atmit1 Atmit2 was created, multiple developmental defects were observed. RNA-Seq analysis revealed differential expression of over 760 genes, including those involved in iron transport, coumarin metabolism, hormone metabolism, root development, and stress response. Furthermore, a phenomenon of T-DNA suppression and mitochondrial perturbation was observed in the second generation of Atmit1 Atmit2 double mutant plants. Finally, targeted proteomic analysis showed that a protein level of 30% of MIT2 is sufficient for normal plant growth under iron-sufficient conditions.
