Summary: The study by Navarro and colleagues reveals that arsenite can regulate the uptake and detoxification of arsenate in plants under low-phosphate conditions by controlling the stability of PHOSPHATE STARVATION RESPONSE 1. This finding opens up new opportunities for researching mitigation strategies to address arsenic toxicity in plants.

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: Soil nutrient restrictions, especially phosphorus, significantly limit plant growth and development. Plants have developed intricate mechanisms to maintain phosphorus homeostasis and regulate its acquisition, translocation, and recycling. While research on phosphorus utilization in annual plants has advanced, studies on woody perennial plants are still limited.

Summary: This review summarizes recent progress in understanding the mechanisms by which the strigolactone pathway integrates sugar, metabolite, and nutrient signals. The study demonstrates that strigolactones and MAX2-dependent signaling play pivotal roles in mediating the effects of nutritional and metabolic cues on plant development and metabolism. Additionally, the authors discuss the implications of these interactions for plant evolution and adaptation to the environment. Overall, this review provides new insights into the role of strigolactone signaling in integrating nutritional and metabolic status and its consequences for plant development and architecture.

Summary: Phosphorus is crucial for plant growth, and plants have developed sophisticated mechanisms to regulate the uptake and utilization of phosphate in response to changing environments. Recent research has focused on understanding the molecular regulatory mechanisms of phosphate transporters in plants such as Arabidopsis and rice, aiming to improve plant phosphorus efficiency through genetic enhancement.

Summary: This study investigated the effects of a Fe(3+)-based phosphate binder on the oral and gastrointestinal microbiome of hemodialysis patients. Overall, the microbiome did not change significantly, but there were individual differences. Bacterial taxa that benefited from iron abundance lacked iron-binding siderophores or alternatives, while those that declined under iron abundance possessed these alternatives. Patients with microbiome shift were younger and had higher serum phosphate concentrations.

Summary: This study demonstrates the use of intramolecular C-13/C-12 analysis to understand carbon uptake and allocation in plants, providing more comprehensive assessments of carbon metabolism than whole-molecule C-13/C-12 analysis. The research also proposes experimentally testable theories on the origin of the intramolecular signal.

Summary: Sex differences exist in acute phosphate homeostasis. Females may mobilize and excrete more calcium and phosphate in response to oral phosphate compared to males. Females may be more vulnerable to the negative impact of high levels of dietary phosphate.

Summary: GSH is an essential thiol for plants, but its degradation has not been fully elucidated, limiting our understanding of plant life. Recent studies have shown that GSH is degraded by cytosolic enzymes or after conjugation with other molecules. This highlights the need to reassess previous assumptions and provide a novel overview of the plant GSH degradation pathway. This review aims to summarize current understanding of GSH/glutathione conjugate degradation and lay a foundation for future studies.

Summary: WRKY transcription factors play crucial roles in plants' response to abiotic stress. Phosphate starvation is a major challenge for plants, and understanding the molecular mechanisms of phosphate absorption and transport from the soil is important for optimizing phosphate acquisition efficiency in plants. In this review, recent advances in the study of complex WRKY TF networks that regulate phosphate acquisition and maintain phosphate homeostasis in plants are summarized. The transcriptional regulation and functions of these WRKY TFs in plant growth and development processes, such as flowering, leaf senescence, and seed germination under phosphate limitation, are also analyzed. This review provides a basis for potential guidelines to develop plant cultivars with improved phosphate uptake and utilization for sustainable agricultural and forestry development.

Summary: The biosynthesis, levels, signaling, and possible roles of melatonin and its metabolites in plants were summarized. Different plants have differential levels of melatonin and its metabolites, leading to varying physiological effects. Melatonin mediates important functions in growth stimulation and stress tolerance through its antioxidant activity and function in activating the MAPK cascade.

Summary: Significant progress has been made on plant phosphorus nutrition at the molecular level, but there is a need to integrate information from various disciplines. Strategies to mobilize phosphorus in low-P soil are found to be more effective than mycorrhizal strategies. Understanding the trade-offs of different investment patterns in phosphorus fractions is crucial for optimizing plant growth.
