Summary: Under phosphate starvation conditions, the quantity of differential proteins in soybean leaves significantly increases, with some involved in translation processes and others accumulated in chlorophyll biosynthetic and carbon metabolic processes. Among the induced proteins, enolase protein GmENO2a is the most significant. Additionally, GmENO2a and GmENO2b are dramatically induced at the transcriptional level, and only these two genes contain the P1BS motif.

Summary: In this study, proteomics and phosphoproteomics were used to analyze the effects of Pi on protein abundance and phosphorylation. The results revealed that Pi affected signaling pathways and various biological processes. Western blot analysis confirmed changes in protein level and phosphorylation of key regulators involved in pre-mRNA alternative splicing. The global proteome and phospho-profiling provided insights into the cell signaling networks rewired by excessive Pi and improved our understanding of the molecular mechanisms of phosphate toxicity.

Summary: In this study, quantitative phosphoproteomics characterization of ccRCC tumor and normal adjacent tissues revealed significant differential regulation of phosphoproteins between tumor and normal tissues. These differentially regulated phosphoproteins are associated with proliferative and migratory behavior of renal tumors. Furthermore, master kinases responsible for phosphorylation of substrates associated with cell proliferation, inflammation, and migration were identified.

Summary: Knockdown of ocn gene in Drosophila testes resulted in smaller testis without germ cells. Through proteomics sequencing, 606 proteins were identified as significantly changed in expression after ocn knockdown. The down-regulation of ocn disturbed key signaling pathways related to cell survival and differentiation.

Summary: The study found that alfalfa seedlings exhibited reduced growth under Pi deficiency, with decreases in plant height, root length, and photosynthesis, while root-to-shoot ratio increased. Comprehensive analysis of metabolites and transcriptomics revealed upregulation of proteins related to Pi absorption and translocation, along with decreases in certain compounds and increases in phosphatases and pyrophosphatases. Alfalfa's response to Pi deficiency involves local systemic signaling pathways, root growth, stress-related responses, hormone signaling, and systemic signaling pathways.

Summary: Phosphorus (P) is an essential nutrient that is easily fixed in soils, leading to most of the soil P existing in the form of inaccessible organic phosphorus (Po), particularly phytate-P. This study identified a Pi-starvation responsive GmPAP15a in soybean, which plays a vital role in phytate-P utilization and is regulated at both transcriptional and glycosylation modification levels. The results highlight the GmPHR9/GmPHR32-GmPAP15a signaling pathway that controls phytate-P utilization in soybean.

Summary: Phosphorus is a limiting nutrient for plant growth. Understanding the molecular mechanisms of plants' response to phosphate starvation is important for breeding crops with higher phosphorus-use efficiency. In Arabidopsis thaliana, GLK1 acts as a positive regulator for phosphate-starvation response via the PHR1-dependent pathway. It increases the transcription activity of PHR1 and regulates multiple responses to inorganic orthophosphate starvation.

Summary: Phosphate (Pi), the main form of inorganic phosphorus that can be absorbed by plants, is one of the most limiting macro-nutrients in plants. Few rice NAC members have been reported to be involved in the signaling pathways of Pi homeostasis in plants. This study found that OsNAC016 negatively regulates rice phosphate-starvation response and leaf inclination by activating OsSPX2 expression under Pi-starvation conditions.

Summary: Researchers introduced a functionally tunable material and strategy, extracellular vesicles to phosphoproteins (EVTOP), for monitoring disease-relevant phosphorylation events in circulating biofluids. EVs were efficiently isolated by magnetic beads and enriched for phosphopeptides for phosphoproteomic analyses. This platform enables the quantitative detection of a large number of EV phosphopeptides in a small volume of biofluids, presenting broad clinical applications.

Summary: The response mechanism of denitrifying phosphate-accumulating organisms (DPAOs) under starvation conditions was investigated. The decay of metabolic activity contributed to the damaged denitrifying phosphorus removal (DPR) performance, while the biomass decay had a smaller impact. The genus Dechloromonas, affiliated to DPAOs, exhibited stronger adaptability to starvation.

Summary: Phosphorus is a vital nutrient for crop productivity, but its low solubility in soil often leads to phosphorus deficiency in plants. The study identified two cotton genes, GhPHT1;4 and GhPHT1;5, which play a role in phosphorus uptake and participate in root architecture modification and phosphorus starvation response in cotton.

Summary: This study used proteomics to investigate the interaction between P. brassicae pathotype 3 and canola, revealing the involvement of proteins related to calcium signaling, reactive oxygen species (ROS) biochemistry, thaumatin, and other factors. In addition, several proteins orthologous to known clubroot resistance (CR) genes were identified. This research improves our understanding of the protein-level mechanisms involved in canola's response to P. brassicae and provides insights for developing CR cultivars.

Summary: Hydraulic fracturing uses water and proppants to extract oil and gas, but the resulting wastewater, called flowback and produced water (FPW), contains toxic compounds. Previous research has shown the toxicity of FPW to Daphnia magna (D. magna). This study found that D. magna was unable to recover from a 48-hour exposure to FPW, and the toxicity persisted for at least 19 days post-exposure. The study highlights the importance of considering long-term effects of FPW remediation in spill scenarios.

Summary: In this study, it was found that AtCPK4 and AtCPK11 positively regulate ABA signal transduction in Arabidopsis through phosphorylation of AtABF4. On the other hand, their closest ortholog RcCDPK1 in castor oil seeds is involved in the control of carbon flux by inhibitory phosphorylation. LC-MS/MS analysis revealed common phosphorylation sites in AtABF4 and its castor ortholog. Several new substrates of AtCPK4/RcCDPK1 were identified, expanding the regulatory networks associated with Ca2+ and ABA signaling, immune responses, and central carbon metabolism.

Summary: To mitigate the effects of climate change, agriculture needs more effective evaluation, selection, and production of crop cultivars to accelerate genotype-to-phenotype connections and the selection of beneficial traits. Machine learning and deep learning algorithms have shown the ability to learn plant growth patterns and detect diseases and stress. However, there is a lack of studies on the differentiation of genotypes grown under different conditions using time-series data.
