Summary: This study assessed the role of the MED16 subunit in Arabidopsis root system remodeling in response to phosphate limitation, showing that it modulates the expression of a large set of low-phosphate-induced genes to increase phosphate absorption in roots. The findings suggest that MED16 is critical for the transcriptional activation of STOP1 targets, including the membrane permease ALMT1, in order to enhance malate exudation in response to low phosphate, shedding light on how plant cells orchestrate root morphogenesis to gene expression with the STOP1-ALMT1 module.

Summary: Jasmonic acid (JA) is a plant hormone that regulates various physiological processes. Inositol pyrophosphates (PP-InsPs) play a role in JA perception. The ITPK1 kinase is involved in JA-dependent root architecture development by controlling the expression of different JAZ repressor proteins.

Summary: AtHSPR forms a complex with KNAT5 and OFP1, regulating primary root growth through GA-mediated root meristem activity. KNAT5-OFP1 acts as a negative regulator of AtHSPR in response to GA. The AtHSPR-KNAT5-OFP1 module regulates root growth and development by impacting the expression of GA biosynthetic gene GA20ox1.

Summary: The study showed that Cs+ accumulation increased by up to 30% in two Arabidopsis mutant lines lacking KUP9 and grown under low K+ supply, suggesting that KUP9 disruption could impair Cs+ efflux while K+ transport remains unaffected. The putative primary role of KUP9 in plants is further discussed.

Summary: Under phosphate starvation, PMT1 and PMT2 are induced to produce phosphocholine for leaf growth maintenance. The growth defect in the pmt1 pmt2 double mutant under phosphate starvation can be rescued by exogenous supplementation of phosphocholine, despite unaffected membrane lipid profiles.

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: The role of autophagy in plant phosphate starvation response is not well understood. In this study, we found that the Arabidopsis genes ATG8f and ATG8h are induced in the roots under low phosphate conditions, and their upregulation correlates with their promoter activities, which can be suppressed in the phr1 mutant.

Summary: Phosphate is the plant-accessible form of phosphorus, and its deficiency limits plant growth. Studies show that phosphate deficiency can lead to over-accumulation of anthocyanins in plants, and SPX4 plays a role in transmitting the phosphate starvation signal to anthocyanin biosynthesis pathways.

Summary: Selective Arabidopsis thaliana inositol phosphate kinase functions modulate response amplitudes in innate immunity by balancing signaling adjustments with phosphate homeostasis networks. Pyrophosphorylation of InsP(6) generates high-energy metabolites InsP(7) and InsP(8) that play crucial roles in plant development and stress responses. Plants are able to regulate immune responses and phosphate homeostasis under phosphate deprivation conditions.

Summary: This study developed a novel strategy for efficient degradation of PGMEA and monoaromatics in wastewater from semiconductor manufacturing processes. The researchers used a flexible Fe-MOF under mild subcritical water conditions to achieve a remarkable degradation performance. The method showed superior mineralization efficiency compared to traditional homogeneous Fenton and Fenton-SCW processes. Real world water samples also demonstrated high removal efficiency. This approach provides a promising and eco-friendly solution for treating semiconductor waste effluents and environmental water matrices containing toxic recalcitrant organics.

Summary: Functionally redundant phosphate phosphatases localized in the endoplasmic reticulum and chloroplast mediate a crucial step of glycerolipid biosynthesis in pollen and seeds of Arabidopsis. Inter-organelle communication is essential in cellular homeostasis, and this study reveals the crosstalk between the endoplasmic reticulum (ER) and chloroplasts in lipid biosynthesis. The differential subcellular localization of lipid phosphate phosphatases (LPPs) affects ER glycerolipid metabolism, and their genetic suppression leads to impaired triacylglycerol biosynthesis.

Summary: Phosphate-selective composite adsorbents, MIL100/Alg and MIL101/Alg, were prepared by incorporating alginate with MIL100 and MIL101. The adsorption capacity of MIL100/Alg and MIL101/Alg for phosphate outperformed their constituting components. N2 sorption analysis revealed the formation of mesoporous structures on the Alg network upon incorporation of MIL100 and MIL101. The composite adsorbents showed excellent selectivity for anionic phosphate and can be easily regenerated. Preliminary economic analysis indicated that MIL100/Alg and MIL101/Alg are economically viable adsorbents.

Summary: Tuberculosis, caused by M. tuberculosis bacteria infection, is a deadly disease. The long-term drug consumption and low patient commitment hinder the success of TB treatment. To overcome these obstacles, biomolecule metal-organic frameworks (BioMOFs) are explored as potential drug carriers. This study successfully synthesized a copper-based BioMOF (Cu-PCA) using a bioactive organic linker and demonstrated its high drug loading capacity and controlled release kinetics. Cu-PCA exhibited antibacterial activity and good biocompatibility.

Summary: Pre-functionalized lipid-dense post-hydrolyzed spent coffee grounds (PHSCG) were used as feedstock for fatty acid methyl ester (FAME) production via non-isothermal in-situ (trans)esterification (ISTE) under subcritical conditions. The study investigates the influence of reactor loading (RL), solvent-to-solid ratio (SSR), temperature, and holding time on the conversion. High FAME yield can be achieved in about 1 h without needing an additional catalyst. The catalytic activity of the residues recovered after ISTE was supported by elemental analysis and FT-IR peak identification.

Summary: This study explores the use of extractives-free SCB as a renewable adsorbent to remove Rhodamine B from water, contributing to environmental conservation and better utilization of natural resources. The adsorption kinetics and equilibrium uptake were assessed under different pH, RhB concentrations, and temperatures. The results show that the Elovich and multi-mechanistic models best describe the adsorption kinetics, and the adsorption is primarily physisorption but may involve chemisorption. The study also reports on the regeneration and reuse of eSCB as an adsorbent for RhB.
