Melatonin, a versatile biomolecule, profoundly influences plant growth and resilience through its intricate regulation of metabolic pathways, circadian rhythms, cellular processes. The current study elucidates melatonin's concentration-dependent biphasic effects on dynamics in Arabidopsis thaliana Brassica nigra. While 50 μM melatonin optimized biomass accumulation root elongation, higher concentrations (100 μM) elicited stress responses, underscoring dual role as promoter modulator. Melatonin extended photosynthetic efficiency by modulating chlorophyll carotenoid synthesis diurnally, offering protection against photodamage. Divergent responses between the two species, driven species-specific reprogramming, were evident pigment biosynthesis antioxidant pathways. B. nigra displayed robust activation flavonoid phenylpropanoid cytokinin signaling, enhanced oxidative defenses, contrasting with A. thaliana, where suppressed precursors activation. Metabolomic analysis revealed orchestration hormonal crosstalk, involving auxins, gibberellins, jasmonates, to fine-tune adaptation. Stomatal cell wall fortification highlighted optimizing water-use structural under abiotic stress. Cytogenetic studies confirmed safeguarding genomic integrity, regulating chromatin remodeling, promoting DNA repair mechanisms, demonstrating adaptive strategies Moreover, influenced critical including polyamine biosynthesis, sulfur metabolism, nucleotide regulation, emphasizing multifaceted impact homeostasis. These findings position cornerstone molecule biotechnology, potential applications enhancing crop productivity fluctuating environmental conditions.

Abstract Acute lung injury (ALI) is a clinically critical disease characterized by overwhelming inflammatory response and significant tissue damage with no specific treatment available currently. As key player in the pathogenesis of ALI, macrophages are aberrantly activated polarize toward pro‐inflammatory phenotypes, leading to overzealous inflammation injury. Mitochondria recognized as crucial signaling hub governing macrophage function polarization, deregulation which causatively related defective metabolism macrophages, deregulated inflammation, hence ALI. Herein, an inflammation‐responsive, biomimetic metal‐organic framework (MOF) nanoplatform, termed a127/mito@ZIF@Ma developed, sophistically designed for synergistic delivery macrophage‐derived mitochondria anti‐inflammatory miRNA‐127 antagonist resume pulmonary homeostasis alleviate Notably, membrane encapsulation conferred MOF enhanced transport efficacy both vitro vivo. Therefore, administration nanoparticles accordingly profound protection mice against induced either bacterial or viral infection unnoticeable toxicity. The study thus devises novel MOF‐based nanosystem that integrates transplantation miRNA therapeutics, may open new avenue treating ALI relevant diseases.

Abstract Protein O−GlcNAcylation is a ubiquitous posttranslational modification of cytosolic and nuclear proteins involved in numerous fundamental regulation processes. Investigation by metabolic glycoengineering (MGE) has been carried out for two decades with peracetylated N ‐acetylglucosamine (GlcNAc) ‐acetylgalactosamine derivatives modified varying reporter groups. Recently, it shown that these can result non‐specific protein labeling termed S ‐glyco modification. Here, we report norbornene‐modified GlcNAc protected phosphate at the anomeric position their application MGE. These overcome limitations previously used O−GlcNAc reporters. They do not lead to detectable modification, they efficiently react inverse‐electron‐demand Diels–Alder (IEDDA) reaction, which be even within living cells. Using derivative an ‐acetyl‐2‐thioethyl‐protected phosphate, demonstrate protein‐specific detection several imaging inside cells Förster resonance energy transfer (FRET) visualized confocal fluorescence lifetime microscopy (FLIM).
