Rice blast, caused by Magnaporthe oryzae , is a devastating disease threatening global rice production, with
current control strategies facing resistance and environmental risks.
Small bioactive peptides have emerged as promising eco-friendly plant
immunomodulators with low resistance risk for sustainable crop disease
control. Here, we identified cyclic dipeptide cyclo(Val-Pro) as a
potential plant immunomodulator with no direct fungicidal activity,
which effectively conferred robust rice resistance to M. oryzae via promoting host intrinsic defense responses.
Pre-treatment with cyclo(Val-Pro) activated salicylic acid (SA)- and
jasmonic acid (JA)-mediated innate immunity, triggered reactive oxygen
species (ROS) accumulation and callose deposition, and modulated core
circadian clock genes in rice leaves. Transcriptomic and metabolomic
analysis revealed that optimal blast resistance efficacy by cyclo(Val-Pro)
pre-treatment at 14:00 was associated with circadian clock regulation
and metabolic reprogramming. Specifically, cyclo(Val-Pro) rewired
phenylpropanoid and tryptophan metabolism in rice leaves, and tryptamine
was validated as a key functional downstream metabolite.

Benzyl nitrile from tea plants attacked by various pests displays a diurnal pattern, which may be closely regulated by the endogenous circadian clock. However, the molecular mechanism by the circadian clock of tea plants that regulates the biosynthesis and release of volatiles remains unclear. In this study, the circadian clock gene CsPCL1 can activate both the expression of the benzyl nitrile biosynthesis-related gene CsCYP79 and the jasmonic acid signaling-related transcription factor CsMYC2 involved in upregulating CsCYP79 gene, thereby resulting in the accumulation and release of benzyl nitrile. Therefore, the anti-insect function of benzyl nitrile was explored in the laboratory. The application of slow-release beads of benzyl nitrile in tea plantations significantly reduced the number of tea geometrids and had positive effects on the yield of fresh tea leaves. These findings reveal the potential utility of herbivore-induced plant volatiles for the green control of pests in tea plantations.

Here, we demonstrate a g-C3N4@Au@SrAl2O4:Eu2+,Dy3+ composite as a novel efficient self-luminous visible-light plasmonic photocatalyst for photocatalytic degradation of organic pollutants and hydrogen evolution from water around the clock. The g-C3N4@Au@SrAl2O4:Eu2+,Dy3+ composite was prepared by integrating a g-C3N4@Au plasmonic photocatalyst composite with a SrAl2O4:Eu2+,Dy3+ long-afterglow phosphor through a simple Pechini-type sol–gel method followed by a mechanical mixing and high-temperature calcination process. Owing to the synergistic effect of surface plasmon resonance of the Au nanoparticles in g-C3N4 and long-lasting phosphorescence of the SrAl2O4:Eu2+,Dy3+ phosphor, the prepared g-C3N4@Au@SrAl2O4:Eu2+,Dy3+ composite shows a continuous and efficient photocatalytic activity for photocatalytic degradation of organic pollutants and hydrogen evolution from water in a sunless environment. The current research study could provide a new strategy for designing a highly efficient composite photocatalyst for solar environmental purification and hydrogen energy production around the clock.

To achieve an effective and straightforward method for Cr(VI) removal from industrial wastewater, a composite Bi 2 S 3 /PDA/PEI material (BSPP) was successfully prepared through in-situ polymerization of polydopamine (PDA) followed by chemical grafting with polyethylenimine (PEI) on the surface of Bi 2 S 3 materials for round-the-clock highly efficient Cr(VI) removal from actual industrial electroplating wastewater. Under dark conditions, the maximum adsorption capacity of Cr(VI) by BSPP reaches 780.75 mg/g. Interestingly, when exposed to light, the maximum Cr(VI) removal capacity was further increased to 1333.21 mg/g. X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma optical emission spectrometry (ICP-OES) analyses indicate that BSPP not only reduces Cr(VI) to Cr(III) under light condition, but also facilitates the significant decrease of total chromium content. Notably, under natural sunlight exposure outdoors, BSPP is capable of completely eliminating Cr(VI) from both plating cleaning solutions and waste plating solutions. More importantly, BSPP maintains its original Cr(VI) removal efficiency after nine cycles within plating cleaning solutions and six cycles within waste plating solutions. Large-scale testing results indicate that BSPP can effectively treat substantial volumes of electroplating wastewater to comply with national Cr(VI) discharge standards. These findings suggest that BSPP represents a promising material for continuous 24-hour Cr(VI) treatment in industrial electroplating wastewater.

Persistent light-emitting materials (PLMs), which have the potential to store and release light energy after light irradiation, are receiving increasing attention for their role in prolonging the lifetime of photogenerated electrons for the development of photocatalysts with round-the-clock applications. In this paper, a double S-scheme Sr 2 MgSi 2 O 7 :Eu 2+ ,Dy 3+ /ZnIn 2 S 4 /UiO-66-NH 2 (SZU) heterojunction with round-the-clock catalytic activity was prepared by hydrothermal self-assembly method. The photocatalytic performance of the SZU heterojunction for RhB(MB) degradation was significantly improved compared with the pristine ZnIn 2 S 4 and UiO-66-NH 2 . The SZU heterojunction has excellent catalytic degradation performance for RhB (MB), and the removal rate of RhB (MB) reaches 72.2 % (81.7 %) after visible light irradiation for 40 (60) minutes. After the end of light, the total removal rate of RhB (MB) reached 86.7 % (96.8 %) when the catalysis continued for several hours under dark conditions, which was 14 % and 15 % higher than that under visible light irradiation, respectively. Based on the characteristics of SMS photoluminescence, combined with a large number of photocatalytic experiments, The sustained photocatalytic activity was enhanced under both daytime and darkness conditions, not only because of the production of SZU complexes, which prolonged the visible light response of ZnIn 2 S 4 , but also because of the construction of double S-scheme heterojunctions, which facilitates the light storage capacity, charge transfer, and the separation of photo-induced charge carriers and effectively promoted the photocatalytic activity of the photocatalysts. This work contributes to a deeper understanding of the design of round-the-clock photocatalysts, and provides a useful exploration for the practical application of photocatalytic technology.

Subacute ruminal acidosis, induced by high-concentrate diets, can trigger systemic inflammation and mastitis, a pathology linked to ruminal dysbiosis and disruption of the host's circadian rhythm. In this study, 32 mid-lactating Saanen goats (41.5 ± 1.79 kg BW) were randomly allocated to 4 treatment groups (n = 8/group): a low-concentrate diet (LC; 30:70 concentrate:forage ratio), a high-concentrate diet (HC; 70:30), and their respective counterparts supplemented with 200 mg/kg of DM thiamine (LCT and HCT). Results demonstrated that the HC diet decreased ruminal pH, induced microbial dysbiosis, and increased plasma LPS concentrations. This resulted in systemic and mammary inflammation, characterized by elevated cytokine expression and a significant decline in milk yield and quality. Thiamine supplementation in the high-concentrate diet (HCT group) effectively reversed these changes. It stabilized ruminal pH, modulated the microbiota by enriching beneficial taxa such as f_Ruminococcaceae , reduced inflammatory cytokine levels, and restored milk production. At the molecular level, goats receiving thiamine supplementation exhibited reduced activation of the NF-κB and NLRP3 inflammasome pathways and higher expression of core clock proteins (CLOCK, BMAL1) in the mammary tissue. In conclusion, thiamine alleviates SARA-induced mastitis by stabilizing the rumen microbiota and mitigating inflammation, and these protective effects are associated with concurrent changes in the NF-κB/NLRP3/CLOCK signaling axis in the mammary gland.

Developing a green and efficient technology for decomposing aflatoxin B 1 (AFB 1 ) and ochratoxin A (OTA) in grains has important theoretical value and application prospects for ensuring food safety. A dual Z-scheme ternary heterojunction photocatalyst, Sr 2 MgSi 2 O 7 :Eu 2+ ,Dy 3+ /BiVO 4 /NH 2 -UiO-66 (SBN), was prepared via a self-assembling hydrothermal approach. The SBN heterojunction photocatalyst exhibits round-the-clock photocatalytic activity due to the intrinsic light source of Sr 2 MgSi 2 O 7 : Eu 2+ , Dy 3+ (SMS). Dual Z-scheme mechanism was proposed and validated through detailed analysis of quenching experiments, ESR spectra, band arrangement, and charge transfer processes. The dual Z-scheme mechanism not only promotes the effective transfer and separation of photo generated charge carriers during charge carrier transport, but also maintains significant reduction and oxidation potentials. SBN photocatalyst exhibits stable and persistent photocatalytic performance, significantly enhancing the degradation efficiency of AFB 1 and OTA under all-weather conditions. Experimental data shows that the removal rate of AFB 1 increased from 69.60 % after 60 min of illumination to 83.9 % after 4 h of turning off the light source; At the same time, the removal rate of OTA increased from 64.8 % to 78.1 %. •O 2 − and •OH were identified as key active species in photocatalytic reactions. Based on the analysis of AFB 1 and OTA degradation intermediates and the prediction of degradation sites using density functional theory (DFT), degradation pathways for AFB 1 and OTA were proposed. Collectively, these findings suggest a highly promising practical approach for the detoxification of mycotoxins in grain commodities.

The long-afterglow luminescent material Sr2MgSi2O7:(Eu, Dy) was combined with the photocatalytic material g-C3N4 to construct a type of Sr2MgSi2O7:(Eu, Dy)/g-C3N4 self-luminous photocatalytic composite. This overcomes the limitation that photocatalytic experiments can only be carried out under an external light source, and it provides a more flexible way to use photocatalytic technology in environmental purification. The morphology, structure, luminescence, and photocatalytic properties of the samples were investigated using a variety of advanced characterization techniques. The results show that the significant improvement in the photocatalytic performance is attributed to the formation of a Z-scheme heterojunction between the luminescent and photocatalytic materials and the promotion of the photocatalytic reaction by the properties of the long-afterglow luminescent material itself. A possible mechanism for the photocatalytic process of the composite is proposed, and it is speculated that the reason for the increased photocatalytic activity is internal electron transfer and electron–hole pair separation based on tests such as X-ray photoelectron spectroscopy and density functional theory calculations. This study provides a strategy for enhancing the photocatalytic activity of photocatalysts and achieving round-the-clock degradation of pollutants.
