Poplar plantations are often established on nitrogen-poor land, and poplar growth and wood formation are constrained by low nitrogen(LN)availability. However, the molecular mechanisms by which specific genes regulate wood formation in acclimation to LN availability remain unclear. Here,we report a previously unrecognized module, basic region/leucine zipper 55(PtobZIP55)–PtoMYB170,which regulates the wood formation of Populus tomentosa in acclimation to LN ***55 was highly expressed in poplar wood and induced by LN. Altered wood anatomical properties and increased lignification were detected in PtobZIP55-overexpressing poplars,whereas the opposite results were detected in PtobZIP55-knockout poplars. Molecular and transgenic analyses revealed that PtobZIP55 directly binds to the promoter sequence of PtoMYB170to activate its transcription. The phenotypes of PtoMYB170 transgenic poplars were similar to those of PtobZIP55 transgenic poplars under LN conditions. Further molecular analyses revealed that PtoMYB170 directly bound the promoter sequences of lignin biosynthetic genes to activate their transcription to increase lignin concentrations in LN-treated poplar wood. These results suggest that PtobZIP55 activates PtoMYB170 transcription,which in turn positively regulates lignin biosynthetic genes, increasing lignin deposition in the wood of P. tomentosa in the context of acclimation to LN availability.

Objective To investigate the inhibitory effect of Tanreqing Injection(TRQ)on the activation of nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3(NLRP3)inflammasome in macrophages infected with influenza A virus and the underlying mechanism based on mitophagy *** The inflammatory model of murine macrophage J774A.1 induced by influenza A virus[strain A/Puerto Rico/8/1934(H1N1),PR8]was constructed and treated by TRQ,while the mitochondria-targeted antioxidant Mito-TEMPO and autophagy specific inhibitor 3-methyladenine(3-MA)were used as controls to intensively study the anti-inflammatory mechanism of TRQ based on mitophagy-mitochondrial reactive oxygen species(mtROS)-NLRP3 inflammasome *** levels of NLRP3,Caspase-1 p20,microtubule-associated protein 1 light chain 3 Ⅱ(LC3Ⅱ)and P62 proteins were measured by Western *** release of interleukin-1β(IL-1β)was tested by enzyme linked immunosorbent assay,the mtROS level was detected by flow cytometry,and the immunofluorescence and co-localization of LC3 and mitochondria were observed under confocal laser scanning *** Similar to the effect of Mito-TEMPO and contrary to the results of 3-MA treatment,TRQ could significantly reduce the expressions of NLRP3,Caspase-1 p20,and autophagy adaptor P62,promote the expression of autophagy marker LC3II,enhance the mitochondrial fluorescence intensity,and inhibit the release of mtROS and IL-1β(all P<0.01).Moreover,LC3 was co-localized with mitochondria,confirming the type of *** TRQ could reduce the level of mtROS by promoting mitophagy in macrophages infected with influenza A virus,thus inhibiting the activation of NLRP3 inflammasome and the release of IL-1β,and attenuating the inflammatory response.

Adsorption Characteristics of Congo Red Dye onto Calcinated Mytilus edulis Shell Powders

引用

Journal of Ocean University of China 2025年第1期24卷 229-237页

Dye wastewater poses a significant threat to aquatic organisms due to its high toxicity. Reducing or eliminating the dye waste from the water is necessary for a healthy and sustainable aquaculture. This study investigated the adsorption properties of Congo red dye on Mytilus edulis shell powders prepared by calcination at 500℃, 700℃, and 900℃. The modified shell powder products were analyzed by SEM（scanning eletron microscopy） and FTIR（fourier transform infrared spectroscopy） for the morphology and structural characterization. The effects of different calcination temperatures, reaction times, reaction temperatures, and initial concentration of Congo red on the adsorption properties were investigated. The adsorption kinetics and isothermal adsorption models were also established. The results revealed that the shell powder calcinated at 900℃ showed the best adsorption capacity on Congo red from aqueous solution. The adsorption reaction reached equilibrium after 150 min and followed by the pseudo-second-order kinetic model. At 25℃, 96.2% of the Congo red in the solution could be removed, and the adsorption capacity could reach at least 1015 mg g–1. The adsorption isotherm is fit with the Freundlich model, indicating a multiphase adsorption process. These results are helpful for cleaning and treating printing and dyeing effluents as well as high-value utilization of shell waste resources.

The Pomacea canaliculata, also known as apple snail, is an invasive species in China, posing a serious threat to agricultural production and public health. To prevent its rampant infestation, we developed a highly efficient snail-killing lead compound, 1-(4-chlorophenyl)-3-(pyridin-3-yl)urea (PBQ). However, the killing mechanism of PBQ remains unclear. To elucidate this, two novel compounds, B-PBQ and J-PBQ, were developed through structural modification of PBQ and were used, through both protein pull-down assay and confocal laser scanning microscopy imaging, to identify and confirm that phosphofructokinase(PFK) in the apple snail is the primary target protein of PBQ. Further studies revealed that PBQ successfully inhibits the activity,content, and expression of PFK in apple snail, disrupting the glycolysis pathway and leading to abnormal energy *** disruptions impair the snail’s tolerance to low oxygen, resulting in its efficient eradication. These findings offer a promising direction for developing next-generation PFK-targeted snail-killing pesticides. Furthermore, the strategy of combining pull-down assays with optical imaging used in this work provides a novel approach for the exploration of mechanisms of other pesticide candidates.
