Plants deploy versatile scaffold proteins to intricately modulate complex cell signaling.Among these,RACK1A(Receptors for Activated C Kinase 1A)stands out as a multifaceted scaffold protein functioning as a central integrative hub for diverse signaling pathways.However,the precise mechanisms by which RACK1A orchestrates signal transduction to optimize seedling development remain largely unclear.Here,we demonstrate that RACK1A facilitates hypocotyl elongation by functioning as a flexible platform that connects multiple key components of light signaling pathways.RACK1A interacts with PHYTOCHROME INTERACTING FACTOR(PIF)3,enhances PIF3 binding to the promoter of BBX11 and down-regulates its transcription.Furthermore,RACK1A associates with ELONGATED HYPOCOTYL 5(HY5)to repress HY5 biochemical activity toward target genes,ultimately contributing to hypocotyl elongation.In darkness,RACK1A is targeted by CONSTITUTIVELY PHOTOMORPHOGENIC(COP)1 upon phosphorylation and subjected to COP1-mediated degradation via the 26 S proteasome system.Our findings provide new insights into how plants utilize scaffold proteins to regulate hypocotyl elongation,ensuring proper skoto-and photo-morphogenic development.

Membrane distillation(MD)utilizing low-grade thermal energy can be used to effectively desalinate hypersaline brines with a high freshwater recovery for water reuse.Membrane flux and durability are the two main indices used to evaluate MD membrane performance.In the past decade,electrospun nanofibrous distillation membranes(EFDMs)with a low mass transfer resistance have garnered increasing attention in MD research,owing to their high porosity and interconnected-pore structure.However,on the one hand,the pores of EFDMs compared to those of phase-inversion membranes are easily deformed and impacted by water flow,reducing membrane flux;on the other hand,the general hydrophobic interface is susceptible to being wetted,fouled and scaled during the desalination/concentration process,resulting in MD failure.This review will present a comprehensive discussion of the recent progress in electrospun nanofibers for the MD of hypersaline wastewaters with a focus on designing specially wettable membrane interfaces and welding-pore structured membranes to enhance MD distillation efficiency and durability simultaneously.Besides,the challenges and perspectives of MD in treating hypersaline wastewaters are also provided as a guide for future research on sustainable and clean freshwater recovery.

The design of novel signal amplification elements was key to improving the sensing and analysis performance of electrochemical sensors. In this work, porous one-dimensional copper nitrogen-doped carbon nanofibers(CuNCNFs) were successfully prepared via the coupled process of electrospinning technology and high-temperature pyrolysis. This coupling of multiple processes and the introduction of heteroatoms pyrolyzed the HKUST-1 particles to generate three-dimensional Cu-doped carbon octahedra and mosaic them inside the one-dimensional carbon nitride channels, obtaining small-sized Cu particles while introducing a large number of N species, and constructing a three-dimensional MOFs-derived metal-carbon hybrid one-dimensional multistage carbon nitride structure. The resulting Cu-NCNFs sensor could simultaneously determine acetaminophen and sulfanilamide and exhibit superior electroanalytical performance, reproducibility, stability, and selectivity. This strategy provides a new approach to preparing novel signal amplification elements for the efficient monitoring of micropollutants.

The embryo in maize has a critical role in controlling kernel nutrition components and grain yield.We measured five embryo weight and size traits,six kernel weight and size traits,and five embryo-tokernel ratio traits in a nested association mapping(NAM)population of 611 recombinant inbred lines(RILs)derived from four inbred lines including the high-oil,giant-embryo line BY815 as the common parent.Using three statistical methods,we identified 5–22 quantitative trait loci(QTL)for each trait,explaining 4.7%–46.7%of the phenotypic variation.The genetic architecture of maize embryo size and its related traits appeared to be dominated by multiple small-effect loci with little epistasis,and the genetic control underlying embryo size appeared to be distinct from that underlying kernel size.A trait–QTL association network included 205 nodes and 439 edges and revealed 28 key loci associated with at least three traits.Cloned maize genes including Zm Urb2,Emp12 and Zm BAM1 d,maize orthologs of known rice genes that control seed size including BG1,XIAO and GS9,and 11 maize orthologs of Arabidopsis EMBRYO-DEFECTIVE(EMB)genes were identified as underlying these key loci.Further,the phenotypic and genetic relationships between embryo size and kernel size were evaluated,and genetic patterns for identified loci that control embryo size and its related traits were proposed.Our findings reveal distinct genetic architectures for embryo size,kernel size,and embryo-to-kernel ratio traits and establish a foundation for the improvement of embryo-size-mediated kernel nutrition and grain yield.

CONSPECTUS:Nanoporous carbon(NPC)materials with various architectures have attracted considerable attention because of their distinctive properties and great application potential in environmental remediation,energy conversion and storage,advanced sensors,and other applications.Traditional methods for the synthesis of NPCs,for example,the pyrolysis of natural products or polymers,template-assisted synthesis,and using deep-eutectic solvents,always involve toxic precursors and complex procedures,which greatly hinder further applications.Therefore,it is highly desirable to explore simple and feasible ways to prepare NPCs.Furthermore,to improve the performance and extend the application fields of NPCs,efficient strategies should be developed to regulate the components at the atomic level and construct multidimensional architectures.

On September 5, 2022, the Luding M6.8 earthquake occurred in the Moxi-Shimian segment of the Xianshuihe fault, coinciding with the historical ruptured zone of the 1786 Moxi earthquake. Its seismogenic environment provides a foundation for comprehending the mechanism of the earthquake and its future hazard. In the Moxi-Shimian segment, we establish a series of near-field Global Navigation Satellite Systems（GNSS） stations to enhance the spatial resolution of observational data for the inversion of the interseismic kinematic parameters. In this study, with an elastic screw dislocation model constrained by GNSS observations, the slip rate of the Moxi-Shimian segment is estimated to be10.9 ± 1.0 mm/yr, while the locking depth is 15.7 ± 6.2 km. Additionally, we utilize a block-dislocation model to invert the interseismic fault coupling along the Kangding-Moxi-Shimian segment. The result indicates a gradual deepening of the locking depth along the section from Kangding to Shimian. The coseismic rupture of the 2022 event occurred within the high coupling regions in the Kangding-MoxiShimian segment, which indicates that the rupture kinematics in this event might be controlled by the interseismic deformation. The seismic moment accumulated within the ruptured zone of the Luding earthquake since 1786 ranges in [1.42-3.40] × 1019N·m, which is significantly greater than the seismic moment released during the 2022 event. As a result, we infer that the Luding earthquake released only a portion of the accumulated energy within the original rupture zone since 1786, indicating that the 2022 event has not caused a complete rupture in the Moxi-Shimian segment. Consequently, there remains a substantial seismic hazard in this area.

Background and Aims:Correct identification of small hepa-tocellular carcinomas(HCCs)and benign nodules in cirrhosis remains challenging,quantitative apparent diffusion coeffi-cients(ADCs)have shown potential value in characterization of benign and malignant liver lesions.We aimed to explore the added value of ADCs in the identification of small(≤3 cm)HCCs and benign nodules categorized as liver Imag-ing Reporting and Data System(li-RADS)3(LR-3)and 4(LR-4)in cirrhosis.Methods:Ninety-seven cirrhosis patients with 109 small nodules(70 HCCs,39 benign nodules)of LR-3 and 4 LR-4 based on major and ancillary magnetic resonance imaging features were included.Multiparametric quantitative ADCs of the lesions,including the mean ADC(ADCmean),min-imum ADC(ADCmin),maximal ADC(ADCmax),ADC standard deviation(ADCstd),and mean ADC value ratio of lesion-to-liv-er parenchyma(ADCratio)were calculated.Regarding the joint diagnosis,a nomogram model was plotted using multivariate logistic regression analysis.The performance was assessed using the area under the receiver operating characteristic curve(AUC).Results:The ADCmean,ADCmin,ADCratio,and ADCstd were significantly associated with the identification of small HCC and benign nodules(pli-RADS category(odds ratio[OR]=12.50),ADCmin(OR=0.14),and ADCratio(OR=0.12)were identified as independent factors for distinguishing HCCs from benign nodules.The joint nomogram model showed good calibration and discrimination,with a C-index of 0.947.Compared with the li-RADS category alone,this nomogram model demon-strated a significant improvement in diagnostic performance,with AUC increasing from 0.820 to 0.967(p=0.001).Con-clusions:The addition of quantitative ADCs could improve the identification of small HCC and benign nodules catego-rized as LR-3 and 4 LR-4 in patients with cirrhosis.

On the backdrop of dwindling conventional reserves,unconventional reservoirs have emerged as a pivotal chapter in resource extraction.Despite their challenges,such as low permeability,complex fluid storage,and flow mechanisms,hydraulic fracturing technology has underpinned the development of unconventional reservoirs.Consequently,this has brought about a shift in the sequence of flow regimes,e.g.,the transient radial flow regime has been largely shortened by the lengthy transient linear flow regime due to the low permeability of unconventional reservoirs.Moreover,straight-line analysis(SLA),the simplest technique in rate transient analysis(RTA),is a fundamental and potent tool for swiftly extracting reservoir and hydraulic fracture information,estimating oil and gas reserves,and furnishing crucial initial data for subsequent historical matching processes.However,there is currently a dearth of review papers pertaining to a necessary guide of applying SLA in various transient linear flow(TLF)regimes and different unconventional reservoirs.Hence,this paper commences by elucidating the classification of TLF regimes,commonly used methods for recognizing flow regimes,and the diverse SLA methods used for different TLF regimes.Subsequently,it delves into a discussion of different modification techniques for variable rate/flowing pressure,gas phase,complex reservoir characteristics in unconventional reservoirs,and dynamic drainage area concepts etc.Furthermore,the application of SLA in specific domains,namely core analysis and the flowback period,is described.It culminates by surveying the advancements through an integration of novel technologies to enhance estimation accuracy.The paper also highlights certain drawbacks of current SLA technology and proposes new research directions.Ultimately,this paper would serve as an indispensable resource,offering foundational knowledge for the application of SLA in TLF to promote the production of global unconventional resources in a cost-effective and environmentally sustainable fa
