Fusarium ear rot(FER)caused by Fusarium verticillioides is one of the most common diseases affecting maize production *** results in severe yield losses and grain contamination with health-threatening *** most studies to date have focused on comprehensive analysis of gene regulation in maize during defense responses against *** infection,less is known about the role of micro RNAs(mi RNAs)in this *** used deep sequencing to compare small RNA libraries from the maize kernels of susceptible(N6)or resistant(BT-1)inbred lines from uninfected plants and upon *** *** found that pathogen exposure was accompanied by dynamic alterations in expression levels of multiple mi RNAs,including new members of previously annotated mi RNA families.A combination of transcriptomic,degradomic,and bioinformatics analyses revealed that ***-responsive mi RNAs and their potential target genes displayed opposite expression patterns in the susceptible and resistant *** category analysis uncovered preferential enrichment of the pathogen-responsive mi RNAs and their targets in the phenylpropanoid metabolic processes,plant–pathogen interactions,and plant phytohormone signal transduction ***,transgenic maize plants overexpressing mi R408 b exhibited reduced resistance to *** infection in a susceptible maize *** findings provide new insights into the regulatory roles of mi RNAs in maize immunity against FER and new resources for breeding disease resistance into maize.

A great amount of new S-wave data has been combined to image the mantle structure down to lower mantle depth near the southeastern margin of Eurasia and understand the tectonics in South China since the *** results reveal a large-scale structure beneath the South China Sea,with a prominent,broad low-velocity feature of at least 1500-km wide in and below the mantle transition zone(MTZ)and a pronounced low-velocity feature of nearly 500-km wide in the lowermost *** these features may represent the head-and-tail of an upwelling mantle plume that has interacted with and deformed by the subducting plates in the *** Andaman-Sumatra plate is seen subducting steeply without stagnation in the MTZ over the large-scale low-velocity structure,suggesting that the upwelling mantle may have exerted significant influence on the overlying plate *** results suggest a long-term extensional regime near the southeastern margin of Eurasia,which may help to understand the formation of the large-scale intra-plate magmatism and mineralization with accumulation of huge amount of rare metal elements in South China during the Mesozoic,and the continental breakup,the southeastward extrusion of Indochina,and the opening of the South China Sea during the Cenozoic.

为了满足窄带声表面波滤波器对品质因数Q值和带外抑制日益增长的需求,提出了一种窄带滤波器设计方法。在基于新型POI结构谐振器的基础上,通过旋转谐振器达到改变波传播角度的目的,并利用二维全模型得到准确的实验数据,与原结构谐振器分别代入滤波器设计中进行比较。实验结果表明,该方法在一定程度上能够有效地增加带外抑制,对过渡带抑制能力有2~4 dB的提升,且具有设计简便,占用空间小等优点。

Lithium(Li)penetration through solid electrolytes(SEs)induces short circuits in Li solid-state batteries(SSBs),which is a critical issue that hinders the development of high energy density *** cracking in ceramic SEs has been often shown to accompany Li penetration,the interplay between Li deposition and cracking remains ***,we constructed a mesoscale SSB inside a focused ion beam-scanning electron microscope(FIB-SEM)for in situ observation of Li deposition-induced cracking in SEs at nanometer *** results revealed that Li propagated predominantly along transgranular cracks in a garnet Li_(6.4)La_(3)Zr_(1.4)Ta_(0.6)O_(12)(LLZTO).Cracks appeared to initiate from the interior of LLZTO beneath the electrode surface and then propagated by curving toward the LLZTO *** resulting bowl-shaped cracks resemble those from hydraulic fracture caused by high fluid pressure on the surface of internal cracks,suggesting that the Li deposition-induced pressure is the major driving force of crack initiation and *** high pressure generated by Li deposition is further supported by in situ observation of the flow of filled Li between the crack flanks,causing crack widening and *** work unveils the dynamic interplay between Li deposition and cracking in SEs and provides insight into the mitigation of Li dendrite penetration in SSBs.

城市是企业创新活动的重要载体。基于异质企业集聚理论,利用制造业企业微观数据,构建托宾(Tobit)模型和中介效应检验的分析结果显示:城市规模对企业的新产品产值比例存在显著影响,城市规模增长促进本地企业创新,但邻近城市规模增长带来一定的抑制效应;具体作用机制包含竞争性孵化和包容性孵化两条路径,不同孵化机制对不同生产率企业的影响存在差异;市场的竞争选择主要作用于低效企业,而高效企业的创新更依赖于城市的中间服务支持。各地区应增强产业政策与城市发展的协同性、提升外部创新环境与企业内在特征的协同性、注重地区间城市化进程的协同性,充分发挥城市自身的市场竞争和中间服务对企业创新的推动作用,培育企业创新的内生动力。
