Sesame Fusarium wilt(SFW),caused by Fusarium oxysporum f.***.sesami(Fos),is one of the most devastating diseases affecting sesame cultivation.Deciphering the genetic control of SFW resistance is pivotal for effective disease management in sesame.An inheritance study on a cross between the highly resistant variety Yuzhi 11 and the highly susceptible accession Sp1 using a Fos pathogenicity group 1 isolate indicated that resistance was conferred by a single dominant allele.The target locus was located in a 1.24 Mb interval on chromosome 3 using a combination of cross-population association mapping and bulked segregant analysis.Fine genetic mapping further narrowed the interval between 21,350 and 21,401 kb.The locus Sindi_0812400 was identified as the SFW resistance gene and officially designated SiRLK1.This gene encodes a specific malectin/receptor-like protein kinase with three putative tandem kinase domains and is considered a kinase fusion protein.Sequence analysis revealed that a high proportion(49.44%)of variants within the locus was located within the kinase domainⅢ,and several of which were evidently associated with the diversity in SFW response,indicating the critical role of kinase domainⅢin expression of disease resistance.These findings provide valuable information for further functional analysis of SFW resistance genes and marker-assisted resistance breeding in sesame.

High-entropy oxides(HEOs)have received significant attention because of their tunable mechanical properties and wide range of functional applications.However,the conventional method used for sintering HEOs requires prolonged processing time,which results in excessive grain growth,thereby compromising their performance.Here,an ultrafast high-temperature sintering(UHS)strategy was adopted,and rock-salt composite(Mg_(0.2)Co_(0.2)Ni_(0.2)Cu_(0.2)Zn_(0.2))O was selected as model materials.Experimental parameters were tuned to illustrate the influence of applied current and soaking time on the densification process and resulting grain size.Additionally,the electrochemical performance of UHS-synthesized microparticles as anode materials in lithium-ion batteries was investigated.The results show that the ultrafast heating rate results in fine grains with a diameter of~6–8μm and density of 95%,which are much smaller and similar to those obtained using the conventional sintering method(25μm and 96%).Moreover,the high surface area and reactivity of the microparticles,as well as their sluggish diffusion effect and structural stability,contribute to outstanding performance with high capacity(336 ma·h/g at 1 A/g)and ultralong cyclability(1000 cycles).This novel technique offers valuable insights into the densification process of HEOs and other materials and can thus broaden their application range.

Single-phase Ba(Ti_(0.2)Zr_(0.2)Sn_(0.2)Hf_(0.2)Ce_(0.2))O_(3)(BTZSHC) high-entropy ceramics(HECs) with the perovskite structure were successfully prepared via the sol-gel method.The results reveal that the as-prepared ceramics exhibit a single cubic phase belonging to the Pm3 m space group.The high entropy is the driving force of the formation of single-phase ceramics.A larger entropy(ΔS_(mix)) and a negative enthalpy(ΔH_(mix)) are conducive to the formation of single-phase compounds.Herein,ΔS_(mix)=0.323 R mole-1andΔH_(mix)=43.88 kJ/mol.The sluggish-diffusion effect ensures the thermal stability of high-entropy systems.Dielectric measurements reveal that the as-prepared BTZSHC high-entropy ceramics are relaxor ferroelectrics,and the degree of relaxor(γ) is 1.9.The relaxor behavior of the as-prepared ceramics can be ascribed to the relaxation and thermal evolution of their polar units(PUs).The findings of this work provide a theoretical basis and technical support for the preparation of single-phase high-entropy ceramics.

针对高速铁路桥梁新旧线并行修建引起的横桥向墩台不均匀沉降的问题,利用ABAQUS有限元分析方法,选取高速铁路常用的32 m标准双线多跨简支梁桥,建立CRTSⅢ型单元板式无砟轨道-桥梁-墩台空间静力耦合模型;考虑不同沉降类型和沉降幅值,研究横桥向桥墩不均匀沉降对轨道结构层间受力及其轨面变形规律,在此基础上提出适用于该桥型的单、双墩横桥向不均匀沉降静态损伤分级及维修建议。结果表明:横桥向墩台不均匀沉降对轨面高低不平顺影响最大,其次为扭曲和水平不平顺,且沉降墩顶处易出现变形极值;横桥向墩台仅单侧沉降时,单墩沉降差10、15、20 mm,伤损等级依次为Ⅱ、Ⅲ、Ⅳ级;需要关注桥墩横桥向双侧沉降情形,损伤比单侧沉降更严重;当沉降差达到20 mm时,自密实混凝土层横向拉应力超过C40混凝土抗拉强度限值,轨道结构存在开裂风险。建议日常保养时单、双墩横桥向不均匀沉降控制在10 mm及以下,应避免出现沉降15 mm及以上的不利情形。

The nucleation of eutectic crystals of hypoeutectic A1-7 wt pct Si-Mg casting alloys modified by Ce and Sr was studied by using differential scanning calorimeter （DSC） and scanning electron microscope （SEM）. DSC results were applied to calculate the values of activity energy and nucleation work of eutectic nucleation for the alloys. These values were decreased and the eutectic nucleation frequency was increased with the addition of Ce and Sr to the alloys. Moreover, the morphology of eutectic silicon in the modified alloys was partially or fully modified as fine, fibrous or coral, and DSC plots show that the eutectic undercooling of A1-7 wt pct Si-Mg alloys were increased with additions of modified agents. The mechanism of eutectic modification is combined actions of the accelerated nucleation and the restricted growth.

Rare Metals 2012年第4期31卷 332-335页

The effect of single addition of La or Sm on the microstructures and mechanical properties of an Al-Cu-Mn alloy were investigated by microstructure characterization and tensile test. The results show that addition of La or Sm into the Al-Cu-Mn alloy can remarkably increase the density of θ′ phase and refine the microstructure, and thus, improves the mechanical properties at room temperature. La addition results in a more considerable increase in the density and refinement of θ′ phase than Sm addition. La addition has a more significant contribution on the mechanical properties of the Al-Cu-Mn alloy than Sm addition. In addition, a new phase of Al6Cu6La is formed in the Al-Cu-Mn alloy with La addition.

Pedosphere 2017年第3期27卷 537-547页

Persistent organic pollutants(POPs) in soils are an environmental concern due to their long-term bioavailability, which could be reduced by adding adsorbents. However, testing of these adsorbents is necessary prior to widespread field application. The effects of three adsorbents, nano-organic montmorillonite, nano-organic silicon dioxide(SiO_2), and activated carbon, on hexachlorobenzene(HCB) and pentachlorobenzene(Pe CB) accumulation in rice(Oryza sativa L.) plants were tested in a greenhouse experiment using two soils, a Hydragric Acrisol(Ac) and a Gleyi-Stagnic Anthrosol(An). The bioconcentration factors(BCFs) of HCB and Pe CB to rice roots were 2.3–3.7 and 2.0–3.0 times those to rice shoots, respectively. The applications of the three adsorbents decreased HCB and Pe CB extractability in Ac, while only the application of activated carbon decreased their extractability in An. The bioavailability of HCB and Pe CB to rice plants in Ac was higher than that in An. In Ac, the applications of nano-organic SiO_2 and activated carbon decreased the BCF of HCB to rice roots by 16.1% and 26.8%, respectively, whereas only the application of activated carbon decreased the BCF of Pe CB to rice roots by 31.4%, compared to the control. In An, only the application of activated carbon decreased the BCFs of HCB and Pe CB to rice roots by 22.9% and 18.2%, respectively, compared to the control. However, the application of nano-organic montmorillonite inhibited rice growth in both soils. The results of this study suggested that the effectiveness of adsorbents would vary with pollutant and soil types, providing a reference point for developing efficient adsorbents to reduce the ecological risk of POPs.

The red flesh in apple fruit is a desired trait by consumers and it is associated to the anthocyanin content,which is mainly controlled by MdMYB10 with a R6 promoter.In this study,a high-density linkage group was constructed using the‘Fuji’x‘Red3’population which contained homozygous alleles R1R1 and R6R6,respectively.The linkage group consists of 7630 SNPs along 17 linkage groups,spanning 2270.21 cM,with an average density of 0.30 cM permarker.The cyanidin-3-galactoside concentration was used as the phenotypic data in QTL analysis.Moreover,one QTL peak which was flaked by two markers,marker2187260 to marker2173766,with LOD scores of 4.49 was detected.This QTL ranged from 0 to 40.79 cM on the top of linkage group(LG16).In addition one candidate molecular marker(marker2175442)in this QTL was identified,which was significant correlated with the flesh cyanidin-3-galactoside concentration.These genetic findings enrich the breeding basis of fruit flesh coloration in apple.
