Li-rich manganese-based materials are considered to be the mainstream cathode materials for next-generation lithium-ion batteries due to high discharge capacity and low cost,but poor cycle life and high temperature performance limit their development.Herein,LiZr_(2)(PO_(4))_(3)(LZPO)is coated on the surface of spherical Li_(1.2)Mn_(0.54)Ni_(0.13)Co_(0.13)O_(2)(LMNCO)material by a simple wet chemical method.The LZPO layer not only has the function of traditional coating layer to inhibit the occurrence of side reactions between electrolyte and LMNCO surface but also promotes the formation of spinel phase in the layered structure,increases the content of lattice oxygen,and reduces the content of absorbed oxygen.Thus,LZPO coated LMNCO has a more stable layered structure during cycling compared pure LMNCO,which improves effectively its long life and high temperature performance.The capacity loss rate of LZPO coated LMNCO is only 16.2%and 11.9%after 350 cycles at 25℃and 200 cycles at 50℃,respectively.Moreover,the capacity retention rate of the full cell composed of LZPO coated LMNCO and graphite is 70.7%after 200 cycles at 1.0 C.The coating layer toward stable surface structure can provide an idea for the modification of cathode materials,especially for Li-rich manganese-based materials.

Heterosis contributes greatly to crop production, but the genetic basis of heterosis is not fully understood.To identify heterotic loci(HLs) for grain yield, 12 yield traits were evaluated in four rice(Oryza sativa L.)mapping populations: one parental population of chromosome segment substitution lines derived from a cross between the japonica cultivar Nipponbare and indica cultivar 9311 and three connected test populations in either a homozygous 9311 genetic background or a heterozygous background. A total of 390 HLs were detected for the measured traits in two environments. The genetic bases of heterosis differed between the backcross and testcross populations. At least 10 HLs were confirmed in F1 hybrids between9311 and near-isogenic lines, each of which carried a heterotic locus of interest in the same 9311 background. All 10 showed overdominant or dominant effects on grain yield and yield components. Among them, three were verified as being associated with yield heterosis and colocalized in the same regions as those containing previously reported heterosis-associated genes. Five HLs were identified to be promising candidate loci that could be used to achieve more than 15% yield heterosis in several commercial rice hybrids. These findings suggest the potential of indica or japonica introgression for increasing yield in hybrid rice breeding programs.

With marker and phenotype information from observed populations, genomic selection(GS) can be used to establish associations between markers and phenotypes. It aims to use genome-wide markers to estimate the effects of all loci and thereby predict the genetic values of untested populations, so as to achieve more comprehensive and reliable selection and to accelerate genetic progress in crop breeding. GS models usually face the problem that the number of markers is much higher than the number of phenotypic observations.To overcome this issue and improve prediction accuracy, many models and algorithms,including GBLUP, Bayes, and machine learning have been employed for GS. As hot issues in GS research, the estimation of non-additive genetic effects and the combined analysis of multiple traits or multiple environments are also important for improving the accuracy of prediction. In recent years, crop breeding has taken advantage of the development of GS.The principles and characteristics of current popular GS methods and research progress in these methods for crop improvement are reviewed in this paper.

The development of high-sulfur-loading Li-S batteries is a key prerequisite for their commercial applications.This requires to surmount the huge polarization,severe polysulfide shuttling and drastic volume change caused by electrode thickening.High-strength polar binders are ideal for constructing robust and long-life high-loading sulfur cathodes but show very weak interfacial interaction with non-polar sulfur materials.To address this issue,this work devises a highly integrated sulfur@polydopamine/highstrength binder composite cathodes,targeting long-lasting and high-sulfur-loading Li-S batteries.The super-adhesion polydopamine(PD)can form a uniform nano-coating over the graphene/sulfur(G-S)surface and provide strong affinity to the cross-linked polyacrylamide(c-PAM)binder,thus tightly integrating sulfur with the binder network and greatly boosting the overall mechanical strength/conductivity of the electrode.Moreover,the PD coating and c-PAM binder rich in polar groups can form two effective blockades against the effusion of soluble polysulfides.As such,the 4.5 mg cm−2 sulfur-loaded G-S@PD-c-PAM cathode achieves a capacity of 480 mAh g−1 after 300 cycles at 1 C,while maintaining a capacity of 396 mAh g−1 after 50 cycles at 0.2 C when the sulfur loading rises to 9.1 mg cm−2.This work provides a system-wide concept for constructing high-loading sulfur cathodes through integrated structural design.

Conversion-type reaction anode materials with high specific capacity are attractive candidates to improve lithium ion batteries(LIBs), yet the rapid capacity fading and poor rate capability caused by drastic volume change and low electronic conductivity greatly hinder their practical applications. To circumvent these issues, the successful design of yolk@shell Fe2 O3@C hybrid composed of a columnar-like Fe2O3 core within a hollow cavity completely surrounded by a thin, self-supported carbon(C) shell is presented as an anode for high-performance LIBs. This yolk@shell structure allows each Fe2O3 core to swell upon lithiation without deforming the carbon shell. This preserves the structural and electrical integrity against pulverization, as revealed by in situ transmission electron microscopy(TEM) measurement. Benefiting from these structural advantages, the resulting electrode exhibits a high reversible capacity(1013 m Ah g-1 after80 cycles at 0.2 A g-1), outstanding rate capability(710 m Ah g-1 at 8 A g-1) and superior cycling stability(800 m Ah g-1 after 300 cycles at 4 A g-1). A Li-ion full cell using prelithiated yolk@shell Fe2 O3@C hybrid as the anode and commercial Li CoO2(LCO) as the cathode demonstrates impressive cycling stability with a capacity retention of 84.5% after 100 cycles at 1 C rate, holding great promise for future practical applications.

Twenty-three isolates of soft rot bacteria from konjac corms were examined for their diversity using 16S rDNAs and AFLP technology. Both methods clustered two groups, dependent on their biotype characterization of Pectobacterium carotovora subsp. carotovora (P.c.c) and Pectobacterium chrysanthemi (P.ch), respectively. Of all isolates, 17 (73.9%) belonged to P. ch, indicated as the main pathogenic bacteria of konjac producing areas in China. The genetic variation among isolates from the same biotype was also rich, not consistent with the distances of the geographic sources.

Heterosis represents one of the most revolutionary advancements in crop improvement.In the genetic dissection of heterosis,NCIII design is one of the most powerful and widely used mating schemes.However,the methodologies for quantitative trait loci (QTL) detection in the design were mostly based on composite interval mapping.Therefore,in this study,our purpose was to develop a statistical method for mapping epistatic QTL associated with heterosis in the RIL-based NCIII design.First,we derivated the expectations of two classical linear transformations,Z 1 and Z 2,while a quantitative trait was controlled by two QTL with digenic epistasis and arbitrary linkage under the F ∞ and F 2 metric models.Then,we constructed an epistatic genetic model that includes all markers on the whole genome simultaneously,and estimated all the parameters in the model by the empirical Bayes approach.Finally,a series of Monte Carlo simulation experiments was carried out to confirm the proposed approach.The results show that:(1) all the augmented genetic parameters for main-effect QTL could be rightly identified with satisfactory statistical power and precision;(2) the statistical powers in the detection of augmented epistatic effects were substantively affected by the signs of pure epistatic effects;(3) it is more difficult to detect epistatic QTL than to detect main-effect QTL;(4) statistical power is higher in the RIL-based NCIII design than in the F 2-based NCIII design,especially in the detection of the augmented epistatic effect that consists of two pure epistatic effects in opposite directions.

水稻(Oryza sativa L.)是人类重要的粮食作物之一,由于杂交稻存在显性等非加性效应,稻米品质的遗传改良比常规稻更具挑战性。本研究基于113个自交系(父本)与5个测交系(母本),通过全基因组重测序,获得1619588个单核苷酸多态性位点(SNP)的基因型,并推断了565个杂交后代(113×5)的SNP基因型;对亲本自交系(V)和测交子代(T)的12个稻米品质性状进行表型测定,计算获得亲本的一般配合力(G)和测交子代的杂种优势(H),对V、T、G和H分别进行标准化,形成联合表型(Y),获得自交系(V)和测交子代(T)的加性基因型(A)和显性基因型(D),构建联合表型、加-显效应、多世代的表型代际效应分析流程(JPEG),共鉴定出128个位点与这些性状存在显著关联,其中加性效应、显性效应、同时含加性和显性效应的关联位点分别为44个、97个和13个。相比于传统的加性模型,JPEG实现了加-显效应同时分析的模型,不仅挖掘到更多稻米品质性状关联的加性和显性位点,且能分析加性、显性位点间的关系。研究结果表明测交子代稻米品质性状加-显性模型的遗传力远高于加性或显性模型的遗传力,说明非加性遗传效应是杂交稻稻米品质性状的重要遗传基础。进一步,基于加-显性位点的g BLUP全基因组预测方法对测交子代群体进行交叉独立预测,其预测精度远高于基于加性效应模型g BLUP法。且这些位点能解释测交子代每个性状表型中30%以上的总遗传变异(包括加性效应和显性效应)。JEPGpipeline(https://***/jiabowang/JPEG)可同时解析杂交稻的加性和显性遗传基础,进一步可发展为解析包含上位性等非加性效应等复杂遗传机理的分析流程,为优质杂交种选育提供帮助。

More and more studies demonstrate that a great deal of interactions among the quantitative trait loci (QTLs) are far more than those detected by single markers. A correlation method was proposed for estimating the interactions of multiple QTLs detected by multi-markers in several mapping populations. Genetic implication of this method and usage were discussed.
