This study aimed to explore and improve the different economic values of Pinus koraiensis(Siebold and Zucc.)by examining the variations in 6 growth traits and 9 physicochemical wood properties among 53 P.koraiensis half-sib families.Growth traits assessed included height,diameter at breast height,volume,degree of stem straight-ness,stem form,and branch number per node,while wood properties assessed included density,fiber length and width,fiber length to width ratio,and cellulose,hemicel-lulose,holocellulose,lignin,and ash contents.Except for degree of stem straightness and branch number per node,all other traits exhibited highly significant variations(P<0.01)among families.The coefficients of variation ranged from 5.3(stem form)to 66.7%(ash content),whereas,the herit-ability ranged from 0.136(degree of stem straightness)to 0.962(ash content).Significant correlations were observed among growth traits and wood physicochemical properties.Principal component analysis identified four distinct groups representing growth traits,wood chemical and physical properties,and stem form traits.Multi-trait comprehensive evaluation identified three groups of elite families based on breeding objectives,including rapid growth,improved timber production for building and furniture materials,and pulpwood production.These specific families should be used to establish new plantations.

Owing to the complexity and variability of global climate,the study of extreme events to ensure food security is particularly critical.The standardized precipitation requirement index(SPRI)and chilling injury index(I_(Ci))were introduced using data from agrometeorological stations on the Songliao Plain between 1981 and 2020 to identify the spatial and temporal variability of drought,waterlogging,and low-temperature cold damage during various maize growth periods.Compound drought and low-temperature cold damage events(CDLEs)and compound waterlogging and low-temperature cold damage events(CWLEs)were then identified.To measure the intensity of compound events,the compound drought and low-temperature cold damage magnitude index(CDLMI),and compound waterlogging and low-temperature cold damage magnitude index(CWLMI)were constructed by fitting marginal distributions.Finally,the effects of extreme events of various intensities on maize output were examined.The findings demonstrate that:(1)There were significant differences in the temporal trends of the SPRI and ICiduring different maize growth periods.Drought predominated in the middle growth period(MP),waterlogging predominated in the early growth period(EP)and late growth period(LP),and both drought and waterlogging tended to increase in intensity and frequency.The frequency of low-temperature cold damage showed a decreasing trend in all periods.(2)The CDLMI and CWLMI can effectively determine the intensity of CDLEs and CWLEs in the study area;these CDLEs and CWLEs had higher intensity and frequency in the late growth period.(3)Compared to single events,maize relative meteorological yield had a more significant negative correlation with the CDLMI and CWLMI.

Phyton-International Journal of Experimental Botany 2022年第9期91卷 2055-2068页

To select elite materials,the growth traits of 32 Betula platyphylla clones at three separated northern sites in Northeast China were investigated and analyzed.The results showed that there were significant differences among all variation sources in the different investigated traits(P<0.01).Except for the carbon contents,all the coeffi-cients of phenotypic variation of the other investigated traits were higher than 10%.The repeatability of different traits ranged from 0.760 to 0.998.Correlation analysis showed that tree height were significantly correlated with diameter at breast height,but neither was significantly correlated with leaf traits nor element contents.Additive main effects and multiplicative interaction analysis showed that genotype,environment and genotype×environment interactions were significantly different in diameter at breast height,which indicated that environment had a significant effect on genotype.Comprehensive assessment results showed that three clones with high and stable diameters at breast height were selected,and the genetic gains of diameter at breast height on sites Maoershan,Qingan,and Yongji were 21.24%,20.58%,and 38.65%,respectively.The results could provide a theoretical basis for elite clone selection in B.platyphylla and other broad leaved species.

Introduction:Adaptation and mitigation are two main approaches to combating climate change.Mitigation is considered as the most important tasks in dealing with climate change in scientific res earch,financial support and technical practices as global warming intensifes;while currently the warming trend still cannot be reversed,and adaptation task seemed to gain urgency although it is late-starting.The synergies and tradeoffs of these two strategies revealed increasingly importance on reduding adverse dimate effects.Research on synergistic relationships has developed from definition and feasible analysis,to the development of quantitative tools and exploration in practice and application,though the latter aspect is still in its initial stage.Outcomes/other.Our review shows that the traits of mitigation and adaptation,the difer-ences and similarities between them,then ilustrate the significance and mechanism of their synergies and tradeoffs.And it is explained that methods and applications of single and integrated models,and cost-effectiveness analysis.Discussion/Conclusion:We hold the opinion that the future research and applications should be enhanced in terms of four aspects:reinforcement of interrelations and common mecha nisms between mitigation and adaptation actions study;building and improving the monitoring and evaluating systems;promoting departmental and regional scale investiga-tions and applications;and establishing policy and security systems.

基于意识形态建设的视角,中国共产党自我革命话语建构具有“三重面向”。面向党内的自我革命话语建构是要解决党的先进性和纯洁性问题,永葆党的先进性和生机活力,这是自我革命话语最根本的功能。面向党外与全社会的自我革命话语建构是要解决如何长期持续获得普遍的政治认同和获得人民拥护的问题。面向国际社会的自我革命话语建构,有助于提升中国共产党国际形象、丰富和发展中国特色社会主义话语体系与提升国际话语权。自我革命话语要根据不同的面向采取不同的话语叙事方式与策略。

Cloning and Functional Characterization of Chalcone Isomerase Genes Involved in Anthocyanin Biosynthesis in Clivia miniata

Chalcone isomerase(CHI),catalyzing isomerization of chalcones,is a crucial enzyme in flavonoid biosynthesis.Three CHI genes were isolated from Clivia miniata and designated as CmCHI1,CmCHI2 and CmCHI3,respectively.Multiple sequence alignments and phylogenetic analysis showed that CmCHI1 and CmCHI2 were members of type I CHI proteins,whereas CmCHI3 belonged to type IV CHI proteins.Subcellular localization analysis found that all three CmCHIs had diffused distribution in the cytoplasm similar to green fluorescent protein(GFP).Anthocyanin biosynthesis and gene expression analysis demonstrated that CmCHIs were highly expressed in anthocyanin accumulated tissues.To further functionally characterize the role of CmCHIs,an in vitro enzymatic activity assay was carried out using the purified recombinant proteins.Results showed that CmCHI1 and CmCHI2 could completely convert the substrate naringenin chalcone(NC)into the product naringenin(NA),whereas CmCHI3 seemed nonfunctional as no increment of NA was detected.Further genetic transformation of Arabidopsis tt5-1 mutant validated that CmCHI1 and CmCHI2 rather than CmCHI3 could complement the chi deficient phenotypes.In summary,CmCHI1 and CmCHI2 are the real active CHI genes in Clivia miniata.The results not only broaden our knowledge on flavonoid biosynthesis in C.miniata but also lay a new foundation for further flavonoid modification in C.miniata.

装配式建筑作为建筑业生产方式转型升级的一项重大变革,以其节能、环保、高效、安全等优点备受瞩目,然而,由于相关技术尚不成熟,开发成本较高,大多数公众对其缺乏了解而不愿意购买,这成为了装配式建筑发展的一大障碍。因此有必要从参与主体的角度出发,对装配式建筑激励机制进行深入研究,以期为其推广提供有效借鉴。笔者以某装配式建筑项目为例,首先对该项目的参与主体进行界定和行为分析,其次运用演化博弈方法建立政府、开发商和消费者三方博弈模型,深入分析某装配式建筑项目博弈主体策略的演化过程,探讨关键参数对演化结果的影响,最后提出一系列合理的对策及建议。

吉林省作为我国玉米主产区和重要的商品粮基地,明确吉林省玉米水分盈亏指数及旱涝灾害的时空分布特征,有助于提高农业生产的稳定性和抗灾能力。该文采用吉林省逐日气象站点数据,通过计算月尺度下的潜在蒸散量,构建水分盈亏指数来分析吉林省潜在蒸散量和旱涝灾害的时空分布特征,运用趋势分析法和小波分析法来探究水分盈亏指数的趋势性及周期性变化。结果表明:多年平均潜在蒸散量和各月份平均潜在蒸散量均有由西北至东南逐渐递减的趋势,5—9月潜在蒸散量分别占生长周期内总平均潜在蒸散量的26.3%、24.5%、21.1%、16.8%和11.3%。5月和9月发生中旱及以上频率大于50%的地区主要位于白城市西部,四平市西部和长春市中部地区。8月和9月中涝及以上频率高值区位于吉林省东部及东南部地区。
