| 1 | CH4/N2 separation on methane molecules grade diameter channel molecular sieves with a CHA-type structure显示文摘Samples of methane molecules grade diameter channel CHA-type molecular sieves(Chabazite-K, SAPO-34 and SSZ-13) were investigated using the adsorption separation of CH4/N2 mixtures. The isotherms recorded for CH4 and N2 follow a typical type-Ι behavior, which were fitted well with the Sips model(R2>0.999) and the selectivity was calculated using IAST theory. The results reveal that Chabazite-K has the highest selectivity(SCH4/N= 5.5).2 SSZ-13 has the largest capacity, which can adsorb up to a maximum of 30.957 cm3·g-1(STP) of CH4, due to it having the largest pore volume and surface area, but the lowest selectivity(SCH4/N2= 2.5). From the breakthrough test, we can conclude that SSZ-13 may be a suitable candidate for the recovery of CH4 from low concentration methane(CH4<20%) based on its larger pore volume and higher CH4 capacity. Chabazite-K is more suited to the separation of high concentration methane(CH4>50%) due to its higher selectivity. | Hua Shang Yuping Li Jiaqi Liu Xuan Tang Jiangfeng Yang Jinping Li | 2019 | Chinese Journal of Chemical Engineering2019，27，5： | 8 |
| 2 | Construction of a linkage map and QTL mapping for fiber quality traits in upland cotton (Gossypium hirsutum L.)显示文摘With the development in spinning technology, the improvement of cotton fiber quality is becoming more and more important. The main objective of this research was to construct a high-density genetic linkage map to facilitate marker assisted selection for fiber quality traits in upland cotton (Gossypium hirsutum L.). A genetic linkage map comprising 421 loci and covering 3814.3 cM, accounting for approximately 73.35% of the cotton genome, was constructed using an F2 population derived from cross GX1135 (P 1 )×GX100-2 (P 2 ). Forty-four of 49 linkage groups were assigned to the 26 chromosomes. Fiber quality traits were investigated in F2 population sampled from individuals, and in F2:3 , and F2:4 generations sampled by lines from two sites and one respectively, and each followed a randomized complete block design with two replications. Thirty-nine quantitative trait loci were detected for five fiber quality traits with data from single environments (separate analysis each): 12 for fiber length, five for fiber uniformity, nine for fiber strength, seven for fiber elongation, and six for fiber micronaire, whereas 15 QTLs were found in combined analysis (data from means of different environments in F2:3 generation). Among these QTLs, qFL-chr5-2 and qFL-chr14-2 for fiber length were detected simultaneously in three generations (four environments) and verified further by combined analysis, and these QTLs should be useful for marker assisted selection to improve fiber quality in upland cotton. | LIANG QingZhi HU Cheng HUA Hua LI ZhaoHu HUA JinPing | 2013 | Chinese Science Bulletin2013，58，26： | 7 |
| 3 | Designations for individual genomes and chromosomes in Gossypium显示文摘Gossypium, as the one of the biggest genera, the most diversity, and the highest economic value in field crops, is assuming an increasingly important role in studies on plant taxonomy, polyploidization, phylogeny, cytogenetics,and genomics. Here we update and provide a brief summary of the emerging picture of species relationships and diversification, and a set of the designations for individual genomes and chromosomes in Gossypium. This cytogenetic and genomic nomenclature will facilitate comparative studies worldwide, which range from basic taxonomic exploration to breeding and germplasm introgression. | WANG Kunbo WENDEL Jonathan F.

| 4 | Construction and initial analysis of five Fosmid libraries of mitochondrial genomes of cotton(Gossypium)显示文摘Cotton(Gossypium)is an important crop providing textile fiber and edible oil.To gain the insights into mechanism of the cytoplasmic male sterility(CMS)inheritance,we constructed five fosmid libraries of mitochondrial genomes from mitotype of G.harknessii Brandegee.(one CMS line and its restorer),mitotype of G.hirsutum L.(one CMS line and its maintainer),and G.barbadense L.The numbers of the clones in these libraries ranged from 1152 to 2016 with an average insert size of 36.2 to 38.4 kb,equivalent to 70–119.3 mitogenomes.The libraries were screened with 28 markers derived from the conservative sequences and yielded 22,19,26,21,and 23 positive clones,respectively.These positive clones were used to construct the physical map of G.harknessii Brandegee.CMS line and G.barbadense L.mitogenomes that shared six syntenis regions.A total of 30 genes in nine clusters showed conservative and had high similarity with those in the mitochondrial genomes of cotton,Carica papaya,Cucurbita pepo and Nicotiana tabacum.Further investigation indicated that gene rrn26 had two copies in all five cotton mitogenomes,while genes atp1,rrn5 and rrn18 had two copies only in G.barbadense L.The positive clones and physical map are considered being useful resources in cotton genomics research. | LI ShuangShuang LIU GuoZheng CHEN ZhiWen WANG YuMei LI PengBo HUA JinPing | 2013 | Chinese Science Bulletin2013，58，36： | 5 |

| 6 | QTL and genetic analysis controlling fiber quality traits using paternal backcross population in upland cotton显示文摘Background:Genetic improvement in fiber quality is one of the main challenges for cotton breeders.Quantitative trait loci(QTL)mapping provides a powerful approach to dissect the molecular mechanism in fiber quality traits.In present study,F14 recombinant inbred line(RIL)population was backcrossed to paternal parent for a paternal backcross(BC/P)population,deriving from one upland cotton hybrid.Three repetitive BC/P field trials and one maternal backcross(BC/M)field trial were performed including both two BC populations and the original RIL population.Results:In total,24 novel QTLs are detected for fiber quality traits and among which 13 QTLs validated previous results.Thirty-five QTLs in BC/P populations explain 5.01%–22.09%of phenotype variation(PV).Among the 35 QTLs,23 QTLs are detected in BC/P population alone.Present study provides novel alleles of male parent for fiber quality traits with positive genetic effects.Particularly,qFS-Chr3–1 explains 22.09%of PV in BC/P population,which increaseds 0.48 cN·tex−1 for fiber strength.A total of 7,2,8,2 and 6 QTLs explain over 10.00%of PV for fiber length,fiber uniformity,fiber strength,fiber elongation and fiber micronaire,respectively.In RIL population,six common QTLs are detected in more than one environment:qFL-Chr1–2,qFS-Chr5–1,qFS-Chr9–1,qFS-Chr21–1,qFM-Chr9–1 and qFM-Chr9–2.Two common QTLs of qFE-Chr2–2(TMB2386-SWU12343)and qFM-Chr9–1(NAU2873-CGR6771)explain 22.42%and 21.91%of PV.The region between NAU4034 and TMB1296 harbor 30 genes(379 kb)in A05 and 42 genes(49 kb)in D05 for fiber length along the QTL qFL-Chr5–1 in BC/P population,respectively.In addition,a total of 142 and 46 epistatic QTLs and QTL×environments(E-QTLs and QQEs)are identified in recombinant inbred lines in paternal backcross(RIL-P)and paternal backcross(BC/P)populations,respectively.Conclusions:The present studies provide informative basis for improving cotton fiber quality in different populations. | MA LingLing SU Ying NIE Hushuai CUI Yupeng CHENG Cheng IJAZ Babar HUA Jinping | 2020 | Journal of Cotton Research2020，3，3： | 3 |
| 7 | Prediction of VIGS efficiency by the Sfold program and its reliability analysis in Gossypium hirsutum显示文摘Genetic transformation in some plant species,including cotton(Gossypium hirsutum), is hampered by laborious and time-consuming processes and often unachievable. Virus-induced gene silencing(VIGS) by double-stranded RNAs can serve as a reverse-genetics tool to determine gene function. However, knockdown levels vary greatly when using a tobacco rattle virus-based vector that carries different c DNA fragments of a gene. How to choose the optional target fragment for high interference efficiency is very challenging. Addressing this challenge requires increasing the efficacy of small interference RNA(si RNA) in target fragment. Here, we describe a method to assess VIGS efficiency by comparing the following parameters of si RNA in target sequence: the disruption energy of the target(DGdisruption), the differential stability of si RNA duplex ends(DSSE), and the internal stability at positions 9–14 of the si RNA antisense strand(AIS), which are calculated by Sfold program(http://sfold.wadsworth.org). We find that the si RNAs with low DGdisruption, high DSSE and high AIS have high activity and easily result in high VIGS efficiency by experimentally testing the actual knockdown levels of the four target genes, Gh PDS,Gh CLA1, Gh AOS1, and Gh CXE1 via choosing different target sequences for each gene. Therefore, the Sfold program can be used to analyze target sequences when carrying out VIGS design to increase gene-silencing effects in plants. | Xiaoyang Ge Jie Wu Chaojun Zhang Qianhua Wang Yuxia Hou Zuoren Yang Zhaoen Yang Zhenzhen Xu Ye Wang Lili Lu Xueyan Zhang Jinping Hua Fuguang Li | 2016 | Science Bulletin2016，61，7： | 2 |

| 11 | Nitrogen rejection from low quality natural gas by pressure swing adsorption experiments and simulation using dynamic adsorption isotherms显示文摘In order to remove N_(2) from low quality natural gas,a mathematical model has been established by Aspen adsorption,using the CH_(4)-selective sorbent silicalite-1 pellets.The dynamic adsorption isotherm was first simulated by breakthrough simulation of a CH_(4)/N_(2) mixture at different adsorption pressures and feed flow rates based on breakthrough experiments.The resulting simulated CH_(4) dynamic adsorption amounts were very close to the experimental data at three different adsorption pressures(100,200,and 300 kPa).Moreover,a single-bed,three-step pressure swing adsorption(PSA)experiment was performed,and the results were in good agreement with the simulated data,further corroborating the accuracy of the gas dynamic adsorption isotherm obtained by the simulation method.Finally,based on the simulated dynamic adsorption isotherm of CH_(4) and N_(2),a four-bed,eight-step PSA process has been designed,which enriched 75%(vol)CH_(4) and 80%(vol)CH_(4) to 95%(vol)and 99%(vol),and provided 99%(vol)recovery. | Xinran Zhang Hua Shang Jiangfeng Yang Libo Li Jinping Li | 2022 | Chinese Journal of Chemical Engineering2022，35，2： | 1 |

| 13 | The morphological diversity of pollen in the genus Gossypium显示文摘Background Plant pollen has diverse morphological characteristics that can be consistently passed down from generation to generation.Information on pollen morphology is thus immensely important for plant classification and identification.In the genus Gossypium,however,in-depth research on pollen morphology is lacking,with only few reports on limited cotton species.To evaluate the diversity of pollen in Gossypium,we therefore conducted a comprehensive analysis of the pollen morphology of 33 cotton species and varieties using scanning electron microscopy.Results The 33 analyzed cotton samples exhibited common pollen morphological features,including spherical shapes,radial symmetry,echination,panporation,and operculation,while the pollen size,spine shape,spine density and length showed distinctive features.Pollen size varied significantly among species,with diameters ranging from62.43 μm in G.harknessii to 103.41 μm in G.barbadense.The exine had an echinate sculptural texture,and spines were mostly conical or sharply conical but occasionally rod-like.Spine density varied from 173 in G.incanum to 54 in G.gossypioides,while spine length ranged from 3.53 μm in G.herbaceum to 9.47 μm in G.barbadense.In addition,the 33cotton species and varieties were grouped at a genetic distance of 3.83 into three clusters.Cluster Ⅰ comprised five allotetraploid AD-genome cotton species,four D-genome species,and one K-genome species.Cluster Ⅱ included 13diploid species from A,B,D,E,and G genomes,whereas Cluster Ⅲ only consisted one E-genome species G.incanum.Conclusions Although pollen characteristics alone are not enough to resolve taxonomic and systematic relationships within the genus Gossypium,our results add to knowledge on palynomorphology and contribute to phenological information on these taxa.Our findings should aid future systematic and phylogenetic studies of the Gossypium genus. | CAI Xiaoyan HOU Yuqing MUHAMMAD Umer Jawad WANG Heng XU Yanchao ZHENG Jie WANG Yuhong LIU Fang ZHOU Zhongli HUA Jinping WANG Kunbo | 2023 | Journal of Cotton Research2023，6，1： | 0 |
