1Diversity characterization and association analysis of agronomic traits in a Chinese peanut (Arachis hypogaea L.) mini-core collection显示文摘Association mapping is a powerful approach for exploring the molecular basis of phenotypic variations in plants.A peanut(Arachis hypogaea L.)mini-core collection in China comprising 298 accessions was genotyped using 109 simple sequence repeat(SSR)markers,which identified 554 SSR alleles and phenotyped for 15 agronomic traits in three different environments,exhibiting abundant genetic and phenotypic diversity within the panel.A model-based structure analysis assigned all accessions to three groups.Most of the accessions had the relative kinship of less than 0.05,indicating that there were no or weak relationships between accessions of the mini-core collection.For 15 agronomic traits in the peanut panel,generally the Q t K model exhibited the best performance to eliminate the false associated positives compared to the Q model and the general linear model-simple model.In total,89SSR alleles were identified to be associated with 15 agronomic traits of three environments by the Q t K model-based association analysis.Of these,eight alleles were repeatedly detected in two or three environments,and 15 alleles were commonly detected to be associated with multiple agronomic traits.Simple sequence repeat allelic effects confirmed significant differences between different genotypes of these repeatedly detected markers.Our results demonstrate the great potential of integrating the association analysis and marker-assisted breeding by utilizing the peanut mini-core collection.Huifang Jiang Li Huang Xiaoping Ren Yuning Chen Xiaojing Zhou Youlin Xia Jiaquan Huang Yong Lei Liying Yan Liyun Wan Boshou Liao 2014Journal of Integrative Plant Biology2014,56,2:14
2Single-cell transcriptome analysis of the novel coronavirus (SARS-CoV-2) associated gene ACE2 expression in normal and non-obstructive azoospermia (NOA) human male testes显示文摘Being infected by SARS-CoV-2 may cause damage to multiple organs in patients, such as the lung, liver and heart. Angiotensin-converting enzyme 2(ACE2), reported as a SARS-CoV-2 receptor, is also expressed in human male testes. This suggests a potential risk in human male reproductive system. However, the characteristics of ACE2-positive cells and the expression of other SARS-CoV-2 process-related genes are still worthy of further investigation. Here, we performed singlecell RNA seq(scRNA-seq) analysis on 853 male embryo primordial germ cells(PGCs) and 2,854 normal testis cells to assess the effects of the SARS-CoV-2 virus on the male reproductive system from embryonic stage to adulthood. We also collected and constructed the scRNA-seq library on 228 Sertoli cells from three non-obstructive azoospermia(NOA) patients to assess the effects at disease state. We found that ACE2 expressing cells existed in almost all testis cell types and Sertoli cells had highest expression level and positive cells ratio. Moreover, ACE2 was also expressed in human male PGCs. In adulthood, the level of ACE2 expression decreased with the increase of age. We also found that ACE2 positive cells had high expressions of stress response and immune activation-related genes. Interestingly, some potential SARS-CoV-2 process-related genes such as TMPRSS2, BSG, CTSL and CTSB had different expression patterns in the same cell type. Furthermore, ACE2 expression level in NOA donors’ Sertoli cells was significantly decreased. Our work would help to assess the risk of SARS-CoV-2 infection in the male reproductive system.Xixi Liu Yidong Chen Wenhao Tang Li Zhang Wei Chen Zhiqiang Yan Peng Yuan Ming Yang Siming Kong Liying Yan Jie Qiao 2020Science China(Life Sciences)2020,63,7:14

4DNA methylation and chromatin accessibility profiling of mouse and human fetal germ cells显示文摘染色质改变为人的初发的细菌房间的 epigenetic reprogramming 是重要的。然而,全面染色质状态还没为人的胎儿的细菌房间(FGC ) 被分析了。这里,我们使用 nucleosome 占有和 methylation 定序方法在人和老鼠在胎儿的细菌房间开发期间在一系列关键时间点分析染色体宽的染色质可接近性和 DNA methylome。我们在人和老鼠 FGC 发现 116 887 和 137 557 个弄空 nucleosome 的区域(NDR ) ,盖住 germline 特定、高度有活力的规章的 genomic 元素的一个大集合,例如 enhancers。而且,我们发现远侧的 NDR 在人的 FGC 为象 NANOG , SOX17 , AP2 和 OCT4 那样的 pluripotency 和细菌房间主人管理者的有约束力的主题明确地被充实,显示在pluripotency相关的基因和细菌之间的精细的规章的平衡的存在在人的 FGC 的房间特定的基因,并且为在 vivo 的细菌房间开发的这些基因的功能的意义。我们的工作为把提供一张全面、高分辨率的路线图染色质状态转变动力学在人和老鼠 FGC 的 epigenomic reprogramming 期间。Hongshan Guo Boqiang Hu Liying Yan Jun Yong Yan Wu Yun Gao Fan Guo Yu Hou Xiaoying Fan Ji Dong Xiaoye Wang Xiaohui Zhu Jie Yan Yuan Wei Hongyan Jin Wenxin Zhang Lu Wen FuchouTang Jie Qiao 2017Cell Research2017,27,2:9
5WIP1 Phosphatase Plays a Critical Neuroprotective Role in Brain Injury Induced by High-Altitude Hypoxic Inflammation显示文摘The hypobaric hypoxic environment in highaltitude areas often aggravates the severity of inflammation and induces brain injury as a consequence. However, the critical genes regulating this process remain largely unknown. The phosphatase wild-type p53-induced phosphatase 1(WIP1) plays important roles in various physiological and pathological processes, including the regulation of inflammation in normoxia, but its functions in hypoxic inflammation-induced brain injury remain unclear.Here, we established a mouse model of this type of injury and found that WIP1 deficiency augmented the release of inflammatory cytokines in the peripheral circulation and brain tissue, increased the numbers of activated microglia/macrophages in the brain, aggravated cerebral histological lesions, and exacerbated the impairment of motor and cognitive abilities. Collectively, these results provide the first in vivo evidence that WIP1 is a critical neuroprotector against hypoxic inflammation-induced brain injury.Dahu Li Lijun Zhang Xin Huang Lili Liu Yunling He Lun Xu Yiyao Zhang Tong Zhao Liying Wu Yongqi Zhao Kuiwu Wu Yan Wu Ming Fan Lingling Zhu 2017Neuroscience Bulletin2017,33,3:9
6Clinical applications of MARSALA for preimplantation genetic diagnosis of spinal muscular atrophy显示文摘Conventional PCR methods combined with linkage analysis based on short tandem repeats(STRs) or Karyomapping with single nucleotide polymorphism(SNP) arrays, have been applied to preimplantation genetic diagnosis(PGD) for spinal muscular atrophy(SMA), an autosome recessive disorder. However, it has limitations in SMA diagnosis by Karyomapping, and these methods are unable to distinguish wildtype embryos with carriers effectively. Mutated allele revealed by sequencing with aneuploidy and linkage analyses(MARSALA) is a new method allowing embryo selection by a one-step next-generation sequencing(NGS) procedure, which has been applied in PGD for both autosome dominant and X-linked diseases in our group previously. In this study, we carried out PGD based on MARSALA for two carrier families with SMA affected children. As a result, one of the couples has given birth to a healthy baby free of mutations in SMA-causing gene. It is the first time that MARSALA was applied to PGD for SMA, and we can distinguish the embryos with heterozygous deletion(carriers) from the wild-type(normal) ones accurately through this NGS-based method. In addition, direct mutation detection allows us to identify the affected embryos(homozygous deletion), which can be regarded as probands for linkage analysis, in case that the affected family member is absent. In the future, the NGS-based MARSALA method is expected to be used in PGD for all monogenetic disorders with known pathogenic gene mutation.Yixin Ren Xu Zhi Xiaohui Zhu Jin Huang Ying Lian Rong Li Hongyan Jin Yan Zhang Wenxin Zhang Yanli Nie Yuan Wei Zhaohui Liu Donghong Song Ping Liu Jie Qiao Liying Yan 2016Journal of Genetics and Genomics2016,43,9:9
7Effect of Gold Nanoparticles on the Photocatalytic and Photoelectrochemical Performance of Au Modified BiVO_4显示文摘An efficient visible light driven photocatalyst, gold nanoparticles(NPs) modified Bi VO_4(Au/Bi VO_4), has been synthesized by deposition-precipitation with urea method. Au/Bi VO_4 exhibits enhanced photocatalytic activity for phenol degradation underλ>400 nm irradiation but negligible activity underλ>535 nm,indicating that the surface plasmon resonance(SPR) effect is too weak for organic photodegradation. According to the photoelectrochemical results of the porous powder electrodes of Bi VO_4 and Au/Bi VO_4, the SPR effect of Au NPs has been assessed. The role of Au NPs as electron sinks or sources, which is controllable by incident photon energy and applied potentials, has been discussed.Mingce Long Jingjing Jiang Yan Li Ruqiong Cao Liying Zhang Weimin Cai 2011Nano-Micro Letters2011,3,3:8
8Salivary mycobiome dysbiosis and its potential impact on bacteriome shifts and host immunity in oral lichen planus显示文摘The biodiversity of the mycobiome,an important component of the oral microbial community,and the roles of fungal–bacterial and fungal–immune system interactions in the pathogenesis of oral lichen planus (OLP) remain largely uncharacterized.In this study,we sequenced the salivary mycobiome and bacteriome associated with OLP.First,we described the dysbiosis of the microbiome in OLP patients,which exhibits lower levels of fungi and higher levels of bacteria.Significantly higher abundances of the fungi Candida and Aspergillus in patients with reticular OLP and of Alternaria and Sclerotiniaceae_unidentified in patients with erosive OLP were observed compared to the healthy controls.Aspergillus was identified as an “OLP-associated” fungus because of its detection at a higher frequency than in the healthy controls.Second,the co-occurrence patterns of the salivary mycobiome–bacteriome demonstrated negative associations between specific fungal and bacterial taxa identified in the healthy controls,which diminished in the reticular OLP group and even became positive in the erosive OLP group.Moreover,the oral cavities of OLP patients were colonized by dysbiotic oral flora with lower ecological network complexity and decreased fungal–Firmicutes and increased fungal–Bacteroidetes sub-networks.Third,several keystone fungal genera (Bovista,Erysiphe,Psathyrella,etc.) demonstrated significant correlations with clinical scores and IL-17 levels.Thus,we established that fungal dysbiosis is associated with the aggravation of OLP.Fungal dysbiosis could alter the salivary bacteriome or may reflect a direct effect of host immunity,which participates in OLP pathogenesis.Yan Li Kun Wang Bo Zhang Qichao Tu Yufei Yao Bomiao Cui Biao Ren Jinzhi He Xin Shen Joy D.Van Nostrand Jizhong Zhou Wenyuan Shi Liying Xiao Changqing Lu Xuedong Zhou 2019International Journal of Oral Science2019,11,3:8
9The present and future of whole-exome sequencing in studying andtreating human reproductive disorders显示文摘The causes of recurrent spontaneous abortion (RSA) and fetal malformations are multifactorial and unclear in most cases. Environmental, maternal, and genetic factors have been shown to contribute to these defects. Whole-exome sequencing (WES) is widely used to detect genetic variations associated with human diseases and has recently been successfully applied to unveil genetic causes of unexplained recurrent spontaneous abortion (URSA) and fetal malformations. Here, we review the current discovery and diagnosis strategies to identify the underlying pathogenic mutations of URSA and fetal malformations using WES technology and propose to further develop WES, both to advance our understanding of these diseases and to eventually lead to targeted therapies for reproductive disorders.Wei Guo Xiaohui Zhu Liying Yan Jie Qiao 2018Journal of Genetics and Genomics2018,45,10:6
10Three‑Dimensional Ordered Mesoporous Carbon Spheres Modified with Ultrafine Zinc Oxide Nanoparticles for Enhanced Microwave Absorption Properties显示文摘Currently,electromagnetic radiation and interference have a significant effect on the operation of electronic devices and human health systems.Thus,developing excellent microwave absorbers have a huge significance in the material research field.Herein,a kind of ultrafine zinc oxide(ZnO)nanoparticles(NPs)supported on three-dimensional(3D)ordered mesoporous carbon spheres(ZnO/OMCS)is prepared from silica inverse opal by using phenolic resol precursor as carbon source.The prepared lightweight ZnO/OMCS nanocomposites exhibit 3D ordered carbon sphere array and highly dispersed ultrafine ZnO NPs on the mesoporous cell walls of carbon spheres.ZnO/OMCS-30 shows microwave absorbing ability with a strong absorption(−39.3 dB at 10.4 GHz with a small thickness of 2 mm)and a broad effective absorption bandwidth(9.1 GHz).The outstanding microwave absorbing ability benefits to the well-dispersed ultrafine ZnO NPs and the 3D ordered mesoporous carbon spheres structure.This work opened up a unique way for developing lightweight and high-efficient carbon-based microwave absorbing materials.Yan Song Fuxing Yin Chengwei Zhang Weibing Guo Liying Han Ye Yuan 2021Nano-Micro Letters2021,13,5:6
11Effects of vitrification and cryostorage duration on single-cell RNA-Seq profiling of vitrified-thawed human metaphase Ⅱ oocytes显示文摘Oocyte cryopreservation is widely used for clinical and social reasons.Previous studies have demonstrated that conventional slow-freezing cryopreservation procedures,but not storage time,can alter the gene expression profiles of frozen oocytes.Whether vitrification procedures and the related frozen storage durations have any effects on the transcriptomes of human metaphase Ⅱ oocytes remain unknown.Four women(30–32 years old)who had undergone IVF treatment were recruited for this study.RNA-Seq profiles of 3 fresh oocytes and 13 surviving vitrified-thawed oocytes(3,3,4,and 3 oocytes were cryostored for 1,2,3,and 12 months)were analyzed at a single-cell resolution.A total of 1987 genes were differentially expressed in the 13 vitrifiedthawed oocytes.However,no differentially expressed genes were found between any two groups among the 1-,2-,3-,and 12-month storage groups.Further analysis revealed that the aberrant genes in the vitrified oocytes were closely related to oogenesis and development.Our findings indicated that the effects of vitrification on the transcriptomes of mature human oocytes are induced by the procedure itself,suggesting that long-term cryostorage of human oocytes is safe.Ying Huo Peng Yuan Qingyuan Qin Zhiqiang Yan Liying Yan Ping Liu Rong Li Jie Yan Jie Qiao 2021Frontiers of Medicine2021,15,1:6
12Genetic analysis and preimplantation genetic diagnosis of Chinese Marfan syndrome patients显示文摘Marfan syndrome (MFS)(OMIM 154700) is a relatively common autosomal dominant genetic disease that causes skeletal, ocular, and cardiovascular defects and was first described by a French pediatrician in 1896 (Bitterman and Sponseller, 2017). Its prevalence rate is 1/3000—1/5000, and more than 25% of cases are sporadic (Chiu et al., 2014). Studies have shown that about 90% of MFS is caused by variants in the fibrillin-1 gene (FBN1, OMIM 134797). FBN1, located on chromosome 15q21.1, encodes a macromolecular glycoprotein-fibrin 1, which aggregates to form microfibers in the extracellular matrix and distributes in various human connective tissues, such as periosteum, vessel wall, and crystal suspensor ligament. Variants in FNB1 have been reported in 65 exons, but the relationship between genotype and phenotype remains rather unclear (Sakai et al., 2016). Studies have also shown that patients with MFS and similar diseases may have variants in other related genes such as members of the transforming growth factor beta receptor (TGFBR) family (Mizuguchi et al., 2004;Sakai et al., 2006;Bolar et al., 2012;De Cario et al., 2018). For better prevention and treatment of MFS as well as for suspected MFS patients, there is a strong need for efficient genetic testing for early diagnosis and differential diagnoses of patients with related phenotypes (Aubart et al., 2018).Meng Qin Xiaohui Zhu Zhe Zhang Xuemin Li Zhiqiang Yan Yuqian Wang Shuo Guan Yihua He Wenxin Zhang Liying Yan Jie Qiao Xu Zhi 2019Journal of Genetics and Genomics2019,46,6:6
13First-principles study on electronic structure and optical properties of N-doped P-type β-Ga_2O_3显示文摘The band structure, density of states, electron density difference and optical properties of intrinsic β-Ga2O3 and N-doped β-Ga2O3 were calculated using first-principles based on density functional theory. After N doping, the band gap decreases, shallow acceptor impurity levels are introduced over the top of the valence band and the absorption band edge is slightly red-shifted compared to that of the intrinsic one. The anisotropic optical properties are investigated by means of the complex dielectric function, which are explained by the selection rule of the band-to-band transitions. All calculation results indicate that N-doping is a very promising method to get P-type β-Ga2O3.ZHANG LiYing YAN JinLiang ZHANG YiJun LI Ting DING XingWei 2012Science China(Physics,Mechanics & Astronomy)2012,55,1:5
14Impact of biochar amendment on soil aggregation varied with incubation duration and biochar pyrolysis temperature显示文摘Soil aggregation is one of the crucial processes that facilitate carbon sequestration and maintain soil fertility.So far,the effect of biochar amendment on soil aggregation remains inconclusive.Here,we tested the hypothesis that the response of soil aggregation to biochar addition varied with incubation duration and biochar chemistry.A one year microcosm experiment of soil with biochar was conducted that included biochar produced at three different temperatures(300,450,and 600°C),and three biochar application rates,i.e.,0,1,and 3 wt%.It was observed that after one and three months,biochar mainly(>90%)distributed in the micro-aggregates,and slightly reduced aggregate stability and increased proportion of micro-aggregates,which was demonstrated to result from the mechanical mixture of amended biochar with soil.Contrastingly,when the duration was prolonged to six months and one year,a significant increase in macro-aggregates(6.6-38.5%)and aggregate stability(7.3-29.4%)was detected,with the increasing extent being apparently higher for low-temperature biochar.This was related to the comparatively strong interaction of biochar particles with soil minerals or microbes after long-time incubation.The strong interaction was directly supported by the significant increase in H/C,O/C ratios of isolated biochar from treated soils,the detection of typical soil mineral elements on the surface of isolated biochar,and the increase in microbial biomass carbon of treated soils.The findings of this study highlighted the role of biochar type and amendment duration in mediating the effect of biochar application on soil aggregation.Lanfang Han Biao Zhang Liying Chen Yanfang Feng Yan Yang Ke Sun 2021Biochar2021,3,3:4
15Genetic testing and PGD for unexplained recurrent fetal malformations with MAGEL2 gene mutation显示文摘Birth defects are caused by multiple factors,such as chromosome abnormality,environmental factors,and maternal factors.In this study,we focused on exploring the genetic causes of a non-consanguineous couple who suffered from four times of unsuccessful pregnancy due to unexplained recurrent fetal malformations with similar symptoms and normal chromosome copy number variations.Using trio-whole exome sequencing(trio-WES) for this couple and one of the affected fetuses,we found a mutation,c.1996 delC on the maternal imprinted gene MAGEL2 that was carried by the affected fetus and husband,leading to Schaaf-Yang syndrome.To screen this mutation,we further performed preimplantation genetic diagnosis(PGD) strategy followed by a gene pedigree validation and pathogenicity analysis.After the transfer of a PGD-screened embryo,a normal newborn without previous abnormal symptoms was born(February 15,2019).We present the first data that identified a pathogenic gene(MAGEL2 c.1996 delC) in a fetus with Schaaf-Yang syndrome in the EAS(East Asian) database and overcame this genetic defect by using processed PGD for this couple based on the WES results.Wei Guo Yanli Nie Zhiqiang Yan Xiaohui Zhu Yuqian Wang Shuo Guan Ying Kuo Wenxin Zhang Xu Zhi Yuan Wei Liying Yan Jie Qiao 2019Science China(Life Sciences)2019,62,7:4
16Identifying normal embryos from reciprocal translocation carriers by whole chromosome haplotyping显示文摘Reciprocal translocation is a chromosomal structural abnormality that arises when two non-homologous chromosomes rearrange and attach with each other, an incidence that occurs in about 1/500to 1/625 newborns (Mackie and Scriven, 2002). This event typically does not lead to any significant loss of genetic material, thus reciprocal translocation carriers do not exhibit any severeZhiqiang Yan Yuqian Wang Yanli Nie Xu Zhi Xiaohui Zhu Meng Qin Shuo Guan Yixin Ren Ying Kuo Di Chang Wei Chen Peng Yuan Liying Yan Jie Qiao 2018Journal of Genetics and Genomics2018,45,9:4

18Phenotypic identification of peanut germplasm for resistance to southern stem rot显示文摘Southern stem rot,caused by Sclerotium rolfsii Sacc.,is a destructive soil fungal disease of peanut in China and other countries.To evaluate resistant germplasm,a total of 256 peanut accessions were investigated on their resistance to southern stem rot in 3 environments by artificial inoculation.Variance analysis indicated that disease index was significantly influenced by environment,genotype and genotypeenvironment interactions.Peanut accessions of var.vulgaris type exhibited higher resistance to southern stem rot.Disease index was significantly negatively correlated with linoleic acid content,while positively correlated with oleic acid content.Six resistant accessions were identified,including Hua 28,Shandongzai,ICG 6326,Quanhua 7,Quanhua 9 and Guihua 836,with their disease indexes under 40 and mortality were less than 30%in the three environments.The identified resistant accessions showed the great potential to be applied in resistant peanut breeding,and would be good genetic resources for enhancing the resistance to southern stem rot.Pengmin Fan Wanduo Song Yanping Kang Liyun Wan Yong Lei Dongxin Huai Yuning Chen Xin Wang Huifang Jiang Liying Yan Boshou Liao 2020Oil Crop Science2020,5,4:3
19Advances in preimplantation genetic diagnosis/screening显示文摘Preimplantation genetic diagnosis(PGD)gives couples who have a high risk of transmitting genetic disorders to their baby the chance to have a healthy offspring through embryo genetic analysis and selection.Preimplantation genetic screening(PGS)is an effective method to select euploid embryos that may prevent repeated implantation failure or miscarriage.However,how and to whom PGS should be provided is a controversial topic.The first successful case of PGD of a human being was reported in 1990,and there have been tremendous improvements in this technology since then.Both embryo biopsy and genetic technologies have been improved dramatically,which increase the accuracy and expand the indications of PGD/PGS.YAN LiYing WEI Yuan HUANG Jin ZHU XiaoHui SHI XiaoDan XIA Xi YAN Jie LU CuiLing LIAN Ying LI Rong LIU Ping QIAO Jie 2014Science China(Life Sciences)2014,57,7:3
20Spin filtering magnetic modulation and spin-polarization switching in hybrid ferromagnet/semiconductor structures显示文摘Electron spin-polarization modulation with a ferromagnetic strip of in-plane magnetization is analyzed in a hybrid ferromagnet/semiconductor filter device.The dependencies of electron spin-polarization on the strip’s magnetization strength,width and position have been systematically investigated.A novel magnetic control spin-polarization switch is proposed by inserting a ferromagnetic metal(FM)strip eccentric in relation to off the center of the spin filter,which produces the first energy level spin-polarization reversal.It is believed to be of significant importance for the realization of semiconductor spintronics multiple-value logic devices.XU HuaiZhe WANG LiYing YAN QiQi ZHANG YaPing ZHANG ShiChao 2014Science China(Physics,Mechanics & Astronomy)2014,57,6:2
