| 1 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022，15，9： | 6 |
| 2 | Haplotype-resolved genome of diploid ginger (Zingiber officinale) and its unique gingerol biosynthetic pathway显示文摘Ginger(Zingiber officinale),the type species of Zingiberaceae,is one of the most widespread medicinal plants and spices.Here,we report a high-quality,chromosome-scale reference genome of ginger‘Zhugen’,a traditionally cultivated ginger in Southwest China used as a fresh vegetable,assembled from PacBio long reads,Illumina short reads,and high-throughput chromosome conformation capture(Hi-C)reads.The ginger genome was phased into two haplotypes,haplotype 1(1.53 Gb with a contig N50 of 4.68 M)and haplotype 0(1.51 Gb with a contig N50 of 5.28 M).Homologous ginger chromosomes maintained excellent gene pair collinearity.In 17,226 pairs of allelic genes,11.9%exhibited differential expression between alleles.Based on the results of ginger genome sequencing,transcriptome analysis,and metabolomic analysis,we proposed a backbone biosynthetic pathway of gingerol analogs,which consists of 12 enzymatic gene families,PAL,C4H,4CL,CST,C3’H,C3OMT,CCOMT,CSE,PKS,AOR,DHN,and DHT.These analyses also identified the likely transcription factor networks that regulate the synthesis of gingerol analogs.Overall,this study serves as an excellent resource for further research on ginger biology and breeding,lays a foundation for a better understanding of ginger evolution,and presents an intact biosynthetic pathway for species-specific gingerol biosynthesis. | Hong-Lei Li Lin Wu Zhaoming Dong Yusong Jiang Sanjie Jiang Haitao Xing Qiang Li Guocheng Liu Shuming Tian Zhangyan Wu Bin Wu Zhexin Li Ping Zhao Yan Zhang Jianmin Tang Jiabao Xu Ke Huang Xia Liu Wenlin Zhang Qinhong Liao Yun Ren Xinzheng Huang Qingzhi Li Chengyong Li Yi Wang Baskaran Xavier-Ravi Honghai Li Yang Liu Tao Wan Qinhu Liu Yong Zou Jianbo Jian Qingyou Xia Yiqing Liu | 2021 | Horticulture Research2021，8，1： | 2 |

| 4 | Application of three Ln(Ⅲ)-coordination polymers in fields of luminescence,antibacteria and detection of Fe^(3+) and 4-nitrophenol显示文摘Three lanthanide-based coordination polymers(Ln-CPs) with layered structure,{[La_(2)(L)_(3)(DMF)(H_(2)O)_(3)]·H_(2)O}_n(1),{[Eu_(2)(L)_(3)(DMF)_(2)(H_(2)O)]·(H_(2)O)}_n(2){Tb_(2)(L)_(3)(DMF)_(2)(H_(2)O)]·H_(2)O}n(3) were successfully synthesized from H_(2)L(N,N'-bis(4-carbozylbenzyl)aniline).Remarkably,compound 3 has extremely high sensitivity to 4-nitrophenol.When the concentration of 4-nitrophenol reaches 5.98 × 10^(-3) mmol/L,the fluorescence intensity of compound 3 is quenched by 59%.The calculated K_(SV) is 7.56 × 10~4 and limit of detection(LOD) is 4.73 μg/L.3 exhibits a highly sensitive detection towards Fe^(3+) and compound 2 shows outstanding antibacterial effects on Staphylococcus aureus,re spectively.The white light emission was also investigated by changing the mixing ratio of LaNO_(3),EuNO_(3) and TbNO_(3) during the preparation of coordination polymers. | Lun Zhao Yue Han Guanlin Guo Helong Bai Zhexin Wang Hongwei Jing Guanying Song Ziyun Wang Jiayu Li Jia Li | 2023 | Journal of Rare Earths2023，41，9： | 0 |
| 5 | Design of a multichannel photonic crystal dielectric laser accelerator显示文摘To be useful for most scientific and medical applications,compact particle accelerators will require much higher average current than enabled by current architectures.For this purpose,we propose a photonic crystal architecture for a dielectric laser accelerator,referred to as a multi-input multi-output silicon accelerator(MIMOSA),that enables simultancous acceleration of multiple electron beams,increasing the total electron throughput by at least I order of magnitude.To achieve this,we show that the photonic crystal must support a mode at the I point in reciprocal space,with a normalized frequency equal to the normalized speed of the phase-matched electron.We show that the figure of merit of the MIMOSA can be inferred from the eigenmodes of the corresponding infinitely periodic structure,which provides a powerful approach to design such devices.Additionally,we extend the MIMOSA architecture to electron deflectors and other clectron manipulation functionalities.These additional functionalities,combined with the increased electron throughput of these devices,permit all-optical on-chip manipulation of electron beams in a fully integrated architecture compatible with current fabrication technologies,which opens the way to unconventional electron beam shaping,imaging,and radiationg encration. | ZHEXIN ZHAO DYLAN S.BLACK R.JOEL ENGLAND TYLER W.HUGHES YU MIAO DOLAV SOLGAARD ROBERT L.BYER SHANHUI FAN | 2020 | Photonics Research2020，8，10： | 0 |
| 6 | Effect of compound Sophorae Flavescentis Jiechangrongcapsule on expression of NF-κB p65 and STAT6 in theintestinal mucosa of patients with ulcerative colitis显示文摘The effects of compound Sophorae Flavescen-tis Jiechangrong capsule(CSFJC)on the expression of nuclear factor-κB p65(NF-κB p65)and signal transducer and activator of transcription 6(STAT6)in the intestinal mucosa of patients with ulcerative colitis and the possible mechanism were investigated.Eighteen patients with ulcerative colitis were randomly divided into a traditional Chinese medicine(TCM)group(n=11)treated by CSFJC and a western medicine(WM)group(n=7)treated by Sulfasalazine tablets.The treatment duration lasted eight weeks.Before and after the treatment,the symptoms and the physical signs were observed,and the routine stool test,the colonoscopy,and pathological examination were performed in the two groups.The expression levels of NF-κB p65 and STAT6 were detected by using immuno-histochemistry.The results showed that the total effective rate of the curative effectiveness in TCM and WM groups was 100%and 71.4%,respectively,and the total effective rate of colonic mucosa lesion in TCM and WM groups was 90.9%and 71.4%,respectively,with the differences being significant(all P<0.05).The total effective rate of syndromes of damp-heat blocking according to the TCM in TCM and WM groups was 90.9%and 71.4%,respectively.After the treatment,the expression of NF-κB p65 and STAT6 in the two groups was decreased,and the decrease of NF-κB p65 and STAT6 expression in TCM group was more significant than in WM group(P<0.05).It was concluded that CSFJC can inhibit the activation and expression of NF-κB p65 and STAT6 in the intestinal mucosa of patients with ulcerative colitis,which is a possible mechanism for CSFJC treating ulcerative colitis. | Heng FAN Jia ZHAO Lin SHEN Qing TANG Zhexin SHOU Li LIANG Yi LIAO Xiaoyan CHEN | 2009 | Frontiers of Medicine2009，3，4： | 0 |
