3A rare Waxy allele coordinately improves rice eating and cooking quality and grain transparency显示文摘In rice(Oryza sativa), amylose content(AC) is the major factor that determines eating and cooking quality(ECQ). The diversity in AC is largely attributed to natural allelic variation at the Waxy(Wx)locus. Here we identified a rare Wx allele, Wx^(mw) ,which combines a favorable AC, improved ECQ and grain transparency. Based on a phylogenetic analysis of Wx genomic sequences from 370 rice accessions, we speculated that Wx^(mw) may have derived from recombination between two important natural Wx alleles, Wx^(in) and Wx^(b). We validated the effects of Wx^(mw) on rice grain quality using both transgenic lines and near-isogenic lines(NILs). When introgressed into the japonica Nipponbare(NIP) background, Wx^(mw) resulted in a moderate AC that was intermediate between that of NILs carrying the Wx^(b)allele and NILs with the Wx^(mp) allele. Notably, mature grains of NILs fixed for Wx^(mw) had an improved transparent endosperm relative to soft rice. Further, we introduced Wx^(mw) into a high-yielding japonica cultivar via molecular marker-assisted selection: the introgressed lines exhibited clear improvements in ECQ and endosperm transparency. Our results suggest that Wx^(mw) is a promising allele to improve grain quality, especially ECQ and grain transparency of high-yielding japonica cultivars, in rice breeding programs.Changquan Zhang Yong Yang Shengjie Chen Xueju Liu Jihui Zhu Lihui Zhou Yan Lu Qianfeng Li Xiaolei Fan Shuzhu Tang Minghong Gu Qiaoquan Liu 2021Journal of Integrative Plant Biology2021,63,5:18
4Mapping of two new brown planthopper resistance genes from wild rice显示文摘A brown planthopper (BPH) resistance line, B5, derived its resistance genes from the wild rice Oryza offici-nalis Wall exwatt, was hybridized with Taichung Native 1, a cultivar highly susceptible to BPH. A mapping population composed of randomly selected 167 F2 individuals was used for determining the BPH resistance genes by the restriction fragment length polymorphism analysis (RFLP). Bulked segregant analysis was conducted to identify RFLP makers linked to the BPH resistance genes in B5. The results indicated that the markers linked to BPH resistance are located at two genomic regions on the long arm of chromosome 3 and the short arm of chromosome 4, respectively. The existence of the two loci was further assessed by the quantitative trait locus (QTL) analysis. We located the two loci at a 3.2 cM interval between G1318 and R1925 on chromosome 3 and a 1.2 cM interval between C820 and S11182 on chromosome 4. Comparison with the BPH genes that have been reported indicated that the BPH resistance genesWANG Buna HUANG Zhen SHU Lihui REN Xiang LI Xianghua HE Guangcun 2001Chinese Science Bulletin2001,46,13:14

6Development of fractures in soft rock surrounding a roadway and their control显示文摘As the excavation of roadway,new fractures will be formed and the pre-existing fractures extend with the redistribution of stress in surrounding rocks.Eventually,fracture zone and bed separation are formed in rocks because of the developed fractures.Therefore,mastering the fracture evolution of surrounding rocks is very important to maintain the stability of roadway.The surrounding rocks of main haulage roadway in a certain coal mine is so broken and loose that the supporting is very difficult.Based on comprehensive analysis of the engineering geological conditions,a sight instrument was used to observe the fractures of internal surrounding rocks.Four indices,i.e.,the width of fracture zone W,the number of fractures n,the width of fractures d and rock fracture designation RFD,are put forward to evaluate the fracture development.According to the evolution rules of the soft rock roadway from this paper,control principles by stages and by regions are presented through the research.At the same time,the best time of grouting reinforcement is determined on the basis of fracture saturation.Field practice shows that the roadway can satisfy normal production during service periods by suitable first support and grouting reinforcement.Li Xuehua Yao Qiangling Man Jiankang Chen Chaoqun He Lihui 2011Mining Science and Technology2011,21,4:12
7Anti-diabetic effects and mechanisms of action of a Chinese herbal medicine preparation JQ-R in vitro and in diabetic KKAy mice显示文摘Refined-JQ(JQ-R) is a mixture of refined extracts from Coptis chinensis(Ranunculaceae),Astragalus membranaceus(Leguminosae) and Lonicera japonica(Caprifoliaceae), the three major herbs of Jin Qi-Jiang Tang tablet, a traditional Chinese medicine(TCM) formula. The mechanisms by which JQ-R regulates glucose metabolism and improves insulin sensitivity were studied in type 2 diabetic KK^(Ay)mice and insulin-resistant L6 myotubes. To investigate the mechanisms by which JQ-R improves insulin sensitivity, a model of insulin-resistant cells induced with palmitic acid(PA) was established in L6 myotubes. Glucose uptake and expression of factors involved in insulin signaling, stress, and inflammatory pathways were detected by immunoblotting. JQ-R showed beneficial effects on glucose homeostasis and insulin resistance in a euglycemic clamp experiment and decreased fasting insulin levels in diabetic KK^(Ay)mice. JQ-R also improved the plasma lipid profiles. JQ-R directly increased the activity of superoxide dismutase(SOD) and decreased malondialdehyde(MDA) as well as inducible nitric oxide synthase(iNOS) levels in insulin-resistant L6 cells, and elevated the insulin-stimulated glucose uptake with upregulated phosphorylation of AKT. The phosphorylation levels of nuclear factor kappa B(NF-κB p65), inhibitor of NF-κB(IκBα), c-Jun N-terminal kinase(JNK1/2) and extracellular-signal-regulated kinases(ERK1/2) were also changed after JQ-R treatment compared with the control group. Together these findings suggest that JQ-R improved glucose and lipid metabolism in diabetic KK^(Ay)mice. JQ-R directly enhanced insulin-stimulated glucose uptake in insulin-resistant myotubes with improved insulin signalling and inflammatory response and oxidative stress. JQ-R could be a candidate to achieve improved glucose metabolism and insulin sensitivity in type 2 diabetes mellitus.Quan Liu Shuainan Liu Lihui Gao Sujuan Sun Yi Huan Caina Li Yue Wang Nan Guo Zhufang Shen 2017Acta Pharmaceutica Sinica B2017,7,4:11
8Estimation and prediction of plastic waste annual input into the sea from China显示文摘Marine plastic debris has been a pervasive issue since the last century, and research on its sources and fates plays a vital role in the establishment of mitigation measures. However, data on the quantity of plastic waste that enters the sea on a certain timescale remain largely unavailable in China. Here, we established a model using material flow analysis method based on life cycle assessment to follow plastic product from primary plastic to plastic waste with statistical data and monitoring data from accurate sources. This model can be used to estimate and forecast the annual input of plastic waste into the sea from China until 2020. In 2011, 0.547 3–0.751 5 million tons of plastic waste entered the seas in China, with a growth rate of 4.55% per year until 2017. And the amount will decrease to0.257 1 to 0.353 1 million tons in 2020 under the influence of governmental management. The amount of plastic waste discharged from coastal areas calculated in this study was much larger than that from river, thus it is suggested to strengthen the governance and control of plastic waste in coastal fishery activities in China in order to reduce the amount of marine plastic waste input.BAI Mengyu ZHU Lixin AN Lihui PENG Guyu LI Daoji 2018Acta Oceanologica Sinica2018,37,11:11
9A human circulating immune cell landscape in aging and COVID-19显示文摘Age-associated changes in immune cells have been linked to an increased risk for infection.However,a global and detailed characterization of the changes that human circulating immune cells undergo with age is lacking.Here,we combined scRNA-seq,mass cytometry and sCATAC-seq to compare immune cell types in peripheral blood collected from young and old subjects and patients with COVID-19.We found that the immune cell landscape was reprogrammed with age and was characterized by T cell polarization from naive and memory cells to effector,cytotoxic,exhausted and reg-ulatory cells,along with increased late natural killer cells,age-associated B cells,inflammatory monocytes and age-associated dendritic cells.In addition,the expression of genes,which were implicated in coron-avirus susceptibility,was upregulated in a cell subtype-specific manner with age.Notably,COVID-19 promoted age-induced immune cell polarization and gene expression related to inflammation and cellular senes-cence.Therefore,these findings suggest that a dysreg-ulated immune system and increased gene expression associated with SARS-CoV-2 susceptibility may at least partially account for COVID-19 vulnerability in the elderly.Yingfeng Zheng Xiuxing Liu Wenqing Le Lihui Xie He Li Wen Wen Si Wang Shuai Ma Zhaohao Huang Jinguo Ye Wen Shi Yanxia Ye Zunpeng Liu Moshi Song Weiqi Zhang Jing-Dong J.Han Juan Carlos lzpisua Belmonte Chuanle Xiao Jing Qu Hongyang Wang Guang-Hui Liu Wenru Su 2020Protein & Cell2020,11,10:10

13Single-cell analysis reveals bronchoalveolar epithelial dysfunction in COVID-19 patients显示文摘Dear Editor,In 2019,a zoonotic coronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was identified as the causative agent of Coronavirus Disease 2019(COVID-19).As of 8 June 2020,the World Health Organization(WHO)has reported 6,912,751 globally confirmed cases with 400,469 deaths.Although generally causes mild disease,SARS-CoV-2 infection can result in serious outcomes,including acute lung injury(ALI)and acute respiratory distress syndrome(ARDS),the leading cause of mortality in patients with comorbidities.Recent autopsy studies of COVID-19 patients revealed mononuclear infiltration and excessive production of mucus in the infected lung,especially in the damaged small airways and alveoli(Bian and Team,2020;Liu et al.,2020).Jiangping He Shuijiang Cai Huijian Feng Baomei Cai Lihui Lin Yuanbang Mai Yinqiang Fan Airu Zhu Huang Huang Junjie Shi Dingxin Li' Yuanjie Wei Yueping Li Yingying Zhao’ Yuejun Pan He Liu Xiaoneng Mo Xi He Shangtao Cao FengYu Hu Jincun Zhao Jie Wang Nanshan Zhong Xinwen Chen Xilong Deng Jiekai Chen 2020Protein & Cell2020,11,9:7
14Biofilm Microenvironment-Responsive Nanotheranostics for Dual-Mode Imaging and Hypoxia-Relief-Enhanced Photodynamic Therapy of Bacterial Infections显示文摘The formation of bacterial biofilms closely associates with infectious diseases.Until now,precise diagnosis and effective treatment of bacterial biofilm infections are still in great need.Herein,a novel multifunctional theranostic nanoplatform based on MnO_(2)nanosheets(MnO_(2)NSs)has been designed to achieve pH-responsive dual-mode imaging and hypoxia-relief-enhanced antimicrobial photodynamic therapy(aPDT)of bacterial biofilm infections.In this study,MnO_(2)NSs were modified with bovine serum albumin(BSA)and polyethylene glycol(PEG)and then loaded with chlorin e_(6)(Ce_(6))as photosensitizer to form MnO_(2)-BSA/PEG-Ce_(6)nanosheets(MBP-Ce_(6)NSs).After being delivered into the bacterial biofilm-infected tissues,the MBP-Ce_(6)NSs could be decomposed in acidic biofilm microenvironment and release Ce_(6)with Mn^(2+),which subsequently activate both fluorescence(FL)and magnetic resonance(MR)signals for effective dual-mode FL/MR imaging of bacterial biofilm infections.Meanwhile,MnO_(2)could catalyze the decomposing of H2O_(2)in biofilm-infected tissues into O_(2)and relieve the hypoxic condition of biofilm,which significantly enhances the efficacy of aPDT.An in vitro study showed that MBP-Ce_(6)NSs could significantly reduce the number of methicillin-resistant Staphylococcus aureus(MRSA)in biofilms after 635nm laser irradiation.Guided by FL/MR imaging,MRSA biofilm-infected mice can be efficiently treated by MBP-Ce_(6)NSs-based aPDT.Overall,MBP-Ce_(6)NSs not only possess biofilm microenvironment-responsive dual-mode FL/MR imaging ability but also have significantly enhanced aPDT efficacy by relieving the hypoxia habitat of biofilm,which provides a promising theranostic nanoplatform for bacterial biofilm infections.Weijun Xiu Siyu Gan Qirui Wen Qiu Qiu Sulai Dai Heng Dong Qiang Li Lihui Yuwen Lixing Weng Zhaogang Teng Yongbin Mou Lianhui Wang 2020Research2020,,1:7
15Highly stable lead-free Cs3Bi2I9 perovskite nanoplates for photodetection applications显示文摘Lead halide perovskites have received tremendous attentions recently for their excellent properties such as high light absorption coefficient and long charge carrier diffusion length. However, the stability issues and the existence of toxic lead cations have largely limited their applications in optoelectronic area. Herein, we report the synthesis and investigation of highly stable and lead-free Cs3Bi2I9 perovskite nanoplates for visible light photodetection applications. The Cs3Bi2I9 nanoplates were synthesized through a facile solution-processed method, which is also applicable to various substrates. The achieved nanoplates present very good crystal quality and exhibit excellent long-term stability even exposed in moist air for several months. Photodetectors were constructed based on these high-quality perovskite nanoplates for the first time, and display a maximum photoresponsivity of 33.1 mA/W under the illumination of 450 nm laser, which is six times higher than the solution-synthesized CH3NH3PbI3 nanowire photodetectors. The specific detectivity of these devices can reach up to 10^10 Jones. Additionally, the devices exhibit fast rise and decay time of 10.2 and 37.2 ms, respectively, and highly stable photoswitching behavior with their photoresponse well retaining under alternating light and darkness. This work opens up a new opportunity for stable and low-toxic perovskite-based optoelectronic applications.Zhaoyang Qi Xianwei Fu Tiefeng Yang Dong Li Peng Fan Honglai Li Feng Jiang Lihui Li Ziyu Luo Xiujuan Zhuang Anlian Pan 2019Nano Research2019,12,8:7

17Preparation and Characterization of Natural Bamboo Fiber显示文摘In this study,natural bamboo fiber was prepared combining chemical pretreatment with mechanical disc refining,opening,and carding.An orthogonal experiment was designed based on four factors and three levels;thereafter,the manufacturing process was optimized.The length,diameter,tensile strength,and elastic modulus of the bamboo fiber were determined,and the crystallinity and morphology of the fiber were analyzed using X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results showed that the optimum parameters for the chemical pretreatment were a cooking temperature of 130℃,heating time of 2 h,NaOH dosage of 2%,and Na2SO3 dosage of 10%.The cooking yield of bamboo chips was 89.5%,and the carding yield of natural bamboo fiber was 43.0% under the optimum conditions.The length,diameter,tensile strength,and elastic modulus of the obtained fiber were 36.71 mm,0.285 mm,407 MPa,and 27.7 GPa,respectively.XRD analysis and SEM observations showed that the technology used in this study can produce bright and compact natural bamboo fibers with high crystallinity.Kaixuan Li Qingxian Miao He Zhao Jiawei Yang Haitao Cheng Lihui Chen 2020Paper And Biomaterials2020,5,2:6
18UFMylation of RPL26 links translocation-associated quality control to endoplasmic reticulum protein homeostasis显示文摘Protein biogenesis at the endoplasmic reticulum(ER)in eukaryotic cells is monitored by a protein quality control system named ER-associated protein degradation(ERAD).While there has been substantial progress in understanding how ERAD eliminates defective polypeptides generated from erroneous folding,how cells remove nascent chains stalled in the translocon during co-translational protein insertion into the ER is unclear.Here we show that ribosome stalling during protein translocation induces the attachment of UFM1,a ubiquitin-like modifier,to two conserved lysine residues near the COOH-terminus of the 60S ribosomal subunit RPL26(uL24)at the ER.Strikingly,RPL26 UFMylation enables the degradation of stalled nascent chains,but unlike ERAD or previously established cytosolic ribosome-associated quality control(RQC),which uses proteasome to degrade their client proteins,ribosome UFMylation promotes the targeting of a translocation-arrested ER protein to lysosomes for degradation.RPL26 UFMylation is upregulated during erythroid differentiation to cope with increased secretory flow,and compromising UFMylation impairs protein secretion,and ultimately hemoglobin production.We propose that in metazoan,co-translational protein translocation into the ER is safeguarded by a UFMylation-dependent protein quality control mechanism,which when impaired causes anemia in mice and abnormal neuronal development in humans.Lihui Wang Yue Xu Heather Rogers Layla Saidi Constance Tom Noguchi Honglin Li Jonathan Wilson Yewdell Nicholas Raymond Guydosh Yihong Ye 2020Cell Research2020,30,1:5
19Effect of in ovo folic acid injection on hepatic IGF2 expression and embryo growth of broilers显示文摘Background: Insulin-like factor 2(IGF2) plays an important role in embryonic growth process by modulating intermediary metabolism and cell proliferation. Folic acid is involved in one carbon metabolism and contributes to DNA methylation which is related to gene expression. The purpose of this study was to explore whether folic acid could regulate IGF2 expression via epigenetic mechanism and further promote embryonic growth of new-hatched broilers.Methods: In the present study, 360 fertile eggs were selected and randomly assigned to four treatments. On11 embryonic day of incubation(E11), 0, 50, 100 and 150 μg folic acid were injected into eggs respectively.After hatched, growth performance of broilers were calculated. Hepatic IGF2 expression, methylation level and chromatin structure of promoter region were analyzed.Results: Results have showed that IGF2 expression was up-regulated in 150 μg folic acid group(P < 0.05) and other two dose of folic acid did not affect gene expression(P > 0.05). Meanwhile, methylation level of IGF2 promoter were lower in 100 and 150 μg groups, which was consistent with lower expression of DNA methyltransferase1(DNMT1)(P < 0.05). What's more, chromatin looseness of IGF2 promoter was higher in 150 μg group than control group(P < 0.05). Further, birth weight(BW), liver and bursa index of new-hatched chickens in 150 μg folic acid group were higher than the other groups(P < 0.05). There were positive correlations between hepatic IGF2 expression and BW and organs index(P < 0.05).Conclusion: In conclusion, our data have demonstrated that 150 μg folic acid injection on E11 could up-regulate IGF2 expression by modulating DNA hypomethylation and improving chromatin accessibility in the gene promoter region,and ulteriorly facilitate embryonic growth and organ development of broilers.Yanli Liu Lihui Zhi Jing Shen Shizhao Li Junhu Yao Xiaojun Yang 2017Journal of Animal Science and Biotechnology2017,8,1:5
