1花生种质资源果腐病的抗性评价显示文摘花生果腐病是一种由真菌引起的世界性的严重病害,直接影响花生的产量及品质。通过田间自然发病对引进的77份美国资源和39份国内资源进行连续2年的鉴定,筛选抗果腐病的花生种质资源,为花生抗果腐病育种提供优异材料。结果表明:供试花生材料间的受害指数差异极显著(P<0.01),两年间的差异也达到显著水平(P<0.05)。根据受害指数的聚类分析将供试花生材料的果腐病抗性分为高抗、抗、中抗、感病和高感病5组,该结果作为花生果腐病抗性评价标准,能够明确评价供试花生材料对果腐病的抗性。综合两年抗性表现较一致的96份种质,筛选到高抗材料2份,平均受害指数分别为16.67和21.91;抗性材料6份,平均受害指数分布在26.33~42.41之间;中抗材料32份,平均受害指数在45.19~60之间;感病材料34份,平均受害指数在60.87~74.39之间;高感材料22份,平均受害指数在75.27~83.34之间。该结果为评价花生果腐病抗性和合理利用种质资源进行花生抗病品种遗传改良提供了参考和优异材料。何美敬 刘阳杰 崔顺立 杨鑫雷 穆国俊 Charles Y.Chen 郭巍 刘立峰 2018植物遗传资源学报2018,19,4:11

9Observation of the Crab Nebula with LHAASO-KM2A−a performance study显示文摘A sub-array of the Large High Altitude Air Shower Observatory(LHAASO),KM2A is mainly designed to observe a large fraction of the northern sky to hunt for γ-ray sources at energies above 10 TeV.Even though the detector construction is still underway,half of the KM2A array has been operating stably since the end of 2019.In this paper,we present the KM2A data analysis pipeline and the first observation of the Crab Nebula,a standard candle in very high energy γ-ray astronomy.We detect γ-ray signals from the Crab Nebula in both energy ranges of 10-100 TeV and>100 TeV with high significance,by analyzing the KM2A data of 136 live days between December 2019 and May 2020.With the observations,we test the detector performance,including angular resolution,pointing accuracy and cosmic-ray background rejection power.The energy spectrum of the Crab Nebula in the energy range 10-250 TeV fits well with a single power-law function dN/dE=(1.13±0.05stat±0.08sys)×10^(-14).(E/20 TeV)-309±0.06stat±0.02syscm^(-2) s^(-1) TeV^(-1).It is consistent with previous measurements by other experiments.This opens a new window of γ-ray astronomy above 0.1 PeV through which new ultrahigh-energy γ-ray phenomena,such as cosmic PeVatrons,might be discovered.F.Aharonian Q.An Axikegu L.X.Bai Y.X.Bai Y.W.Bao D.Bastieri X.J.Bi Y.J.Bi H.Cai J.T.Cai Z.Cao J.Chang J.F.Chang X.C.Chang B.M.Chen J.Chen L.Chen M.J.Chen M.L.Chen Q.H.Chen S.H.Chen S.Z.Chen T.L.Chen X.L.Chen Y.Chen N.Cheng Y.D.Cheng S.W.Cui X.H.Cui Y.D.Cui B.Z.Dai H.L.Dai Z.G.Dai D.della Volpe B.D'Ettorre Piazzoli X.J.Dong J.H.Fan Y.Z.Fan Z.X.Fan J.Fang K.Fang C.F.Feng L.Feng S.H.Feng Y.L.Feng B.Gao C.D.Gao Q.Gao W.Gao M.M.Ge L.S.Geng G.H.Gong Q.B.Gou M.H.Gu J.G.Guo X.L.Guo Y.Q.Guo Y.Y.Guo Y.A.Han H.H.He H.N.He J.C.He S.L.He X.B.He Y.He M.Heller Y.K.Hor C.Hou X.Hou H.B.Hu S.Hu S.C.Hu X.J.Hu D.H.Huang Q.L.Huang W.H.Huang X.T.Huang Z.C.Huang F.Ji X.L.Ji H.Y.Jia K.Jiang Z.J.Jiang C.Jin D.Kuleshov K.Levochkin B.B.Li C.Li F.Li H.B.Li H.C.Li H.Y.Li J.Li K.Li W.L.Li X.Li X.R.Li Y.Li Y.Z.Li Z.Li E.W.Liang Y.F.Liang S.J.Lin B.Liu C.Liu D.Liu H.Liu H.D.Liu J.Liu J.L.Liu J.S.Liu J.Y.Liu M.Y.Liu R.Y.Liu S.M.Liu W.Liu Y.N.Liu Z.X.Liu W.J.Long R.Lu H.K.Lv B.Q.Ma L.L.Ma X.H.Ma J.R.Mao A.Masood W.Mitthumsiri T.Montaruli Y.C.Nan B.Y.Pang P.Pattarakijwanich Z.Y.Pei M.Y.Qi D.Ruffolo V.Rulev A.Sáiz L.Shao O.Shchegolev X.D.Sheng J.R.Shi H.C.Song Yu.V.Stenkin V.Stepanov Q.N.Sun X.N.Sun Z.B.Sun P.H.T.Tam Z.B.Tang W.W.Tian B.D.Wang C.Wang H.Wang H.G.Wang J.C.Wang J.S.Wang L.P.Wang L.Y.Wang R.N.Wang W.Wang X.G.Wang X.J.Wang X.Y.Wang Y.D.Wang Y.J.Wang Y.P.Wang Z.Wang Z.H.Wang Z.X.Wang D.M.Wei J.J.Wei Y.J.Wei T.Wen C.Y.Wu H.R.Wu S.Wu W.X.Wu X.F.Wu S.Q.Xi J.Xia J.J.Xia G.M.Xiang G.Xiao H.B.Xiao G.G.Xin Y.L.Xin Y.Xing D.L.Xu R.X.Xu L.Xue D.H.Yan C.W.Yang F.F.Yang J.Y.Yang L.L.Yang M.J.Yang R.Z.Yang S.B.Yang Y.H.Yao Z.G.Yao Y.M.Ye L.Q.Yin N.Yin X.H.You Z.Y.You Y.H.Yu Q.Yuan H.D.Zeng T.X.Zeng W.Zeng Z.K.Zeng M.Zha X.X.Zhai B.B.Zhang H.M.Zhang H.Y.Zhang J.L.Zhang J.W.Zhang L.Zhang L.X.Zhang P.F.Zhang P.P.Zhang R.Zhang S.R.Zhang S.S.Zhang X.Zhang X.P.Zhang Y.Zhang Y.F.Zhang Y.L.Zhang B.Zhao J.Zhao L.Zhao L.Z.Zhao S.P.Zhao F.Zheng Y.Zheng B.Zhou H.Zhou J.N.Zhou P.Zhou R.Zhou X.X.Zhou C.G.Zhu F.R.Zhu H.Zhu K.J.Zhu X.Zuo 2021Chinese Physics C2021,45,2:2

12WIPER: Weighted in-Path Edge Ranking for biomolecular association networks显示文摘Background:In network biology researchers generate biomolecular networks with candidate genes or proteins experimentally-derived from high-throughput data and known biomolecular associations.Current bioinformatics research focuses on characterizing candidate genes/proteins,or nodes,with network characteristics,e.g.,betweenness centrality.However,there have been few research reports to characterize and prioritize biomolecular associations('edges'),which can represent gene regulatory events essential to biological processes.Method:We developed Weighted In-Path Edge Ranking(WIPER),a new computational algorithm which can help evaluate all biomolecular interactions/associations('edges')in a network model and generate a rank order of every edge based on their in-path traversal scores and statistical significance test result.To validate whether WIPER worked as we designed,we tested the algorithm on synthetic network models.Results:Our results showed WIPER can reliably discover both critical'well traversed in-path edges',which are statistically more traversed than normal edges,and'peripheral in-path edges',which are less traversed than normal edges.Compared with other simple measures such as betweenness centrality,WIPER provides better biological interpretations.In the case study of analyzing postanal pig hearts gene expression,WIPER highlighted new signaling pathways suggestive of cardiomyocyte regeneration and proliferation.In the case study of Alzheimer's disease genetic disorder association,WIPER reports SRC:APP,AR:APP,APP:FYN,and APP:NES edges(gene-gene associations)both statistically and biologically important from PubMed co-citation.Conclusion:We believe that WIPER will become an essential software tool to help biologists discover and validate essential signaling/regulatory events from high-throughput biology data in the context of biological networks.Availability:The free WIPER API is described at the website(discovery.informatics.uab.edu/wiper/).Zongliang Yue Thanh Nguyen Eric Zhang Jianyi Zhang Jake Y.Chen 2019Quantitative Biology2019,7,4:1
