1籼粳不育新位点的发现及其遗传分析显示文摘粳稻02428携有S-5n广亲和基因,然而与籼稻IR24杂交表现为半不育。对02428与IR24.Pecos、秋光等品种杂交的分离世代的小穗育性进行遗传分析,结果表明:02428与IR24之间的不育性受单基因控制,遗传规律符合单位点孢子体一配子体遗传模式,不育性由非S-5的新位点引起,美国品种Pecos具有复等位的中性基因;RFLP标记技术检测后初步确定,该新不育位点在第11染色体上的标记G24附件,与目前已报道的不育位点都不等位,新位点暂定名为S-p(t)。研究结果还显示,粳稻品种秋光与籼稻品种IR24之间的不育性受2个不育位点S-5和S-p(t)控制,其遗传效应表现有累加作用。朱旭东 王建林 钱前 张小惠 曾大力 朱立煌 闵绍楷 熊振民4 was controlled by two S-1oci S-5 and S-p(t) and its genetical effect was 1998Acta Genetica Sinica1998,25,3:10

4The Cosmic Dust in Suzhou Granite:Ablated Products of a Cometary ExplosionHu Zhong-wei,Wang Er-kang,Wan Yu-qiuDepartement of Astronomy,Nanjing University,Nanjing 210093,China Department of Earth Sdence,Nanjing University,Nanjing 210093,China Cosmic dust has been collected in large number from deap-sea sediments,Greenland ice deposits,the stratosphere and space,of cosmic dust,some are the unmelted micrometeorite,and most are the ablated products of me-teoroids in the atmosphere.Cosmic dusts were recovered from two sites of the 1908 Tunguska explosion and the 1965 Revelstoks explosion Since 1987,a large number of microspherules have been extracted from Suzhou granite of China Their suface and section structures,mineral and chemical composition show that these microspherules are of the ablated cosmic dust.The microspherules occurred in the inner contact complex intrusion.It suggests that the microspherules may be products of the same event and were aggergated in some strata and then captured by the emplacement of granitic magma.Although the microspherules are similare to other ablated cosmic dusts,there are some diferences.Our calculated results of cometary motion through the atmosphere and explosion show that the microspherules may be the ablated dust of a comet with mass above 1015g at its explosion near the ground. 1996紫金山天文台台刊1996,15,3:2
5Bioinformatical study on the proteomics and evolution of SARS-CoV显示文摘A novel coronavirus has been identified as the causative agent of the severe acute respiratory syndrome(SARS). For all the SARS-CoV associated proteins derivatedfrom the SARS-CoV genome, the physiochemical propertiessuch as the molecular weight, isoelectric point and extinction coefficient of each protein were calculated. Thetransmembrane segments and subcellular localization(SubLocation) prediction and conserved protein motifssearch against database were employed to analyze thefunction of SARS-CoV proteins. Also, the homology protein sequence alignment and evolutionary distance matrixcalculation between SARS-CoV associated proteins and the corresponding proteins of other coronaviruses wereemployed to identify the classification and phylogeneticrelationship between SARS-CoV and other coronaviruses.The results showed that SARS-CoV is a novel coronavirus which is different from any of the three previously knowngroups of coronviruses, but it is closer to BoCoV and MHV than to other coronaviruses. This study is in aid ofexperimental determination of SARS-CoV proteomics andthe development of antiviral vaccine.LIU Shuqun*, GUO Tao*, JI Xinglai & SUN Zhirong Institute of Bioinformatics, Department of Biological Sciences andBiotechnology, Tsinghua University, Beijing 100084, China * The two authors contributed equally to this work.

19Gastric vagal afferent inputs reach the glycemia-sensitive neurons of lateral hypothalamic area in the rat显示文摘The glycemia-sensitive neuron in lateral hypothalamic area (LHA) is one of the important central neural events involved in the feeding control. Electrophysio-logical studies have demonstrated that gastrointestinal vagal afferent inputs could convey the meal-related information of gastrointestinal tract to the hypothalamus. In this study, we examined whether the gastric vagal afferent inputs could reach the glycemia-sensitive neurons of the LHA by using in vivo extracellular recording technique in the rat. The results showed that stimulation of gastric vagal nerves elicited two types of the LHA neurons responses: the phasic response (93/116, 80.2%) and the change in cells firing pattern (23/116, 19.8%). Within the 93 cells that responded to the gastric vagal stimulation with a phasic response, 67 (72.0%) showed an inhibition in the cells firing rate, 26 (27.4%) were excited. Of the 23 cells that showed a change in the firing pattern, 13 responded to the gastric vagal stimulation with a long-lasting increase or decrease in firing rate, the remaining 10 cells turned their discrete spiking to the burst discharging. In addition, of 101 LHA neurons including the two types of responsive neurons, 73 (72.3%) were identified to be glyce-mia-sensitive neurons. These results demonstrated that the gastric vagal afferent inputs could reach the LHA and pre-dominantly reach those glycemia-sensitive neurons in the LHA. Presumably, the modulation of glycemia-sensitive neurons of LHA by the gastric vagal afferent inputs may play an important role in the short-term regulation of feed-ing behavior.ZHANG Yueping*, ZHU Jingning*, JIANG Jianming & WANG Jianjun Department of Biological Science and Technology, Nanjing University, Nanjing 210093, China * These two authors made equal contributions to this work. 2003Chinese Science Bulletin2003,48,6:1
