The interaction between dansyl-labeled pollen calmodulin (D-pCaM) and synthesized peptides was studied in the presence of Ca2+ by fluorescence spectra. It is Found that Gly/L-Ala --> D-Ala substitution in peptide chains caused great changes in their affinity for pCaM. Besides. our data provided evidence on the dissimilarity of different CaMs although they have highly-conserved structures. A preliminary study was carried out on the effects of CaM-binding peptides on cellular signal transduction, cell proliferation, showing the participation of CaM in cell functions mentioned above.

? The intensive extensional deformation in the eastern part of the chinese continent in Late Mesozoic time (J3-K1) caused the formation of largescale fault basin system in Northeastern china block, metamorphic core complexes in North china block and widespread volcanic eruption and granitic intrusive in eastern china. Generally, the deformation has been interpreted as subduction tectonics along the eastern continental margin. We suggest that the combination effect of the subduction and collision in Tethys domain and the subduction from Pacific side and the mantle upwelling beneath the lithosphere. This event controlled the Late Jurassic to Early Cretaceous tectonic history in eastern china.

The effect of sodium nitroprusside (SNP), a donor of nitric oxide, on meiotic maturation of mouse oo-cytes was studied by injecting Nw-nitro-L-arginine methyl ester (L-NAME) intra-peritoneal (ip), a nitric oxide synthase inhibitor, or culturing oocytes in the medium supplemented with L-NAME or hypoxanthine (HX) to arrest the sponta-neous oocyte maturation in vitro. The results showed that the inhibitory effect of L-NAME by injecting 10 mg/kg ip on extrusion of the first polar body only could be reversed by injecting 2.5 mg/kg SNP with L-NAME simultaneously (P 6,10-5mol/L) significantly stimulated meiotic matu-ration to metaphase Ⅱ stages in cumulus enclosed oocytes in the presence of HX. However, other concentrations of SNP (10-8, 10-4, 10-3 mol/L) had no effect on HX-arrested oocyte meiotic maturation. The optimal concentration of SNP on CEOs had no effect on DOs. The dose of 10-3 mol/LL-NAME demonstrated a significant suppression in formation of PB1, but not in GVBD. This inhibition was reversed by the addi-tion of SNP. These results indicated that the physiological levels of NO produced by cumulus cells could stimulate mei-otic maturation of mouse oocytes both in vivo and in vitro.

Four generations of mineral assemblages have been identified in ultrahigh-pressure (UHP) eclogites from the Hong’an area,recording four metamorphic stages of the exhumation trajectory,i.e.,garnet+omphacite+kyanite+ zoisite/epidote+rutile+coesite formed at the UHP stage,garnet+omphacite+paragonite+phengite+amphibole+epidote+quartz at the high-pressure (HP) eclogitic stage,amphibole+epidote+albite-oligoclase+paragonite+quartz at the epidote-amphibolite facies(EA) stage,and actinolite+ albite and pumpellyite+albite+K-feldspar+muscovite+chlorite+margarite+epidote+quartz at the greenschist facies(GS) *** formed at the UHP stage was overgrown by atoll garnet at the HP stage. X-ray images,mineral compositions and compositional profiles indicate that the UHP garnet experienced a variable Fe-Mg modification in response to Fe-Mg exchange between garnet and omphacite prior to the overgrowth of atoll HP garnet.A volume diffusion zone was also observed between the UHP and HP *** following P-T conditions were estimated for these mineral assemblages:480 to 560℃and 2.5 to 2.9 GPa with median values of 520℃and 2.8 GPa at UHP stage,575 to 685℃and 1.6 to 1.9 GPa with the average results of 634±37℃and 1.8±0.06 GPa at the HP stage,500 to 640℃and 0.4 to 1 GPa at the EA stage,and 160 to 320℃and 0.2 to 0.8 GPa at the GS *** Hong’an UHP eclogites experienced a temperature increase of over 100℃from the UHP to HP stages and continued to exhume from the HP to EA stages through a process of approximately isothermal depression,which was followed by a significantly cooling from the EA to GS *** the process of exhumation,UHP eclogites witnessed a series of events involving fluid influx,resulting in the formation of hydrous minerals at different stages. The nature of fluids changed from K-rich at the HP stage to K-poor at the EA stage and then K-rich again at the GS stage.

Planetary nebulae （PNe） are good tracers of the stellar populations, chemical composition and dynamics of their host galaxies. This paper reports the discovery of new PNe in the outskirts of the Andromeda Galaxy （M31） with the Guoshoujing Telescope （GSJT, formerly named the Large Sky Area Multi-Object Fiber Spectroscopic Telescope-LAMOST） during its early commissioning phase. In total, 36 candidates selected from SDSS photometry are confirmed in terms of their PN nature, including 17 new discoveries and another 19 previously known emission line objects. Their positions, spectra, radial velocities and m5007 magnitudes are presented. We discuss the potential for detecting more PNe in M 31 with GSJT＇s multi-object spectroscopy and the related applications in studies of the dynamics and chemistry of M 31 and its assemblage history.

以新垦绿洲主干防护林树种俄罗斯杨(Populus russkii Jabl.)为研究对象,通过对A(膜侧细流沟灌,灌溉定额3 750m3/hm2,少量多次灌溉)和B(漫灌,灌溉定额7 500m3/hm2,隔月灌)灌溉方式下俄罗斯杨树干液流、当年生枝条水势(ψs)以及叶片光合特征的同步监测,结合气象因子数据,分析比较2种灌溉方式下的俄罗斯杨水分生理特征。结果表明:B方式下俄罗斯杨树干液流速度与A方式比较有所降低,日均下降4.7%,但差异未达到显著水平(Sig.>0.10);2种灌溉方式下俄罗斯杨当年生枝条水势没有通过差异显著性检验(Sig.>0.142);A方式下的俄罗斯杨叶片净光合速率(Pn)、气孔导度(Gs)、瞬时蒸腾速率(Tr)、水分利用效率(WUE)均高于B方式的。综合分析认为,A方式节水效果显著,能够满足研究区俄罗斯杨生长的水分需求,过度灌溉会对俄罗斯杨产生不利影响;植物液流、水势等水分生理指标可做作调控和节水灌溉的科学依据。

＜正＞The importance of the inhibitory neurotransmitter γ-aminobutyric acid （GABA ） in certain neurological and psychiatric disorders has become generally accepted. The research of γ-peptide which is consisted with GABA is beneficial in the aspects of our understanding of life. The preparations of （1R,3S）-1 and （1S,3R）-1 were reported. However, practical methods for preparation of enantiopure trans-1 and cis-2 are very few. Here, we synthesized four enantiomers of optically pure 3-aminocyclohexanecarboxylic acid （1） and two enantiomers of optically pure cis-5-amino-3-cyclohexenecarboxylic acid （2） by the resolution.
