A full-length cDNA sequence encoding methionine sulfoxide reductase （MSR） from mulberry,which we designated MMSR was cloned based on mulberry expressed sequence tags （ESTs）.Sequence analysis showed that the MMSR is 810 base pairs in length,encoding 194 amino acids with a predicted molecular weight of 21.60KD and an isoelectric point of *** expression levels of MMSR at different developmental stages in mulberry leaves and flowers and in different tissues were *** results showed that MMSR transcripts were most abundantly expressed in the bud,and the expression level of the mRNA could be increased significantly under hypothermia,arid,and NaCl stress conditions compared to the normal growth *** is to help understand a molecular basis for signal transduction mechanism underlying the stress response in mulberry.

According to the characteristics of groundwater in arid area,this paper proposes DRAV model for groundwater vulnerability assessment,where D is groundwater depth,R is the net recharge of aquifer,A is the aquifer characteristics,and V is the lithology of vadose *** a case study,the paper assesses the vulnerability of pore phreatic water in Tarim Basin of Xinjiang,china by using the DRAV *** results indicate that the areas of phreatic water with vulnerability index ranges of 2-4,4-6,6-8 and>8 accounting for 10.1,80.4,9.2 and 0.2%of the total plain area of the Tarim Basin respectively, and the areas with the latter two vulnerability ranges (6-8 and>8)are mainly located in the irrigation districts with thin soil layer(20-30 cm thick surface soil of vadose zone,mainly with underlying sandy gravel)and with silty and fine sand *** vadose zone generally lacks sandy loam and clayey soil and has larger recharge by infiltration of irrigation water.

The 3D FEM numerical simulation on multi-action precision cold forging technology of universal joint cross and differential spider is done in this article using DEFORM Software, a commercial computer aided engineering software specializing in forming and heat treatment simulation technology, and suitable for cold, warm and hot forging process. The material flow properties, the dynamic variation of stress and strain in the process of deformation and the load-stroke curve have also been achieved. A good consistency is exhibited between simulation results and practical data. Based on the DEFORM simulation results, the optimized procedure has been found for forging a universal joint cross. What should be emphasized here is that a better understanding of practical forging characters and the environmental factors can greatly improve the simulation accuracy thus make the simulation results more reliable.

获得与经济性状相关的分子标记或基因是开展该性状分子育种的先决条件。本文利用300个微卫星标记检测了以柏氏鲤和荷包红鲤抗寒品系杂交F2代1个家系、92个个体的基因型,回归分析了其体长、体厚、体高和体重4种经济性状的GLM单标记。Permutation检验结果显示:有23个标记分别与体长、体厚、体高和体重具有显著相关性(P<0.05),其中,HLJ44、HLJE28、HLJ1148、HLJ1329、HLJ464与这4种性状极显著相关(P<0.01)。对同一标记不同基因型之间进行了多重比较,找到了与这4种性状相关的基因型。此研究还发现75个微卫星标记发生了偏分离,其中11个偏分离标记与性状显著相关,偏分离指数分析表明,基因型的偏分离可能与性状的选择压力和选择方式有关。本研究获得的与鲤4种性状相关的标记及基因型,为鲤的分子标记辅助育种(MAS)和生长性状的遗传机制研究提供了有效的依据。

从生态学的角度,把泥石流等山地灾害作为生态(自然)-社会-经济复合生态系统中一个特殊的组分———'灾害环境'来看待,由此对泥石流灾害防治的认识和措施体系也不是片面的、机械的'就灾论灾,就灾治灾',而是认为:只有通过恢复和重建泥石流流域生态(自然)-社会-经济复合系统的稳定性、协调性和可持续发展方能实现泥石流灾害防治的长期目标,这较以往对泥石流的认识,赋予了更多的生态学内涵。将生态、经济功能分区方法用于泥石流流域的研究和治理中,并对划分的各生态、经济区提出了关键的生态调控措施和产业配置。

The paper makes some analyses on 11 trace elements in the Milanggouwan stratigraphical section in the Salawusu River valley, which is regarded as a prototype geology-palaeoclimate record since 150 ka BP. The results show that the content and variation of trace elements has experienced remarkably regular changes in the pace with coarse and fine sedimentary cycles of palaeo-aeolian sands to its overlying fluvio-lacustrine facies or/and palaeosols. The trace elements with chemical properties of relatively active (V, Sr, Cu, Ni, As) and relatively stable (P, Pb, Rb, Mn, Nb, Zr) are a manifestation of the corresponding 27 changeable cycles between peak and valley values, appearing a multi-fiuctuational process line of relative gathering and migration since then. The low numerical value distribution of these two types of trace elements in the aeolian sand facies represents erosion and accumulation under wind force during the cold-dry climate. Whereas their enrichments in both fluvio-lacustrine facies and palaeosols are related to the valley’s special low-lying physiognomic position between the Ordos Plateau and the Loess Plateau under the warm and humid climate conditions. The above relatively migrated and gathered change of the trace elements is the result of 27 climatic cycles of cold-dry and warm-humid, which is probably caused by repeated alternations of winter monsoon and summer monsoon in the Mu Us Sandy Land influenced by the climate vicissitudes in northern hemisphere during glacial and interglacial periods since 150 ka BP.
