ABSTRACT:Objective To study the role of adaptor protein Dok6 in neurite outgrowth in PC12 cells.

目的 探讨胞浆接头蛋白Dok6对PC12细胞突起生长的影响。

Therefore, the lotus leaf fern Adiantum mainly in the growth of other plants rarely Uncovered Rock steep slopes or cliffs, these habitats and soil glare and often subjected to drought stress and thus not conducive to update the population and survival.

因此,荷叶铁线蕨主要分布在其它植物很少生长的陡坡裸岩或峭壁上,这些生境土壤瘠薄且经常遭受强光和干旱胁迫,从而不利于种群更新和生存。

Susceptibility of paddy rice to penoxsulam in seed germination and influence of temperature on it were conducted by the method of Agar-agar bed.

采用琼脂床法种子萌发试验研究了五氟磺草胺对不同品种水稻种子萌发及幼苗生长的影响。

Seeds of Ailanthus altissima Swingle were treated with 60Co γ-rays at the doses of 0, 30, 50, 75, 100, 150 and 200Gy, the effects of irradiation on seed germination and seedling growth were studied. The results showed that irradiation inhibited germination, and decreased the survival rate and the growth of plants.

以椿树种子为材料,用60Coγ射线进行了0、30、50、75、100、150和200Gy辐照处理,研究辐照对椿树种子发芽及幼苗生长的影响,以期获得耐盐突变体。

The resulting strain, designated YES2MTM1, was transformed with a yeast genomic library. Transformants lost the plasmid overexpressing MTM1 after 5-FOA treatment. Yeast strains able to grow on nonfermentable carbon source with MTM1 deletion and overexpression of some DNA fragments were picked up and candidate suppressor genes were identified. Overexpression of five genes were identified to be able to rescue the growth defect on nonfermentable carbon source. The study will provide reference for MTM1 gene function and screening for suppressor of genes whose deletion result in irreversible damage.

为了避免MTM1缺失造成的不可逆损伤,在野生型酵母中先转入带有MTM1 基因的质粒,再敲除染色体上的MTM1 基因,随后转入基因组文库,再利用药物5-氟乳清酸(5-FOA)迫使细胞丢失表达MTM1基因的外源质粒,再筛选能在非发酵培养基上生长的转化子,通过这种方法筛选发现,POR2等5个基因的过表达可以挽救MTM1 基因缺失造成的非发酵培养基上的生长缺陷,为深入了解MTM1基因的功能提供了线索,对筛选其他造成不可逆损伤的突变基因的抑制基因提供了一条可行的研究思路。

Use a good quality liquid or water soluble fertilizer with a formulation low in copper.(High amounts of copper are toxic to bromeliads.) We recommend 10-5-5 plant food. Normally dilute the suggested dosage to 1/4 strength. Fertilizing is not absolutely necessary to survival, but will increase the growth and vigor of your plants and their blooms.

用高质量的液态或水容性的肥料,要求使这些肥料中的铜含量必须非常的低(铜含量过高会毒害到铁兰),我们推荐10:5:5的肥料,正常的稀释浓度使1/4茶匙肥料用水一加仑,肥料并不是植株生长的唯一要素,但是却可以加速植株的生长速度和增加开花量。

Our study rules out the effect of strain and composition alloying as the main factor of peak splitting. We attributed it to the existence of large amount of non-stoichiometry part in GaN/Si grown by MBE. A direct proof has been observed by HRTEM, which shows that the propagation of dislocations in the underlying layers could be blocked by using periodic AlN/GaN structure.

用三轴晶高分辨X射线衍射研究了Si(111)上生长的GaN中的应变组分问题,我们发现GaN的对称(0002)及非对称(10-12)峰在三轴晶配置下的ω-2θ扫描曲线都会发生劈裂,我们排除了应力和合金化的因素,认为在MBE方法生长的Si(111)上GaN外延层中存在一个占较大比例的稍微偏离化学配比的部分。
