猪瘟病毒通过网格蛋白介导的内吞途径入侵ST细胞
猪瘟病毒 入侵 网格蛋白 内体
2016/8/18
病毒入侵易感细胞是病毒建立感染的必要过程,猪瘟病毒如何入侵易感细胞尚未明确。笔者对猪瘟病毒入侵细胞与网格蛋白介导的内吞途径的关系进行了初步研究。通过利用抑制剂氯丙嗪和Dynasore及shRNA技术,对网格蛋白及动力蛋白功能进行抑制,干扰网格蛋白介导的内吞途径,发现猪瘟病毒的细胞入侵效率明显下降;通过利用内体酸化抑制剂NH4Cl及shRNA技术下调内体标志蛋白Rab5和Rab7的表达量,发现内体酸...

GPS Trimble JUNO ST was tested at 16 points under forest canopy. The measurements were done on three different dates of the growing seasons in 2007 and 2008. On each date, 4 recordings were measured i...
本试验旨在对分离自牦牛、猪和鸡的空肠弯曲杆菌(C.jejuni)主外膜蛋白基因(cmp)结构特点和基因序列型(ST)进行研究。共克隆分析了60株(牦牛15株、猪22株和鸡23株)空肠弯曲杆菌分离株cmp基因的完整编码框,构建进化树,并参照国外文献报道以核苷酸序列中的一个核苷酸不同,认为是不同的ST型为标准,进行序列分型。结果表明:60条cmp 基因有13个不同的长度,含有7~10个预测的表面暴露的...

水稻条斑花叶突变体生态st(t)的鉴定与遗传定位
条斑花叶
2009/12/21
利用EMS诱变育成优良籼型恢复系缙恢10号,从其后代中鉴定出一个白色条斑花叶突变体st(t),在三叶期开始表现白斑,拔节期白斑变为不规则线状,一直保持到成熟。突变体叶绿素含量明显下降,类胡萝卜素含量显著升高。透射电镜观察表明,突变体的绿色叶片部位与野生型相比,在细胞结构上无明显差异,叶绿体发育正常;突变体的白化部位细胞结构异常,质体内多含有积聚在一起的嗜锇小球,不能发育出正常叶绿体所具有的类囊体和...
