trichomes meaning in English
香毛簇
Examples
- The effect of glandular trichomes may depend on the nature of the exudate .
具腺毛状体的影响依赖于分泌物的性质。 - Trichomes are unicellular or pluricellular outgrowths from the epidermis of leaves, shoots, and roots .
毛状体是叶片、枝条和根的皮层的单细胞或多细胞的外生物。 - The silicon and pod accumulated on the base of trichomes . the results of external experiment demonstrated that pod is essential for silica deposit , addition of omm , 0 . 5mm and 2mm hssio4 to reaction systems had no effect on the activity of pod
体外模拟结果显示pod是硅沉积的一个必需的催化物质，而硅酸在0mm0 . 5mm , 2mm ,浓度下，对pod活性无明显影响；但在5 ， 10mm浓度下，抑制pod活性。 - Trichomes are specialized epidermal cells , which are normally present on the leaves , stems , and sepals of arabidopsis . they are thought to provide a first line of defence against pests and pathogens , so the cloning and analysis of trichome - specific - promoter is of significance
表皮毛是特化的植物表皮细胞，在拟南芥中表皮毛通常分布在叶、茎、花萼上，它是植物体抵御外界侵害的第一道屏障。 - We clone a 1 . 3kb promoter sequence of the homologous gene in arabidopsis by pcr . this promoter is shown to direct the specific expression of the reporter gene , b - glucuronidase ( gus ) , in trichomes of arabidopsis . promoter deletion analysis reveal that the region from - 300 - - 1 bp is sufficient to direct trichome - specific expression
对其进行缺失突变，构建5个缺失表达载体转基因拟南芥，叶片gus定量测定分析表明- 300bp ? - 1bp序列就可以指导gus基因在表皮毛细胞中特异表达，说明这段序列可能含有指导此启动子在拟南芥表皮毛细胞进行特异表达的核心序列。
