芥毛 的英文怎麼說
中文拼音 [jièmáo]-
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細胞，在擬南芥中表皮毛通常分佈在葉、莖、花萼上，它是植物體抵禦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
對其進行缺失突變，構建5個缺失表達載體轉基因擬南芥，葉片gus定量測定分析表明- 300bp ? - 1bp序列就可以指導gus基因在表皮毛細胞中特異表達，說明這段序列可能含有指導此啟動子在擬南芥表皮毛細胞進行特異表達的核心序列。H2o2 was cytochemically detected in the cells of epidermal hair and the cell wall of vascular parenchyma cell. cat and apx were the two major h2o2 - scavenging enzymes in plants. when seedlings of arabidopsis thaliana were treated by vd - toxin, the activity of cat and cat3 mrna level were decreased after sa treatment
外源sa 、 no供體處理擬南芥幼苗均能誘導h _ 2o _ 2的積累， no供體的誘導作用最強； no合酶抑制劑處理則未表現出h _ 2o _ 2含量的增強： h _ 2o _ 2的積累部位主要在葉片的表皮毛和維管束組織。Very true, said the duchess : flamingoes and mustard both bite. and the moral of that is - " birds of a feather flock together.
