2. 藻絲。
adj. 形容詞 -chomic
  1. The anatomical and ultrastructural research in the cotyledon of antirrhinum majus indicated : cutin membrane and sparse epidermal trichome occurred on the surface of cotyledon. stomata protruded appreciably over the epidermis, the ratio of palisade mesophyll and spongy mesophyll was low, the previous evidence showed structural charecater of shade leaf

    通過對金魚草子葉的組織學和細胞學研究，發現其表皮角質膜薄，具稀疏表皮毛，氣孔略突出於表皮，柵欄組織與海綿組織比例小，故具有陰性葉的結構特徵。
  2. The purely mechanical effect of glandular trichome exudates is the entrapment and immobilization of small arthropods.

    具腺毛狀體分泌物的純機械作用是誘捕和粘住小的昆蟲。
  3. The collective trichome cover of a plant surface is called pubescence.

    植物表面聚集的毛狀物稱為柔毛。
  4. Toxicity was reduced when nicotiana trichome exudates were removed by various washing methods.

    當通過不同洗滌方法除去煙草屬毛狀體的分泌物時，毒力降低。
  5. This promoter may provide efficient bioengineering to enhance pest and pathogen resistance, and is of theoretical significance on the trichome molecular system

    此啟動子可用於基因工程提高植物體對外界侵害的抵抗力，對于研究表皮毛發育調控機理也有一定理論意義。
  6. 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。
  7. 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。
  8. Described here is the cloning and characterization of a new trichome - specific - promoter in arabidopsis. by ddrt ( differential display reverse transcription ) - pcr and reverse northern, a 280bp sequence is acquired from the epidermal in viciafaba, which is specially expressed in the epidermal. then using race, we abtain a 3. 0 kb gene segment including the 3 ' end full sequence and the 5 ' end partial sequence of the 280bp segment

    首先，我們利用差異顯示技術和反northern技術，以蠶豆葉肉細胞為對照，從蠶豆葉片表皮細胞中克隆出長280bp的新的表皮特異表達基因片段，再通過race技術獲得此基因片段的3 』端全序列和5 』端部分序列。
