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。 -
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。 -
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。
