我們將外源基因成功地導入藍豬耳,為利用轉基因的手段研究被子植物受精和胚囊發育打下基礎。The mechanisms of gene silencing include copy numbers and configuration of transgene, integration sites in plant and transcription of transgene, etc
基因沉默的機制是多方面的,包括轉基因的拷貝數和構型、在植物上的整合位點、轉基因的轉錄水平等。In the study of floral - dip method, flowering inflorescences of oilseed rape growing in field are immersed in floral - dip solution resuspended with cultured agrobacterium tumefaciens lba4404 or eha105, resided binary plasmid pbi121
在油菜花序浸泡法( noraldip )轉基因的研究中,用含雙元載體及報告基因的農桿菌在生產大田直接浸染正在開放的油菜花朵。To investigate the best period of transformation, different flowering stages including before, after and pollination were chosen to do floral - dip
分別處理開花授粉前、開花授粉時、開花授粉后的花序3 , 600 、 12 , 200 、 800個,期望發現油菜大田轉基因的最佳時期。Tobacco and its product - determination of genetically modified organism
煙草及煙草製品轉基因的測定To broaden our knowledge about regulatory molecules involved in stress response, we cloned the dreb1c from arabidopsis, and characterized its salt tolerance in transgenic research first. the flowing results were obtained : 1. the dreb1c full length was cloned from arabidopsis genome by pcr, and was inserted into pgem - t - easy vector
為了拓寬對參與植物脅迫應答的調控分子的認識,本論文從dreb1c的克隆著手,以擬南芥為材料,通過轉基因的方法,首次研究了dreb1c這種erebp / ap2類蛋白對植物耐鹽性的的影響,研究結果如下: 1Our results provided direct evidence that pf40 gene play a role in the tissue development, with knockout this gene the lateral buds were not visible. the plant hormones auxin and cytokinin appear to play a major role in controlling this process, therefore, the concertrition of auxin and cytokinin was measured, however, the concentration of the two hormone was variation a little in transgenic plants, but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type. furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants, results showed the pf40 could change both xylary fibers and vessel
進一步的實驗發現pf40基因會影響植物側芽發育的早期,即pf40基因作用在側芽形成與發育的早期。對轉基因穀子的組織切片的分析還表明pf40基因引起不同形式的轉基因穀子的維管組織的發育的差異,轉化正義載體穀子的木質部變多,維管系統增多,而反義或干擾的轉基因穀子的木質部數量變少,木質部分化異常。從轉基因的結果可見pf40基因可以減弱植物的頂端優勢,這種作用是通過改變植物體內激素的含量實現的。He said one example is genetically changed crops that will grow in extreme temperature, dry conditions or poor soil

通過轉基因的結果與軟體的分析,推測pf40基因的作用可能是通過改變植物維管組織的發育從而調控一些離子的運輸或吸收進一步激活一些激素的表達或者激素受體,最終影響了植物的生長模式。分享友人
