  1. A genetic transformation model for the brown seaweed undaria pinnatifida has been primarily set up by using micro - particle bombardment as the method, female or male gametophytes as the gene recipients, hybridization as the regeneration route and chloramphenicol, hygromycin or basta as selective reagents

    本文從轉化受體、轉化方法、報告基因、再生途徑、篩選方法等方面對裙帶菜的遺傳轉化進行了研究。首先，分離並建立了裙帶菜雌雄配子體的無性繁殖系，進行了裙帶菜的不同再生途徑的研究。
  2. They contained an antisense constructed for the spruce gene encoding ccr ( cinnamoyl alcohol dehydrogenase ), an enzyme of monolignol synthesis. the antisense rna method is a technique for reducing the expression of a resident target gene. the transgenic sublines were produced by particle bombardment at the dept of forest genetics, swedish university of agricultural sciences

    本項目研究的目的就是採用瑞典農業大學構建的反義ccr基因轉導的挪威雲杉細胞愈傷組織，通過誘導產生再生植株，並檢測證實該基因是否表達及其它相關基因的表達狀況，為培育出低木質素的轉基因挪威雲杉新品種奠定物質和理論基礎。
  3. Charged particle bombardment

    帶電粒子轟擊
  4. The first two reports of soybean transformation used two very different methods to transform soybean : hinchee et al ( 1988 ) used agrobacterium - mediated transformation of cotyledonary nodes while mccabe et al ( 1988 ) used particle bombardment of shoot meristems. soybean transformation reports following these initial papers have been limited and the transformation efficiency of soybean has remained low, the reason is that cells that are regeneration - competent must also be accessible and transformation - competent

    目前應用於大豆遺傳轉化的方法主要有根癌農桿菌介導法，基因槍法，超聲波輔助農桿菌法，真空抽濾法，花山東師范大學碩士學位論文粉管導人法等，但其中獲得廣泛應用的只有根癌農桿菌介導法和基因槍法，但是這兩種方法在應用中也有一定的局限性。
  5. The chimeric gene was transformed into rice calli by particle bombardment. many resistance calli were obtained, and gus activity was detected. in order to confirm the causality of the mutant phenotype and osdd2 gene, we took an approach of functional knockout ofosdd2 gene, with the method rnai ( rna interference )

    為了進一步驗證本基因的功能，利用獲得的包含wrky保守域的cdna片斷構建了可能產生rna干涉（ rnainterference ， rnai ）的載體，利用農桿菌轉化法轉化水稻，目前已經獲得一批轉基因苗。
  6. In order to breed maize dwarf mosaic disease ? esistance maize species, the pap gene was introduced into maize inbred strains and hybrid strains mediated by pollen and particle bombardment, 10 transgenic maize plants were achieved and the pap gene was indeed integrated into the maize genome by analysis of molecular biotechnological methods. the pap gene in one of the transgenic maize plants had been transcription and translated, the ability of the virus resistance is undergoing

    為了解決玉米矮花葉病害的防治問題，採用花粉介導法及基因槍法將pap基因分別導入玉米的雜交種及自交系，獲得了10株轉基因玉米， pcr及southern - blot檢測結果表明pap基因已經整合到了玉米基因組中，並且其中有一株pap基因已經得到了表達，病毒抗性鑒定表明轉基因玉米能明顯推遲玉米矮花葉病害癥狀的表現。
  7. Strawberry calli were transformed by particle bombardment ( pds - 1000 / he gene gun ) with plasmid pby520 containing late embryogenesis abundant protein gene, lea3, from barley. lea3 gene was regulated by act i and pin ii, bar gene as a selected gene
