青色鏈黴菌 的英文怎麼說
中文拼音 [qīngshǎiliànméijūn]
青色鏈黴菌
英文
streptomyces glaucus-
S. lividans mutant strains zx1 ( dnd cluster deleted ) and zx64 ( dnda disrupted ) had pleiotropic mutations including low mel expression and poor sporulation. it was speculated that dnda together with its downstream dna ( 2. 5kb ) might be involved in these two phenotypes because dnda together with its downstream dna could restore normal sporulation and mel expression to zx64, while dndb and dndc had no such effect because lai and la2 showed no obvious difference in these two phenotypes from wild type s. lividans 1326
另外通過比較這幾個突變株及野生型菌株在產孢和黑色素基因( mel )表達方面的差異,推測dnda及其下游區域與變鉛青鏈黴菌的產孢和刺激外源黑色素基因的表達有關,而dndb和dndc則與之無關,因為la1和la2在這兩種表型上與野生型菌株無明顯差異。Additionally, hau3r gene with it own promoter was cloned into high - copy plasmid pij653 and integrative plasmid pset152, respectively. transformants of s. lividans zx1 carrying these clones were infected with hau3, respectively, but the results shown that there was no significant correlation between the copy number of hau3r gene and the level of resistance to hau3
另外,將染色體來源的攜帶自身啟動子的hau3 ~ r基因分別克隆到高拷貝和低拷貝載體上並將其導入變鉛青鏈黴菌zx1 ,在實驗條件下未發現拷貝數與抗性水平間存在顯著相關性。
