The entire functional dnd gene cluster was minimized to an 8 . 3kb insert in phz1904 , because phz1904 could complement the dnd phenotype of s . lividans mutant strain zx1 as well as streptomyces parvulus atcc12434 and streptomyces nanchangensis ns3226 , two naturally dnd - deficient streptomyces strains 將這個8 . 3kb的區域以整合形式導入無dnd表型的兩個異源宿( ? )中，均使它們獲得了dnd表型，表明這段8 . 3kb的區域包含了完整的異常修飾的功能。

Base on the successful expression of pks gene by cits857 controlled lambda promoter , an e . coli expression vector phz330 , an e . coli and streptomyces bi - functional vector phz1060 were constructed containing the dts857 - pr for inducible expression in both hosts . both vector 根據受cits857調控的p _ r能引導pks基因的成功表達，構建了大腸桿菌表達載體phz330以及在大腸桿菌和鏈霉菌兩種宿主中都能表達外源基因的雙功能表達載體phz1060 。

Using these vectors , expression of the pks gene was achieved both in streptomyces lividans and in e . coli in a heat - dependent manner , suggesting that the lambda promoter and temperature - sensitive lambda represser functioned in s . lividans as well as in e . coli 利用這些質粒在變鉛青鏈霉菌和大腸桿菌中均表達出pks蛋白，兩種宿主中的表達都是熱依賴的。暗示噬菌體啟動子和溫敏型阻遏物在變鉛青鏈霉菌和大腸桿菌中都具有功能。

A novel dna modification discovered in streptomyces lividans is different from dna methylation . this unusual modification causes wild type s . lividans dna sensitive to site - specific oxidative double - strand cleavage ( dnd phenotype , dna degradation ) 變鉛青鏈霉菌的dna異常修飾系統是一種不同于甲基化修飾的新型修飾系統，它可使變鉛青鏈霉菌dna在電泳時易遭到氧化雙鏈切割( dnd表型， dnadegradation ) ( zhouetal . , 1988 ) 。

Fr - 008 and streptomyces griseus imru3570 are two independently isolated producers for a similar heptaene macrolide antibiotic . comparative studies between the two producers at chemical and biological level are the main task of the present work , no obvious difference was observed on the hplc profiles 本文主要從化學和生物學兩個角度分析和比較了這兩個菌株的異同，并對抗生素的氨基海藻糖殘基基因進行了克隆嘗試。

14 out of 25 strains of biocontrol agent streptomyces showed chitinolytic activity by biological assay . these 14 strains of biocontrol agent streptomyces were detected for chitinase gene using pcr primers derived from the conservative sequence of 17 cloned chitinase genes from streptomyces 此方法相對于幾丁質酶的傳統生物學檢測，具有更好的準確性和靈敏性；而且與生物學檢測相比，使用分子檢測省時省力。

An internal segment of the whig gene of s . griseus was amplified from plzl through pcr . the 304bp dna fragment was inserted into the ecori / bamhi site of e . coli - streptomyces shuttle plasmid pkc1139 , generating pkc1139 : : a whig , named plz107 , for gene disruption Pcr法克隆whig基因內部304bp片段，連接到大腸桿菌-鏈霉菌穿梭質粒嚇0139 ，構建了基因陽壞用重組質粒賊q139 ： ：凸mg ，命名plz107 。

Streptomyces are mycelial multicellular soil actinomycetes in which adverse environmental conditions induce a developmental program involving complex morphological differentiation coordinated with synthesis of an enormous variety of interesting and useful secondary metabolites 鏈霉菌是絲狀多細胞土壤放線菌，土壤逆環境誘導鏈霉菌具有復雜形態分化生命周期，獲得合成大量有用次生代謝物能力。
