The structure of the title compound was identified by 1H , 13C, DEPT (distortionless enhancement by polarization transfer) and various two dimensional nuclear magnetic resonance spectroscopy, such as COSY (correlation spectroscopy), HSQC (heteronuclear correlation spectroscopy) and HMBC (heteronuclear multiple bond correlation spectroscopy).
利用普通1 H NMR ,1 3C NMR ,极化转移谱 (DEPT)以及同核相关谱 (COSY)、异核相关谱 (HSQC) ,特别是远程偶合谱 (HMBC)等多种核磁研究方法对新型的血管扩张药西尼地平的1 H、1 3C信号进行完全归属。
Through single hyphal-tip isolation,a heterokaryon,Ag149,was obtained,and its two different phenotypic segregants,Ag149-Ⅰ and Ag149-Ⅲ,were separated from the mutated sectors on colony of the heterokaryon.
采用银染mRNA差异显示技术 ,研究了棉花枯萎病菌异核体菌株 (Ag14 9)及其两个不同表型分离子(Ag14 9 Ⅰ和Ag14 9 Ⅲ )之间差异表达的基因 ,观察到在 3 0 0~ 70 0bp之间出现了 19个差异条带 ,经反向RNA印迹 ,证实其中 2条差异带为阳性 :编号为C6的差异条带在Ag14 9和Ag14 9 Ⅰ菌株中呈高表达 ,而编号为G5的差异条带在菌株Ag14 9和Ag14 9 Ⅲ中呈高表达。
Then,those strains were mutated,re-isolated,and identified into 7 nit mutant strains which were veg- etably compatible and form heterokaryon.
从蝉拟青霉T-1上分离获得的6个单孢子菌株,经过诱发、分离、鉴定,保存了7个nit突变株,并通过营养亲和试验筛选出蝉拟青霉异核体菌株55-57、56-57、58-57,以及稳定性好的亲本菌株55、56、57、58,比较分析各菌株对蚜虫的致病力以及胞外多糖的含量,数据显示55-57、56-57、58-57菌株的LT50、LT90较低,而且它们的胞外多糖含量稳定且高于55、56、57、58各亲本菌株。
Two segregants (Agl49- Ⅰ and Ag149-Ⅲ) were isolated from a heterokaryon of Fusarium oxysporum f.
