avirulent meaning in English
adj.
无毒性的。
Examples
- Want security , avirulent , without remain or little remain
要安全,无毒,无残留或少残留 - Now many laboratories have used avirulent strains of s . typhimurium to deliver h . pylori antigens as a way of stimulating an immune response to those determinants
以鼠伤寒沙门氏菌标准株基因组dna作为模板，采用pcr的方法克隆了鼠伤寒沙门氏菌asd基因，经序列分析与文献报道一致。 - One of these pr genes , pr - la , responds not only to avirulent pathogen , but also to some chemicals , such as sa ( salicylic acid ) and bth ( benzothiadiazole ) etc . , and the responding ability to the inducers is controlled by its promoter
其中一个pr基因pr - 1a ，不仅受病原菌诱导，而且受一些化学剂如sa 、 bth等化学剂的诱导，其诱导应答由其启动子控制，因此pr - 1a启动子可以应用于植物化学诱导系统中。 - Most of plants , when attacked by avirulent pathogens , usually produce a hypersensitive response ( hr ) at the locus attacked and develop a systemic acquired resistance ( sar ) throughout entire plant by expressing a set of defense genes including pathogenesis - related ( pr ) genes
植物受到病原菌侵染后，感染部位产生过敏性坏死反应，在其它部位产生系统获得性抗性并伴随抗性基因包括病程相关蛋白( pathogen - relatedprotein )基因的表达。 - Finally , avirulent and virulent plant , bacteria of pseudomonas solanaceanim was investigated by chromatography . the result showed that there are two peaks when both bacteria was eluted , but their peak area ratio was quite different . when virulent bacteria was subject to chromatography after vibration by ultrasonic wave , both chromatographial behaviors of both avirulent and virulent pseudomonas solanaceanim were same basically , which showed a equilibrial peak and a eluting one
最后，表征了植物病原菌? ?青枯菌的强、弱致病菌株，结果显示强、弱菌都有两个洗脱峰，但峰面积比例有明显的差异，强弱致病菌株经振荡后，其色谱行为基本相似，表现为一个穿透峰和一个洗脱峰。
