| 5. | In this study , lexa mutant of deinococcus radiodurans xe has been successfully constructed . the survival curve of this strain was measured using colony formation assay after treatment with different doses of radiation and different times of mmc 本研究利用已构建的抗辐射菌lexa基因突变体菌株xe ,经受不同剂量射线照射和不同时间的mmc作用,平板菌落计数,绘制存活曲线。 |
| 6. | The expression of lexa protein in the iptg - induced jm109 ( pza172 ) was checked by sds - page , and the survival curve of this strain was measured using colony formation assay after treatment with different doses of radiation and different concentrations of mmc 应用电穿孔技术将携带有抗辐射菌lexa基因的重组质粒pza172转入大肠杆菌jm109 ,其启动子为lacz ,用iptg诱导, sds - page凝胶电泳检测lexa蛋白的表达。 |
| 7. | 2 , the survival curves of populations of e . chloranthoides in jigong mountain and dongwenquan are diagonal , which indicates that the individuals of each age grade within the two populations possesses the roughly identical death rate and the populations belong to the stable ones , while the survival curve of population in beiwenquan is concave , which shows that the population belongs to the increase one 2 、种群存活率曲线表明,鸡公山和东温泉的缙云卫矛种群存活率均呈对角线型,说明这两个种群属于稳定型,而北温泉种群的存活率曲线呈凹型,属于增长型种群。 |
| 8. | When compared with kds301 ( lexa + ) , xe ( lexa - ) cells showed quite similar levels of survival curve to y - irradiation and mmc , indicating lexa gene had no effect on radiation resistance of deinococcus radiodurans . deinococcus radiodurans " lexa had no revelance with its extremely radioresistance . the recombinant plasmid pza172 was constructed by cloning the lexa gene of deinococcus radiodurans into the vector plasmid puc19 in the downstream of lacz promoter 对lexa基因突变体xe的研究表明,其辐射抗性与lexa基因野生型的抗辐射菌kd8301相近,存活曲线上均显示有一个宽大的肩区,结果发现lexa基因的突变并没有改变抗辐射菌的独特抗性,说明lexa基因与辐射抗性无关。 |
| 9. | The research can offer some important references to the population ecology of endangerous plant , too . based on the dates of two different circumstances , two standard life tables of form . taais chinensis var . mcarei population are founded by mathematical technique according to premising with " space deducing time " , and the curves of survival rate , mortality rate and killing power were drew . the results showed both of the survival curves of population appeared to be a type of deevey - iii and the high mortality of seeding is one of the important reasons which caused taxus chinensis var . mairei to be endangered , which badly limited the enlargement of form . taxus chinensis var . mcarei population 由于南方红豆杉无解析木,因而以“空间推时间” 、 “横向导纵向”方法,将林林依胸径大小分级,以立木级结构代表年龄结构,采用分段匀滑技术,对两个不同生境的南方红豆杉种群编制特定时间生命表,绘制存活曲线,结果表明不同生境的南方红豆杉种群的存活曲线均趋于deevey -型,两地差异较小,幼苗死亡率极高,不同生境的幼苗死亡率均达到96以上。 |
