natural mutation meaning in English
自然突变
Examples
- Sequence analysis showed that , this fragment has a homology of 99 % to the previously reported choe from rhodococcus equi . after cloning and subcloning and three identical fragments were obtained from three independent pcr , lacking three continual bases ( ttc , encoding the pheamino acid ) compared with choe , thus it can be assumed that the new fragment , designated as choew , and choe belong to the same gene family , even it might be the natural mutation of choe
对片段进行克隆、亚克隆之后测序分析，发现与已克隆的来源于马红球菌的胆固醇氧化酶基因cboe有99的同源性；并且三次独立的pcr均得到相同的片段，所克隆的基因序列与choe相比，连续缺失三个碱基( ttc ) ，即相应的氨基酸序列缺失一个氨基酸( phe ) ，因此判断所克隆的基因片段与choe属同一基因家族或原有基因的天然突变体，命名为choew 。 - The employees of the patent office and of the state variety commission have no right to file applications for plant varieties or to be mentioned as co - authors for the period of their labor relations with these state authorities and for three years after the termination of these relations , excluding the cases when the variety is a result of natural mutations , established during the examination as to substance , as per article 38 , paragraphs 1 and 2
6专利局与国家植物品种委员会的员工，在与这些政府机关存有劳资关系的期间或在此等关系终止后的三年内，无权提出植物品种的申请或被列为共同原创人，但如为依第38条第1和2项规定，于实质审查期间确定属于自然突变结果的品种，不在此限。 - In this study , systems of rapid propagation of the cultivars such as d . zingiberensis , d . panthaica and d . composite were setup to find the best way to meet the need of producing , and to establish the base of introduction , breeding and cultivar improvement of foreign dioscorea with high diosgenin ; in addition , there are two strategies to obtain polyploids combining with chromosome engineering : screeding natural mutations and mutation breeding were carred out on d . zmgiberensis . exploratively studies were done on rapid propagation of the three dioscorea plants . the result showed : explants of d . pathaica obtained the appreciate propagation efficency on ms + ba1 . 0mg / l + naa0 . 1mg / l , ms basic medium containing 6 . 0mg - 1 ba , l . 0mg - 1 kt and sucrose at 30gl - 1 or 60g1 - 1 was the appreciate medium for microtuberization
三种薯蓣属植物离体再生体系培养条件的探索试验结果表明：黄山药外植体适宜的增殖培养基为ms + ba1 . 0mg / l + naa0 . 1mg / l ，微型块茎诱导为ms + ba6 . 0mg / l + kt1 . 0mg / l + 3蔗糖，高浓度的蔗糖含量( 6 )能提高微型薯蓣的诱导率，但对其诱导起关键作用的还是ba的浓度；菊叶薯蓣增殖效果较好的培养基为ms + ba1 . 0mg / l ，以ms培养基为诱导微型薯蓣的最佳选择，诱导率可达50 ；盾叶薯蓣最适宜的增殖培养基为ms + ba2 . 0mg / l ，在诱导微型薯蓣的实验中发现，当ba浓度为6 . 0mg / l和8 . 0mg / l时， 15d左右节间处膨大形成绿色圆球状小块，但继续培养其上则开始分化芽。
