wild-type strainの例文
- Plant assay was performed with the wild - type strain gx201 , the mutant strain gx217 and the function recovered strain rgx217 . the results indicate that the mutant strain gx217 showed a day delay in nodulation time and its abilities of nodule formation efficiency and competitive nodulation were apparently decreased compared with the parental strain gx201 respectively
- The morphological , physiological , biochemical and genetic diversities between bacillus thuringiensis wild - type strain ybt - 1463 and its plasmid - free mutant bmb171 was comparatively studied . it showed that the plasmid - free mutant strain bmb171 lost the ability to form the parasporal crystal , but there was on obvious diversities were observed on the sensitivity to 10 antibiotics , the utilization of 19 carbon sources and 12 nitrogen sources , as well as the growth properties between ybt - 1463 and bmb171 , whereas the electro - transformation frequencies of bmb171 were much higher than those of ybt - 1463 , respectively with 5 exogenous plasmids as the donor dnas
- There is no acrystalliferous derivative was screened after treating 4 . 5 g / ml ethidium bromide , but after elevating growth temperature of ybt - 1463 and other 8 bacillus thuringiensis parental strains to 42 , 9 acrystalliferous derivative were obtained . a series of partially plasmid - cured derivatives were further obtained from 3 acrystalliferous derivatives originated from wild - type strain ybt - 1463 by elevating temperature to 44
