查询词典 nitrate

The nitrate non-utilizing mutantas an another added genetic marker was used to select the out-crossed perithecium from self-crossed perithecia. Seven crosses were tested in all, including cross between S×S, MR ×S, MR×MR,HR ×S, as well as HR ×MR. The results showed that no recombinant phenotype was found among all progeny of seven crosses. Progeny segregation of crosses between the parents with different sensitive levels (i.e. MR×S, HR×S,HR×MR) clearly fit a 1:1 ratio of two parental phenotypes, and no segregation was found in the crosses of S×S and MR × MR.
