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.

Results: The atherosclerotic model was successfully established in rabbits. T1 WI, T2 WI and PDWI sequences scanning showed thickening of aortal wall and the plaque showed equal, high or low signal intensities, which was in good accordance with the pathological examination results. The atherosclerotic plaques were successfully detected and analyzed by MR and MR had higher accuracy than ultrasound examination.
