  • KanR plants contain the cosmic and KanS do not. Each line is derived from an independent transformation event. Expected ratios for KanR and KanS plants are 75:25 and 50:50, respectively, if the 18H1 cosmid complements the fis2 mutation. Control cross with C24 shows the segregation of fis2 without complementation. NA, not available.
