Fig. 7. Rescue of the ult1-1 mutant phenotype by an ULT2 transgene. (A) Floral organ number in wild-type Ler plants, ult1-1 plants and ult1-1 plants containing the d35S::ULT1 or d35S::ULT2 construct. Graph shows the mean number of organs in the first ten flowers of 10 plants (n=100 flowers), and the standard error is indicated. For the transgenic lines in the ult1-1 mutant background, the mean organ number was calculated from the first ten bolting T1 plants that did not show an overexpression phenotype. (B) Days to bolting after germination for Ler plants, ult1-1 plants and ult1-1 plants containing the d35S::ULT1 or d35S::ULT2 construct. The mean number of days to bolting was calculated from the same populations of plants that were used for the floral organ counts in (A) (n=10 plants), and the standard error is indicated.
