Fig. 3. MSI1 and MSI4/FVE are non-redundant. (A) MSI1 and MSI4/FVE expression profiles are strongly correlated. Data are based on measurements from 238 microarrays profiling Arabidopsis development (Schmid et al., 2005), which were processed using the GCRMA algorithm. The observed correlation between MSI1 and MSI4/FVE (Pearson correlation coefficient=0.92) was among the top 0.028 % of the highest values found in this data set. (B) Analysis of the flowering time of msi1-tap1 and fve plants in LD either without (-) or with (+) introduction of the construct 35S::MSI1. (C) Analysis of the flowering time of msi1-tap1, clf and clf msi1-tap1 double mutants in LD.
