Seed abortion rate of SmE mutants.

The fraction of aborted ovules relative to the total number of ovules in the siliques (n =  20) of the six different genotypes was calculated and plotted as a box-with-whiskers plot. The box spans over the 25^th to 75^th percentiles, the line inside the box represents the median, whiskers reach out to the minimal and maximal values in each dataset. A one-way ANOVA test with Tukey correction was performed after the removal of outliers using the ROUT method (Q =  1%). All statistical tests were run using GraphPad Prism. Letters represent significantly different (P <  0.05) groups.
