Supplementary Figure 12: Average storage root yields of wild-type TME 204 (gray bars) and empty-vector controls (white bars) under field conditions across different confined field trials, harvested 12 months after planting.

For CFT 27 and CFT 30, n = 3 biologically independent plants; CFT 31, n = 9 (3 plants per replicate); CFT33, n = 8; CFT 36 and 37, n = 20 (5 plants per replicate). Box and whisker plots were constructed using the R software package The upper whisker extends from the hinge to the largest value no further than 1.5* IQR from the hinge (where IQR is the inter-quartile range, or distance between the first and third quartiles). The lower whisker extends from the hinge to the smallest value at most 1.5* IQR of the hinge. Data beyond the end of the whiskers are called “outlying” points and are plotted individually. Statistical tests were two-sided using Student’s t-test compared to non-transgenic control. *, ** and *** represent significance levels at p ≤ 0.05, p ≤ 0.01 and p ≤ 0.001 respectively.
