Figure 1

Results from greenhouse trials of transgenic plants. The constructs are denoted by the promoter used, except in the case of SPY genes. Dark bars show the maximum fractional rate improvement (best two transgenic events from best greenhouse experiment) compared to controls. Open bars show the mean fractional growth rate improvement for all transgenic events in that greenhose experiment. Brackets denote one standard error. A “*” above an open bar indicates statistically significant difference between the transgenic and control groups.
