Fig 5.

Increased growth and fecundity of F₂ crop–weed (Oryza sativa f. spontanea and Oryza sativa) hybrid progeny with the 5-enolpyruvoylshikimate-3-phosphate synthase (epsps) transgene in field experiments. The number of panicles (flowering shoots) and seeds per plant for each of the four crop–weed lineages are shown, with means and SE (n = 6). Closed columns indicate genetically engineered (GE) plants and open columns indicate non-GE plants. (a, c) Results from pure cultivation of either GE or non-GE plants in each plot (compared using t-tests with Bonferroni corrections); (b, d) results from mixed cultivation of GE and non-GE plants competing in the same plot (compared using paired t-tests with Bonferroni corrections). **, P < 0.01; ***, P < 0.001; see Table 2 for ANOVAs and Supporting Information Table S3 for a summary of these and other fitness-related traits.
