Figure 6.

Natural variation in ethanol yield among five Brachypodium distachyon accessions. Stems of fully senesced plants were ground and incubated for 3 days with Clostridium phytofermentans. Data are means ± SEM of three replicates; bars annotated with the same letter are not significantly different at P < 0.05 (Scheffé's test for multiple comparisons).
