Table 2

Summarized results of Tajima's [18] test of relative evolution of Brachypodium chloroplast genes compared with those of wheat, rice, and maize. The P value of genes that evolve at significantly different rates in Brachypodium is shown for each gene and species comparison. When P < 0.05, indicating that rates are significantly different, the species with the highest rate of evolution is shown in parenthesis. B: Brachypodium, W: wheat, R: rice, M: maize.
