  1. The exon and intron length data for each gene in the table are arranged according to seven species of Agropyron Gaertn and two closely related species (ACPE, ACPL, AD, ADP, AS, AMV, ASP, ET, and EE). A single number indicates that the length of this region is consistent across all nine species; multiple numbers indicate that different species exhibit length variations in this region.2.2 Analysis of Codon Usage Bias and Interspersed Repeats.
