Consensus sequences for the repeated hairpin structure in the _trnY_-trnE IGS region.

(A) The most common consensus 19 bp sequences and frequencies were as indicated on the hairpin structure. Positions 6, 7, 8, 9, and 14 were invariable and positions 10, 11, and 12 were the most variable sites. (B) Consensus sequences were derived from the 66 repeats of Asian E. arvense, the 73 repeats of American E. arvense, the 63 repeats of E. ramosissimum, and the 71 repeats of E. hyemale.
