Amplification profiles of Tic40 genes from three diploid Brassica spp. Seven primer combinations, 3L/5R, 6L/8R, 8L/10R, 10L/12R, 12L/14R1, 8L/14R2, and 6L/14R1, were used to amplify DNA from genotypes of B. oleracea (T14, CGN06903, and CGN18458, T9), B. rapa (R7, CGN06832, CGN13925, and Chiffu), B. nigra (CGN06620, CGN06625, and CGN06630), and A. thaliana (Columbia). For 6L/14R1, the amplification profile is not shown because of the low resolution for large amplified fragments (about 1,500 bp).
