Fig. 1. MiR159 and GAMYB mRNA target sequences are evolutionarily conserved. (A) Sequence similarity between three Arabidopsis miR159 isoforms. The nucleotide mismatches are in grey. (B) Sequence similarity between miR159a and internal sequences of putative target genes. Nucleotide mismatches between the internal sequences and miR159a are in grey, and the total number of mismatches is indicated after each sequence. Function and accession number for each putative target is indicated on the right. (C) Location of the complementary sequence between GAMYB genes and miR159. Regions of similarity between Arabidopsis and H. vulgare GAMYB genes are shown in black. The region of sequence that is complementary between miR159a and the GAMYB genes is shown in grey.
