Analysis of the TAS3 gene and tasiR-ARF in rice. (A) OsTAS3a on chromosome 3 and OsTAS3b on chromosome 5, as marked in red; OsTAS3a-phased tasiR-ARFs were from the 5′D6(+) and 5′D7(+) positions and OsTAS3b-phased from the 5′D7(+) and 5′D8(+) positions. (B) Alignment of tasiR-ARFs in rice and Arabidopsis, shaded nucleotides indicating mismatches. (C) Complementarity of tasiR-ARF and OsARF3s. In OsmiR-ARF(390), Osta-siR2141 from OsTAS3a was used, three red asterisks between ta-siR2141* and ta-siR2141 indicating the introduced mismatches; red asterisks between the OsTAS3a ta-siR2141 and OsARF3-1 site A indicating matching of OstasiR-ARF and OsARF3s.
