Cleavage sites of miR6024 and two tasiRNAs in gene T-I2-3 . The 22 nt miR6024 has three mismatches with gene T-I2-3. The blocks of 21 nt (marked by underlines) show the tasiRNAs triggered by miR6024, and the 6th-14th tasiRNAs were omitted as indicated by “//”. The arrow in T-I2-3 matching the miR6024 sequence shows the cleavage site of miR6024, evidenced by RACE-PCR and degradome analysis. The arrows in the third (3′S3) and 15th (3′S15) tasiRNAs are most likely the cleavage sites of tasiRNAs.
