Its overexpression resulted in a higher miR173 abundance (Table  2) and tasiRNA biogenesis (Figure  1) from TAS1 and TAS2 loci (Figure  3), which may degrade their PPR/ TPR target mRNAs, as reflected by the microarray data (Table  3). [score:5]

In addition to MIGS-miP1b transgenic plants, we also generated transgenic MIGS-miP1a/b plants by overexpressing their respective coding sequences fused to the miR173 target sequence. [score:5]
To study the flowering behavior of plants with reduced miP1a/b mRNA levels we used the microRNA -induced gene silencing (MIGS) technology [28] and overexpressed the sequences encoding the miP1a/b-specific carboxy terminal regions (for MIGS-miP1a and MIGS-miP1b) or the full-length coding sequences of both miP1a and miP1b fused to a miR173 -binding site (for MIGS-miP1ab). [score:3]
These fusion constructs are recognized by miR173, which elicits the production of trans-acting siRNAs (tasi -RNAs) that target then either miP1a or miP1b alone or miP1a and miP1b mRNA simultaneously. [score:3]

Using pssRNAMiner, we found that phased siRNAs from all four TAS loci targeted by miR173 could be detected. [score:3]
miR173 and miR390 (16 reads) that target TAS genes are also detectable which suggests activity of the tasiRNA pathway, where initial cleavage of the TAS transcripts by these miRNAs is required to initiate tasiRNA biogenesis. [score:3]

[score:1]

In this scenario, tasiRNA accumulation would be indirectly affected because tasiRNA biogenesis relies on miRNA -guided cleavage (miR173 targets TAS1 and TAS2 and miR390 targets TAS3) [45] (Figure 5B). [score:6]
The two miRNAs known to prime the synthesis of the tasiRNA precursors (miR173 for TAS1 and 2 and miR390 for TAS3) accumulate to a lower level in flowers from SINE expressing individuals (Col0-SB1.7(18)) compared to wild type (Col0). [score:2]
The accumulation of tasiRNA also was reduced in SB1 transgenic lines, presumably because tasiRNA production primarily relies on the action of DCL1-HYL1 -dependent miRNA miR173 and miR390 (Figure 5B). [score:1]
