Welcome to my sandbox.
Here is where I practice making things bold and adding hyperlinks.
Biosynthesis
editTa-siRNAs arise from non coding transcripts through miRNA guided cleavage and conversion to double stranded RNA by the RNA-dependent RNA polymerase RDR6 and suppressor of gene silencing 3 (SGS3).[1] The resulting dsRNA is further processed by dicer-like enzyme 4 (DCL4) to produce a phased array of 21-nt siRNAs.[2][3]

Presence of ta-siRNAs
editThe presence of ta-siRNAs was originally detected in the flowering plant Arabidopsis [3]. Evidence of ta-siRNAs has also been found in the moss Physcomitrella patens [1], maize [4], and a strain of Oryza sativa rice. [5][4]
