Welcome to my sandbox.

Here is where I practice making things bold and adding hyperlinks.

Biosynthesis
Ta-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). The resulting dsRNA is further processed by dicer-like enzyme 4 (DCL4) to produce a phased array of 21-nt siRNAs.

Presence of ta-siRNAs
The presence of ta-siRNAs was originally detected in the flowering plant Arabidopsis. Evidence of ta-siRNAs has also been found in the moss Physcomitrella patens, maize , and a strain of Oryza sativa rice.
