WebMar 2, 2024 · The engineered TAS DNA acts as a transgene and, when introduced in plants, gives rise to syn-tasiRNA primary transcript (pri-syn-tasiRNA), which eventually spawns phased syn-tasiRNA duplexes of 21 base pairs in the usual tasiRNA biogenesis pathway. When TAS1 precursor is used, miR173/AGO1 complex acts an initiating slicer. Trans-acting siRNA (abbreviated "ta-siRNA" or "tasiRNA") are a class of small interfering RNA (siRNA) that repress gene expression through post-transcriptional gene silencing in land plants.
