tasiRNAs
TasiRNAs, or trans-acting small interfering RNAs, are a class of plant small RNAs derived from noncoding TAS transcripts. They are generated in a phased manner and act in trans to silence target mRNAs, often those that are not the source of the tasiRNAs themselves.
Biogenesis of tasiRNAs begins when the microRNA miR390 binds to conserved sites on TAS transcripts, guiding
The most studied tasiRNAs are those derived from TAS3 transcripts, which generate tasiRNAs targeting Auxin Response
Functionally, tasiRNAs contribute to plant development by coordinating organ formation, leaf morphology, meristem activity, and responses
