Presence in Plants
In addition to being present in arabidopsis, evidence of ta-siRNAs has also been found in the moss Physcomitrella patens, maize, and a strain of Oryza sativa rice. The trans-acting short-interfering RNA-auxin response factor (tasiR-ARF) is an example of a ta-siRNA that has been shown to be present not only in arabidopsis, but in all of the previous examples. TasiR-ARF is responsible for regulating the signaling molecule Auxin. It does this by targeting the mRNA that encodes several of the Auxin Response Factor (ARF) genes for degradation.
