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.

Famous quotes containing the words presence and/or plants:
“Whatever is felt upon the page without being specifically named there—that, one might say, is created. It is the inexplicable presence of the thing not named, of the overtone divined by the ear but not heard by it, the verbal mood, the emotional aura of the fact or the thing or the deed, that gives high quality to the novel or the drama, as well as to poetry itself.”
—Willa Cather (1873–1947)
“Probably if our lives were more conformed to nature, we should not need to defend ourselves against her heats and colds, but find her our constant nurse and friend, as do plants and quadrupeds.”
—Henry David Thoreau (1817–1862)
