Micro-RNAs (miRNAs) are regulatory molecules that mediate effects by interacting with
messenger RNA (mRNA) targets. Here we show that Arabidopsis thaliana miRNA 39 (also
known as miR171), a 21-ribonucleotide species that accumulates predominantly in inflorescence
tissues, is produced from an intergenic region in chromosome III and functionally interacts with
mRNA targets encoding several members of the Scarecrow-like (SCL) family of putative
transcription factors. miRNA 39 is complementary to an internal region of three SCL mRNAs.
The interaction results in specific cleavage of target mRNA within the region of complementarity,
indicating that this class of miRNA functions like small interfering RNA associated with RNA
silencing to guide sequence-specific cleavage in a developmentally controlled manner.

Well, the science threads wouldn't be dying if they all referred to cleavage.

Cleavage of Scarecrow-like mRNA targets...

Scarecrow cleavage -- better than nothing, I guess.....
