Summary
Encodes a microRNA that targets several MYB family members. MicroRNAs are regulatory RNAs with a mature length of ~21-nucleotides that are processed from hairpin precursors by Dicer-like enzymes. MicroRNAs can negatively regulate gene expression by attenuating translation or by directing mRNA cleavage.Mature sequence: UUUGGAUUGAAGGGAGCUCUU. Functions redundantly with MIR159A. Plants that are doubly mutated for MIR159AB have curled leaves and reduced stature.

    Title: ABI5 acts downstream of miR159 to delay vegetative phase change in Arabidopsis.
  2. PtrMYB012 transcripts are down-regulated by miR159 in poplar but not in Arabidopsis. Indeed, subsequent 5'-RACE analysis confirmed that PtrMYB012 transcripts are completely degraded in poplar, probably by miR159, but not in Arabidopsis. These results suggest that species-specific family members of miR159 are important for the regulation of normal growth and development in plants. [MYB012]
