miR156 functions in the induction of flowering by suppressing the transcripts of SQUAMOSA-PROMOTER BINDING LIKE (SPL) transcription factors gene family. It was suggested that the loading into ARGONAUTE1 and ARGONAUTE5 is required for miR156 functionality in Arabidopsis thaliana. In plants the precursor sequences may be longer, and the carpel factory (caf) enzyme appears to be involved in processing.
miR156 functions in promoting flowering by suppressing SPL transcription factor genes. It was proposed that miR156 needs to associate with ARGONAUTE1 and ARGONAUTE5 to function correctly in Arabidopsis thaliana. In plants, precursor sequences may be longer, and the carpel factory (caf) enzyme is involved in processing.
