GhmiR156-<i>GhSPL2</i> Module Regulates Anthocyanin Biosynthesis of Ray Florets in <i>Gerbera hybrida</i>.

ABSTRACT: Anthocyanins, biosynthesized through the flavonoid pathway, critically determine floral coloration and ornamental value in plants. While floral development has been extensively studied in Gerbera hybrida, the microRNA-mediated regulation of anthocyanin biosynthesis remains unclear. In this study, we identified and characterized the precursor of gerbera microRNA156 (GhmiR156), which exhibits a typical stem-loop secondary structure. The mature GhmiR156 sequence shows 93.65% similarity with miR156 from other plants. Through target prediction analysis, we identified five potential target genes of GhmiR156, all encoding SQUAMOSA Promoter-Binding Protein-Like (SPL) transcription factors. Among these, the gene c35442.graph_c0, which shares the highest similarity with AtSPL2 in Arabi
