Transcriptome profiling provides preliminary molecular insights into adventitious bud formation in herbaceous peony (<i>Paeonia ×</i> ‘Coral Charm’)

Herbaceous peony is a kind of perennial herbaceous flowering plant and most varieties are highly dependent on ramet propagation. Some varieties, such as Paeonia × ‘Coral Charm’, have characteristics relatively easy root cutting However, underlying adventitious buds cutting, the molecular mechanisms still not completely understood. Here, we collected four key stages bud formation P. Charm’ for transcriptome sequencing, assembled annotated 326,139 transcripts. By carrying out weighted gene co-expression network analysis, three functional modules several biological metabolic pathways related to were identified. Finally, determined six transcription factors in MYB, HD-ZIP, C2H2 bZIP family that may play role formation. These results provided insights into peony, laid theoretical foundation rapid propagation Paeonia.
