Transcriptome Analysis Reveals Putative Target Genes of APETALA3-3 During Early Floral Development in Nigella damascena L.

ABSTRACT: Even though petals are homoplastic structures, their identity consistently involves genes of the APETALA3 (AP3) lineage. However, the extent to which the networks downstream of AP3 are conserved in species with petals of different evolutionary origins is unknown. In Ranunculaceae, the specificity of the AP3-III lineage offers a great opportunity to identify the petal gene regulatory network in a comparative framework. Using a transcriptomic approach, we investigated putative target genes of the AP3-III ortholog NdAP3-3 in Nigella damascena at early developmental stages when petal identity is determined, and we compared our data with that from selected eudicot species. We generated a de novo reference transcriptome to carry out a differential gene expression analysis between t
