Orchid NAC Transcription Factors: A Focused Analysis of Genes
Overview
Affiliations
Plant transcription factors are involved in different developmental pathways. NAC transcription factors (No Apical Meristem, Activating Factor, Cup-shaped Cotyledon) act in various processes, e.g., plant organ formation, response to stress, and defense mechanisms. In the NAC transcription factor CUPULIFORMIS (CUP) plays a role in determining organ boundaries and lip formation, and the CUP homologs of and are involved in flower organ formation. Orchidaceae is one of the most species-rich families of angiosperms, known for its extraordinary diversification of flower morphology. We conducted a transcriptome and genome-wide analysis of orchid s, focusing on the No Apical Meristem (NAM) subfamily and genes. To check whether the homologs could be involved in the perianth formation of orchids, we performed an expression analysis on the flower organs of the orchid at different developmental stages. The expression patterns of the genes of suggest their possible role in flower development and symmetry establishment. In addition, as observed in other species, the orchid and genes seem to be regulated by the microRNA, miR164. Our results represent a preliminary study of NAC transcription factors in orchids to understand the role of these genes during orchid flower formation.
