About this Research Topic
Over the past decades, significant progress has been made in several plant models towards understanding biosynthesis, degradation, transporter, transcriptional regulation of flower pigments during plant development or response to the environment. The relationship between pigment modification and flower coloration has been widely revealed though molecular and biochemistry approaches in petunia, chrysanthemum, rose, etc. In addition, varieties with new flower colors have been created with genetic manipulation. Blue-hued flowers of chrysanthemum, rose and carnation are generated via the introduction of heterologous genes to synthetize blue pigments. At present, genetic mechanism of flower color is still not clear in many ornamental plants. For example, more studies are needed to gain insights into feedback regulation in the pigment biosynthesis. This Research Topic is therefore focused on mechanisms underlying the development and regulation of pigment biosynthesis and flower color in ornamental plants.
We welcome submissions of original research and review papers. Manuscripts on the following subthemes are particularly encouraged but not limited to:
• Functional characterization of key genes involved in the metabolic pathway and transcriptional regulation of flower pigments
• Modification and transportation of pigments
• Regulation mechanism of environmental factors on flower pigment accumulation
• Metabolic engineering for flower color improvement
Keywords: flower color, flavonoids, carotenoids, ornamental plant, transcriptional regulation, secondary metabolites, metabolic engineering
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
