NtMYB12 requires for competition between flavonol and (pro)anthocyanin biosynthesis in Narcissus tazetta tepals.

The color of flowers is one of the main characteristics adopted for plants to attract pollinators to ensure the reproductive success of the plant, they are also important in their ornamental appeal in Narcissus plant. In this study, we identified a NtMYB12 locus encoding an R2R3-MYB transcription factor. Comparative transcriptome analysis of loss- and gain- of NtMYB12 tissue relative to wild-type narcissus showed NtMYB12 was mainly involved in flavonol and phenylpropanoid metabolic pathways.

Transcriptome-Based WGCNA Analysis Reveals Regulated Metabolite Fluxes between Floral Color and Scent in Flower.

A link between the scent and color of flowers can be anticipated due to their biochemical origin, as well as their similar biological role. Despite the obvious aesthetic and ecological significance of these colorful and fragrant components of the flowers and the molecular profiles of their pigments, fragrant formation has addressed in some cases. However, the regulatory mechanism of the correlation of fragrant components and color patterns is less clear.

Cryopreservation of orchid seeds through rapid and step freezing methods.

Ecuador has a great variety of climatic regions that potentiate biodiversity. The family constitutes one of the most important of the country, having identified about 4032 species with a high degree of endemism, therefore the development and research of alternative methods of storage and conservation of species is a strategy of primary interest for researchers and for society in general. In cryopreservation, temperatures reach below -190°C in order to paralyze the chemical reactions and keep the plant material viable for long periods.
