The rose ancestor has been yellow! – Iranian and world news

quoted PhysIn fact, all colored roses, including white, red, pink and peaches, are related to the “rose”. Genus Rosa is a subsidiary of the rose family. It contains a variety of flowers, including red, white, pink and yellow flowers.

Revitalization of ancestral characteristics through analysis Genomic The roses ended in a common ancestor, with a flower with 2 yellow petals. These findings in the journal Nature Plants Published.

Roses, which make up about 2 % of the flower market, are widely sold as ornamental plants and successfully Cooled Local grow. Everything began with the Renaissance of the Rose Breeding in the 1980s, which was characterized by the confluence of Chinese wild roses and European farming species or plants selectively cultivated by human intervention to create desirable characteristics.

Currently, there are more than 2 to 5 roses and more than 5,000 species, which represent a wide range of flowers with different colors and odors. However, climate change has made gold breeders focus on aesthetic features to variables that are easier to take and care for against factors such as drought and illness.

Borrowing genetic resources of different species of wild roses that have valuable features such as perfume and disease resistant is a promising strategy for cultivating a variety of roses and with little need for maintenance. A clear understanding of the root and evolution of the Genus Rosa, whether wild or cultivated, not only expands efforts to grow flowers, but also helps maintain and maintain extinct species of this flower.

In this regard, the researchers selected 3 samples of more than 5 types of roses, of which 5 % are recorded in Chinese plants. Samples after collection using sequence GenomicGenetic population and other methods were analyzed to determine their ancestral characteristics.

The researchers examined the single -copy gene as a set of preserved genetic markers that helped them classify evolutionary and geographical features and communication between rose species.

The ancestral features showed that the ancestor of all the samples examined is a yellow flower with a row of petals. With the evolution of the roses and their localization, new colors, distinct flowering features, and the ability to bloom in the category.
