The secret of the rose 's gene finally revealed that "closer to strawberries" than I thought

byLaura Ockel

Roses have various colors and scents depending on variety, but the rose genes are very complex, and it has long been unknown which genes have determined the scent and color of roses. Therefore, surveys were conducted by more than 40 scientists in France, Germany, China and the UK, and for the first time rose genetic information was revealed. Roughness seems to be closer to "Ichigo" than it was thought so far.

Roses are useful as decorative and perfume materials, and they exist as one of cultural and economically important flowers. It is said that roses for decorations have been grown from ancient Greece, but rose genes are not so complicated, and researchers have succeeded in "genome assembly" which restores the target genome sequence by connecting pieces of fragment information of DNA It was not. The reason is that analysis result of rose genome is fragmentary and it was difficult to decipher as a whole.

In such a situation,Lyon Higher Normal SchoolThe research team led by Mr. Mohamed BendermannRosa KinensisWe succeeded in elucidating the genome sequence of the breed of high precision. Rosa Kinensis is a rose which originated from China, which is the origin of various modern roses and is also called "Old Brush". Researchers have successfully decoded genetic information on seven pairs of chromosomes and successfully characterized all of the 36,377 genes.

"Thanks to the high-quality genome assembly, we were able to know the information the gene coordinates, such as the biosynthesis of the scent of roses, the resistance to color, flourish, biological and inanimate stresses," Mr. Benderman I am telling you.

In addition, researchers compared the genes of strawberry, apricot, peach, apple, and none to explore the evolution of rose and the original species, and found that three of rose and strawberry and raspberry are very closely evolved It turned out. It turned out that roses and strawberries are closer species than we thought so far.

Research has revealed the biosynthetic pathways and main genes of plants and floral development, breeding, fragrance and pigment synthesis, and the research team has succeeded in restoring the biosynthetic pathway that these genes intervene . In particular, the research team emphasizes the existence of a group of genes that simultaneously regulate the scent and color of roses.

The genetic information of roses revealed in this survey is considered to be useful for developing varieties with specific characteristics such as "varieties keeping beauty long in vases" and "varieties resistant to pests" It is done.
