Vivo red symbol of love, ancient pink or salmon pink up to the tones of orange and white: today The roses show off a rainbow of Corollebut not it has always been like this Why Once all the roses were yellow. It indicates thegenetic analysis Published in the magazine Nature Plants and conducted in China, in Beijing Forestry University.
There cultivation of roses began in XVIII centurywith the‘intersection Of Ancient Chinese wild roses And Ancient European varieties. Today have been obtained Between 150 and 200 species of roses, of which they exist More than 35,000 varieties of every color and perfume, which represent about 30% of sales of cut flowers. For this reason, the research, coordinated by Bixuan Cheng and Chao Yu, wanted identify genes that make the plant stress resistantlike those caused by diseases or climate change, in order to use them For get more robust species.
Any color have their petals, all roses belong to the pink genrewhich in turn is part of the Rosaceae family. But it was necessary to go beyond this knowledge and so the first step of the researchers was reconstruct the genetic sequence Of 205 samples of 80 species of Rosa. Once the genetic sequences were obtained, they were 707 genes identified And from these the analysis has yet gone back in timelooking for theirs origins. It was like this reconstructed in full the history ofevolution of rosesuntil they traced back to their common ancestor: it was a flower with a single yellow petal And Each leaf divided into seven leaflets.
