The birth of the first blue chrysanthemum in the world

The birth of the first blue chrysanthemum in the world we all know that the most common varieties of chrysanthemum are yellow or pink, but have you seen blue chrysanthemum? Recently, Japanese scientists have successfully planted the world's first blue flower through DNA cultivation.

According to the daily mail of July 26, Japanese scientists have finally cultivated the world's first true 'Blue' chrysanthemum after years of dedicated research. This chrysanthemum is cultivated by extracting DNA from three kinds of plants, which is a breakthrough in the scientific community and is likely to make a new look to the garden.

In life, many people think that they have seen blue flowers, such as hyacinth, but actually the color of these flowers is purple or blue purple, not the real blue. The chrysanthemum has been recognized by the Royal Horticultural Association as the world's first 'true' blue flower.

In order to produce blue chrysanthemum, scientists first extracted the DNA of butterpea and Campanula, implanted it into the same E.Coli, and then infected the mother chrysanthemum with the transgenic E.coli, thus transforming the gene of blue flower into the mother chrysanthemum. After that, we will plant the seeds of chrysanthemum after transgenic transplantation, and after another year's cultivation, we can grow blue flowers. Because the DNA of blue flowers only exists in some genes of E. (this article is edited and collated by, reprinted and noted with source, original link:

The research process and results were published in the authoritative scientific journal "scientific progress" by the Comprehensive Research Institute of agricultural and food industry technology of Japan. The first author of the paper pointed out that the cultivation of blue chrysanthemum requires three different plants: Butterbean, Campanula and chrysanthemum, which is very difficult and time-consuming. It is reported that after many failures, the team took 13 years to cultivate the real blue chrysanthemum.

Scientists say that flowers with blue or purple genes are very rare, and only a few species can be extracted, such as Campanula, cornflower, delphinium, haidongqing and Himalayan blue poppy. According to the unofficial survey, blue is one of the most popular flower colors, second only to pink, so the market potential is huge.

Scientists also pointed out that transgene can not be passed on to the next generation through seed propagation, but can be propagated asexually through cutting and tissue culture. David baulkum, a professor of Botany at Cambridge University, said: 'people have been trying to cultivate blue roses and blue chrysanthemums for many years. Although I don't like blue very much, this blue chrysanthemum is indeed a successful case of transgenic culture. '
