In the eyes of Chinese people, chrysanthemum is a kind of plant that many literati like very much. It's usually yellow, but have you ever seen the blue chrysanthemum? Although scientists have spent many years studying it, Xiaobian always thinks the color is strange!
According to foreign media reports, after years of intensive research, Japanese scientists have finally cultivated the world's first true 'Blue' chrysanthemum. 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 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 exclusively compiled by WYH, editor of sihai.com. If you need to reprint it, please indicate the source and source. Related article link: http://www.4hw.com.cn/life/zone.html)
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 cultivation. '
