By inserting bacteria into the petals of a white rose, a group of scientists claim to have created the first engineered blue rose.
Gardeners have attempted to create blue roses for ages without success. The ability to breed blue roses in gardens may soon be possible thanks to contemporary biotechnology.
What made the breeding possible?
By expressing bacteria-produced pigment-producing enzymes in the white rose’s petals, researchers were able to tint the blossoms blue.
L-glutamine, a typical component of rose petals, may be converted into the blue pigment indigoidine by two bacterial enzymes, according to a study that was published in the journal “American Chemical Society, Synthetic Biology.”
Do blue roses naturally exist in nature?
No, blue roses don’t exist in nature, but florists can make them by dipping cut roses in dye to create blue-hued blossoms.
Researchers from the Suntory Global Innovation Center in Japan had previously created a blue rose in 2004 through a combination of genetic engineering and selective breeding after a laborious 20-year endeavor.
Chinese Academy of Sciences and Tianjin University researchers sought to create a straightforward method for growing a true-blue rose.
The scientists created an Agrobacterium tumefaciens strain with two pigment-producing genes from separate bacterial species in order to do this.
Where are blue roses grown?
For the longest time, people yearned for blue roses, but it seemed impossible. Fortunately, we already have blue flowers thanks to updated technical breakthroughs.
White roses are crossed with other flowers that have blue pigments, which roses do not, to create blue roses. White roses are given a blue tint by having the pigments injected into them. After that, the flowers are stored to keep their beauty and freshness.
White roses can also be dyed blue to produce blue roses. Cut rose flowers are submerged on the mixture by their stems after mixing blue dye and water. The white petals will eventually turn blue after a few hours as the blue color spreads throughout them.
Using spray paint to create blue roses is also a successful technique. To create a consistent tone, the technique calls for evenly spraying a flower spray paint onto white petals. To make the petals darker, a second coat of paint is applied after drying.
Exists a rose that is naturally blue?
Blue roses have been bred by gardeners unsuccessfully for ages. But now, thanks to contemporary biotechnology, it might be possible to finally obtain the elusive blue rose. In order to give white rose blooms a blue hue, scientists have discovered a way to express enzymes from bacteria that produce colour in the petals.

Blue roses have been bred by gardeners unsuccessfully for ages. But now, thanks to contemporary biotechnology, it might be possible to finally obtain the elusive blue rose. In order to give white rose blooms a blue hue, scientists have discovered a way to express enzymes from bacteria that produce colour in the petals. In ACS Synthetic Biology, they publish their findings.
Despite the fact that blue roses don’t exist in nature, florists may make them by dipping cut roses in dye. Additionally, over the course of a laborious 20-year project, biotechnologists used a combination of genetic engineering and selective breeding to create a “blue rose.” The rose, however, is more mauve than blue in hue. Yan Zhang, Yihua Chen, and other team members sought to create a straightforward procedure that could generate a true-blue rose.
The two bacterial enzymes that together can transform L-glutamine, a common component of rose petals, into the blue pigment indigoidine were chosen by the researchers for this purpose. The researchers created an Agrobacterium tumefaciens strain with two pigment-producing genes from a separate bacterial species. Because A. tumefaciens easily inserts foreign DNA into plant genomes, it is frequently utilized in plant biotechnology. The bacteria transferred pigment-producing genes to the rose genome when the scientists injected the modified bacterium into a white rose petal, and blue color spread from the injection point. The team claims that the rose grown in this study is the first manufactured blue rose in the world, despite the color’s fleeting and patchy nature. According to them, the next stage is to genetically modify roses so they can naturally create the two enzymes without the need for injections.

Where can you find blue roses in nature?
A blue rose is a flower from the genus Rosa (family Rosaceae) that has blue-to-violet coloring rather than the more typical red, white, or yellow coloration. The color blue is frequently used to denote mystery or achieving the impossible. [1] However, they don’t occur in nature due to genetic restrictions. In 2004, scientists employed genetic engineering to produce roses that possess the delphinidin blue pigment.
Conventional hybridization techniques have been used to create so-called “blue roses,” however the end products, like “Blue Moon,” are more appropriately described as lilac in hue.
Stories of development>
Since no one could ever successfully develop blue roses through hybridization, the term “blue rose” in English came to mean “the impossible (a non-existent thing)” despite how much people wanted them. But because to cutting-edge biotechnologies and the persistent work of scientists committed to growing blue roses, “the impossible” has now become a reality. Principal Researcher Yukihisa Katsumoto, Ph.D., who is still actively involved in the study as the project leader, Senior General Manager Yoshikazu Tanaka, Ph.D., Researcher Noriko Nakamura, Ph.D., and Senior General Manager Yoshikazu Tanaka, Ph.D. discussed their passion and aspirations that contributed to the development of blue roses.
To generate blue roses, two technical challenges have to be overcome. Among the tens of thousands of genes found in blue flowers, one was to “isolate genes (blue genes) necessary to synthesis a blue pigment (delphinidin).” The second was to “create the techniques for introducing these genes to rose cells and producing genetically modified roses from these cells.” Since blue genes might be patented, it was especially important to address the first problem of isolating them before competitors and submit an application for the gene’s patent.
The task of creating “blue roses,” which stand for the impossibility, began. Yoshikazu Tanaka, Ph.D., Senior General Manager
Although there are numerous plants that naturally produce blue blooms, our research team initially chose a petunia that has a dark violet hue in order to separate blue genes. This was because the petunia had already acted as a model plant for the studies of flower pigments (such as anthocyanin) and their production and the following knowledge had already accumulated:
– Blue genes are cytochrome P450 type hydroxylases, which are liver detoxifying enzymes.
To find the two blue petunia genes, we chose 300 potential gene types among the 30,000 or so petunia gene types that exist. Our initial strategy was to test if the suggested genes were in fact blue genes by introducing them into petunias and observing changes in bloom color. To see a color change using this method, flowers had to bloom first and take several months to do so. We therefore chose to transfer the candidate genes of blue genes to yeast instead of plants and assess their enzymatic activities in yeast in order to shorten the time needed to achieve results. With the use of this technique, we were able to evaluate the activity of several genes and receive results in just one week.
The happiest period in my research career was when we identified blue genes. Yoshikazu Tanaka, Ph.D., Senior General Manager
1994 Petunia blue genes were added to roses, and the flowers opened up, but the roses lacked any blue tint.
Genes can be inserted into plants using a variety of techniques. We used an approach to introduce them in the Blue Rose Project that involved the use of the “Agrobacterium” soil bacterium. This bacterium is utilized in the gene transfer of many plants because it has the capacity to convey its own genes into plant cells. It is vital to optimize plant hormones as well as types and quantities of nutrients in order to choose only cells that have received the genes after transfer and regenerate them into the plant body of roses. “Tissue culture” refers to the effort done to carry out this method with a plant in a test tube under sterile conditions.
In the case of roses, the time between the introduction of genes and blooming is roughly one year. We need to create as many genetically modified roses as we can because how well the added genes function varies from one genetically modified rose to another. By rose variety, there are also significant differences in gene introduction efficiency. Consequently, we kept performing tissue cultures while learning from our mistakes.
We were finally successful in introducing genes to red roses. In 1994, roses with two different blue petunia gene varieties were initially opened. Despite the introduction of the genes without a doubt, the flowers’ color remained red and no blue pigment was found.
Even after using numerous promoters (DNA sequence regulatory gene expression) to drive the petunia blue genes, color changes or delphinidin were not noticed. As a result, we decided to breed blue genes into roses from sources other than petunias. In order to breed blue roses, we isolated blue genes from a variety of blue flowering plants, including gentian, butterfly pea, and torenia. We tried numerous times, but only “roses with blue genes but without blue pigments” blossomed.
We even thought that blue pigments in roses would break down. Yoshikazu Tanaka, Ph.D., Senior General Manager
Although we encountered several setbacks, each one served as a valuable lesson for the future Principal Researcher Yukihisa Katsumoto Ph.D.
We were unable to reap the rewards of our labor, and the participants in this enterprise continued to experience hardship. The achievement of the creation of blue carnations that had undergone genetic modification gave the researchers hope. Petunia blue genes performed as expected in carnations but poorly in roses. The blue “delphinidin” pigments accumulated, changing the color of flowers from pink to blue.
In 1997, these flowers, known as “Moonseries,” were first sold in Japan, and since then, the variety has grown. Popularity has grown for these graceful and lovely blooms, which in the language of flowers denote “everlasting bliss.”
The first commercially available genetically altered flowers are called Moonseries. Currently, these blue carnations are grown in Ecuador and Columbia and sold largely in the USA, however they are also available in several other nations and in Europe. Six types with various dark and light color combinations are offered for sale in Japan. Currently, some types use pansy blue genes in addition to petunia blue genes.
According to senior general manager and Ph.D. Yoshikazu Tanaka, “blue carnations” were created employing a gene in addition to the blue gene.
Is a blue rose uncommon?
One of the most popular flowers to send to a special someone or a loved one is a rose. The blue rose is becoming more popular to send because it is uncommon and exceptional and shows how special the receiver is to the giver. The rare blue rose, the ideal valentine’s gift, represents devotion, trust, and love. The Blue Rose is the most uncommon color of rose, therefore you can anticipate that the cost of the flower will be higher than other hues. When ordering a bouquet of these enigmatic flowers, it is best to get in touch with your florist well in advance because the blue rose is a distinctive rare color.
Black Rose: Is It Real?
Black roses don’t exist in nature, but plant breeders have been able to make some varieties’ colors darker. Rosa ‘Almost Black’ is the flower in this illustration. As you can see, the cultivar name is illogical as the hue is simply dark red. By dipping the stems of flowers in colored water, florists can change the appearance of the flowers to match the occasion (consider green carnations for St. Patrick’s Day).
So what do black roses symbolize in the language of flowers? Black roses can have a variety of meanings. Additionally, if you intend to send someone a symbolic message, be sure to include additional cues to prevent message misunderstanding.
We list a handful of the potential meanings of “black roses” below. They may represent:
- Death (actual)
- Death (metaphorical: for example, the end of something; a significant life change)
- Revenge
- Resistance
- grief, despair
- Mystery
- Evil (as in the dark side of our psyches)
Other motives for purchasing or sending black roses include:
- The hue is bold, cool, and minimalistically attractive.
- They appreciate Gothic aesthetics and other comparable subcultures and lifestyles.
If you want to know the meaning of receiving or gifting black flowers, you must take the recipient and the situation into account. There are so many possible outcomes. Therefore, if someone sends you black roses—someone you know to adore that hue because it’s trendy or eye-catching—it could not be out of malice, retaliation, or the desire to end a relationship.
Real or fake purple roses?
In the truest sense, there is no such thing as a purple rose. The hues of lilac, blue, plum, and lavender are included in the group of purple roses. Typically, pastel shades are used. In the only 1800s, the purple rose first appeared. The purple rose was a cross between the common European rose and the rose variety brought over from China.
Do Purple Roses Grow Naturally?
Not quite. Purple roses are produced by crossing various rose varieties, most frequently white and pink and occasionally red. They can be grown organically, and they do occur in the wild. Lavender, deep purple, and burgundy are just a few of the unusual tints and colors that can be produced by cross-hybridization or breeding. Europeans, and notably the Dutch, were the first to breed purple roses.
Where can one find Black Rose?
Turkey’s black rose will be made known to the globe through the Rose Union that will be created by Cittaslow, an Italian movement that aims to slow down the speed of life in cities and promote ecological harmony.
The black rose, which is unique to Turkey and only found in the Halfeti region of the province of Anlurfa, is well known for its petals, which turn completely black in the months of March through April and October through November. Other seasons bring about a slight shift in its color.
The Halfeti District Council Chair Nihat Zdal debunked other similarly dark-petaled roses that were brought from the Netherlands and outlined how the flower’s black color is due to the environment and terroir of the region. The only place where the original black roses grow is in Halfeti; there has been no genetic tampering here, according to zdal. “Those cultivated in the Netherlands or in other countries are roses that have had their DNA altered and grown in greenhouses.”
