In photo Reuters recently, China's Yunnan team of scientists in the country for the first time the successful cultivation of the luminous plants, scientists bio-engineering technology, introducing a gene marine luminescent microorganisms to benthamiana plant cells, after a plant tissue culture and screening, The luminous plant has filled the gap in China's related technology and laid the foundation for further application of this technology in China.
The main leader of the project, Duan Kang of Yunnan Nabo Technology, said: "In the past, the luminescent plants cultivated by bioengineering must wear glasses under the illumination of blue-violet light to see fluorescence, or add fluorescein substrate to achieve short-term luminescence. The intensity is not visible to the naked eye and cannot be illuminated autonomously at night."
“Even when the phosphors are sprayed on the surface of ordinary plants for short-term luminous effects, these are not real luminous plants. The plants we cultivate are completely different. They can continue to emit light spontaneously in dark conditions, and the brightness can reach the level of starlight. It can illuminate a certain range.†It is understood that the world’s first luminescent plant was cultivated by Bioglow in the United States in 2014 and named “Starlight Avatarâ€.
"The key to gaining this ability is the marine luminescent bacteria. It is very difficult to obtain its complete luminescent gene. Another key is to successfully introduce the luminescent gene into the chloroplast genome of plant cells. There is only one nuclear genome in a plant cell. But there are hundreds of chloroplasts, and there are hundreds of sets of chloroplast genome copies in each chloroplast, which makes nearly 10,000 chloroplast genome copies per plant cell, so that plant luminescence becomes a possibility." Duan Kang further added .
R & D personnel are cultivating luminescent plants
It is understood that the introduction of luminescent genes such as firefly, macaque, deep sea squid and other genes into plants, allowing plants to autofluorescence, implementation is very difficult, and even some GM giants try hard to succeed.
Yan Hao, a special researcher at Guangxi Normal University, believes that the technology has a wide application prospect. He said that there have been many discussions on the use of luminescent plants for urban lighting, and some teams have made progress. “In the daytime, illuminating plants are no different in appearance from ordinary plants, only when the night falls. At least where glare is not required, illuminating plants are expected to replace some lighting facilities, reducing energy and equipment consumption. Can create a special night scene effect."
In fact, in 2015, Genome Compiler, a synthetic biology technology company in the United States, also developed the self-illuminating plant Glowing Plant. Their vision is to hope that the trees on the roadside will shine like street lights and become a new generation of environmental protection. Energy-saving lighting body.
In this regard, Duan Kang said that there is still a lot of work to be done. The next step of the team's work is to further improve the environmental brightness of the plant while assessing the brightness of the plant's luminescence. After the adoption, the technology is applied to ornamental plants such as flowers and flesh.
