The lookout leaves of street trees, you want to create a lighting power is not needed.

Research team of Nagai Professor of Osaka has developed three types of proteins that shiny blue-green and yellow-green, to orange. Can be the mark of a particular gene and cell, applications such as Moto-ya iPS cell research is expected.
The same study the fluorescence proteins are widely used, need to apply ultraviolet, effects on cells were problems. The team improved the protein of shiny himself in the sea coral, was achieved brightness that can be seen with the naked eye.
In this three types, plant shining in various colors that can be achieved. Nagai professor says the dream to be "keeping an leaves of trees, want to make the lighting power is not needed." It seems can expect a variety of applications.



大阪大の永井教授の研究チームが、青緑や黄緑、オレンジに光る３種類のたんぱく質を開発した。特定の遺伝子や細胞の目印にでき、がんやｉＰＳ細胞研究などへの応用が期待される。
　同様の研究には蛍光たんぱく質が広く使われるが、紫外線を当てる必要があり、細胞への影響が課題だった。チームは海中で自ら光るサンゴのたんぱく質を改良、肉眼でも分かる明るさを実現した。
　この３種類で、さまざまな色に光る植物も実現可能という。永井教授は「街路樹の葉を光らせ、電力がいらない照明灯を作りたい」と夢を語る。様々な応用が期待できそうですね。
