Transposé Genes to light up flowers (livescience.com)
Red roses and lumineux, pétales poinsettias flames for Christmas and shrubbery which allume communities in the middle of the night, rendu street lights unnecessary-this the vision behind the company, BioGlow, Inc.
The vision was an important step in toward reality when one fondateurs, Alexander Krichevsky, and other researchers in transplanter genes in tobacco companies allowing marine bacteria to light up. Kisses two companies lumineux]
This is the first time, companies had to give light on their own, according to Krichevsky, is a teacher assistant Engineering génétique in New York State University in Stony Brook.
"All that company précédemment lumineux, '' genetically usinés you, had to be done either aspergés and chemicals or rétroéclairé and external source light to produce a temporary effect lumineux, '' the LiveScience Krichevsky in an e-mail.
In the same way as to a light sheet is no longer all fondateurs de BioGlow want it.
'' We have five minutes in the dark have seen them with your eyes, '' Krichevsky said, referring to the period of human eyes to needed adjustment in the darkness, '' We even if we're going to make them like lumineux as fireflies. ''
There are about 30 different systems being used by living things, bacteria, insects and dinoflagellates, champignons, to produce its own light, according to Krichevsky and his colleagues, published the results in the journal Science HONORS PLoS 12 November. They nurse on lighting system being used by marine bacteria.
Krichevsky and his life-blood, about six bacterial genes, what code to enzyme luciferase, who catalyzes a light émettant chemical reaction and other ingrédients necessary to the chemical reaction in genetic material inside have pigment plant structure named plastids.
Marine Bacteria lumineux, free-living especes who served as decomposers on organismes dead, like symbiotes gives light to the fish and squid they habitent. Insertion bacterial genes make most sense, because in their eyes you see green in a facility ancestor bacteria, according to Krichevsky.
Company leaves appear green because they are chlorophyll pigment in structure, whose name was. In the past you were free-living bacteria that eventually became partners, or symbiotes, and other red blood cells leading to two companies.
The color is determined by the glare luciferase, could be modified to emit multicolor, so, for example, pétales flowers could light red, according to Krichevsky.
When asked if memory of lumineux companies can take images of nuclear contamination to ignore, for a few, Krichevsky said already troubled to hear this reaction of people in the floriculture community the general public.
"The only reaction I saw, '' my loved ones, I can find lumineux roses for Valentine day, '' he said.
For plastids organelles, who hold the pigments, maternally inherited, that is to say, they rule, future generations of ovule of a seed-there is no risk that they would passing genes in the environment by pollen, '' he said.
Although this project will add potential for sheds new light industry floriculture, lumineux flowers can't show in Windows English fleuristes too early, they said, Galvanized Eidelberg cofondateur BioGlow, Inc.
'' This is more of something visionnaire, '' he said.
