Glow-in-the-dark Christmas Trees

lawrence writes "The BBC is carrying this story about five post-grad students at the University of Hertfordshire who are planning on creating a glow-in-the-dark christmas tree. They would do this by adding the genes that cause glowing in fireflies and jellyfish, making the pine-needles glow all the time. They expect the cost of the trees to be about £200 ($330) Future possibilities involve coral genes that would make it multicolored. " I think my favorite part about this story is the comment about Americans being a likely market. *grin*

    It's not quite as far out as you'd think, but there are many challenges ahead. Firefly luciferase has been expressed in tobacco plants, which bioluminesce when provided with luciferase to the roots. I haven't seen this done beyond small seedlings, though, and there are many concerns. There are huge energy costs to the plants, and they may be toxic side effects from the unexpected proteins.

    GFP has also been used to create transgenic plants (and animals!) There are mice, for instance, that produce GFP in every cell in their body. This doesn't require as much energy as GFP is merely fluorescent (and this the fluorophore needs to be excited by external UV light), but this also makes it less attractive for the coolness factor.

    If you're interested in this further, I highly recommend the book "Green Fluorescent Protein : Properties, Applications, and Protocols" by Martin Chalfie and Steven Kain (eds.). I've been reading through it quite a bit in lab, and it's a wonderful resource.

    Since I know a little bit about the subject, this article strikes me as both an obvious idea and a peculiar (impossible) approach to implementing it.

    Luciferase is a firefly gene that catalyzes the breakdown of the chemical luciferin, emitting light in the process. (Yellow light.) Fireflies "blink" by controlling the access of luciferase to luciferin. A plant isn't going to blink since it doesn't have the appropriate control machinery (e.g. no neurons to send a signal saying "turn on now"). But a plant could always simply glow steadily. Unfortunately, plants don't make luciferin, and normal luciferase doesn't catalyze anything in a normal non-firefly-light-organ cell. I presume that the postdocs have figured out a way to get around this.

    Even stranger is the idea to use GFP. GFP (green fluorescent protein) is responsible for most of the neat pictures of glowing organisms that you're likely to see. However, what they don't tell you is that since it is fluorescent it requires violet or blue light as input. GFP absorbs violet or blue light, blah blah Stokes Shift blah blah, and emits green light. If you're going to shine blue light on your tree, why bother with all the confusing luciferase stuff and--if you want yellow--just include YFP as well (which works just like GFP except it emits yellow, or actually more chartreuse, light).

    My guess as to what the group is really trying to do is this: find and use a luciferase-like gene that creates bioluminescence out of common cellular energy carriers, e.g. NADPH. Plants store the energy from sunlight in NADPH, so if you express this gene, they'd glow (at least during the day...). Furthermore, the reaction would ideally produce blue light. It's tough to get blue light out of a plant, because cholorphyll absorbs blue light. But if you tack on a GFP, it will convert the blue light to green and you'll be able to see it fine. Likewise for yellow with YFP. If you want orange or red, you can tack on both a GFP and a coral fluorescent protein, which will turn green light into an orangy color.

    It makes a nice headline, but it sounds rather complicated to me. I wouldn't hold your breath for these trees.

GFP's excitation spectrum peaks at about 450nm (blue) depending on which variant you use. The luciferin emission spectrum is broad, but if it looks yellow anyway (what color are fireflies?), why change it? (Note that removing the blue component and turning it green would make the glow look even more yellow than before...maybe it's just because they can't stand to waste any of the blue photons since their fertilizer is so expensive?

A ribosome runs down the chain of DNA (well, I'm skipping some stuff, but...) that's been invoked and reads each word, chaining together the amino acids into a protein. To have a cell make a specific protein, all you have to do is insert the correct 'words' into the DNA strand. It's a lot like adding a printf statement to code that's already there...it's pretty easy to do without breaking stuff. So making a plant or a fungus or whatever make luciferase is relatively easy, because luciferase is a protein. Luciferin, however, is not a protein, so you first have to make the apparatus to make the chemical out of other proteins. So there are any number of steps in between transcribing several different genes to make several different proteins to make the stuff...perhaps just one, perhaps many. So basically, luciferase is very portable. Your compiler can handle it whether it's running on an animal or a vegetable or whatever. But Luciferin is like doing video. You need the right hardware, or at least the right libraries, because the code that'll draw a circle on a Win98 machine might have trouble on a mac or a linux machine or even under dos.
