Consumers in the United States can now pre-order a genetically engineered plant for their home or garden that glows continuously. At a base cost of US$29.00, residents of the 48 contiguous states can get a petunia (Petunia hybrida) with flowers that look white during the day; but, in the dark, the plant glows a faint green. Biotechnology firm Light Bio in Sun Valley, Idaho, will begin shipping a batch of 50,000 firefly petunias in April.

Engineered petunia emits a continuous green glow thanks to genes from a light-up mushroom.

Was going to order one because it's only $29 but damn, the shipping was $24.

[-] SteveKLord@slrpnk.net 3 points 1 year ago

That's gotta be around 95% shipping! I'm still a bit tempted and can almost justify it if I consider it as insurance to make sure such a rare plant arrives safely. It's definitely misleading marketing to say it's $29, though.

This is wild. It's an annual but sometimes you can keep them alive longer. I wonder if they programmed a kill switch in so you can't do vegetative propogation or sterilized it so you can't produce seeds.

[-] Sunforged@lemmy.ml 9 points 1 year ago

Bioengeered? That's a resounding yes.

[-] Sludgehammer@lemmy.world 4 points 1 year ago

There's never been a commercially available plant variety that's been genetically engineered to be sterile.

[-] SteveKLord@slrpnk.net 9 points 1 year ago

Hmmm... that's an interesting concern. The article says the company doesn't plan to crack down on those who might share with friends so it seems like they expect it to happen. I imagine it's only a matter of time before someone someone is able to get seeds from the plant. Just imagine what could happen if they ended up in seedbombs.

I wonder if they programmed a kill switch in so you can’t do vegetative propogation or sterilized it so you can’t produce seeds.

Probably not, stopping vegetative propagation would require mucking around with root genes so it'd be a huge mess to keep the roots working correctly. As for sexual reproduction, despite all the fearmongering about "the terminator gene" there's never been a commercially available plant genetically engineered sterile. In fact the technology never made it out of the early testing/seeing if it actually worked phase.

They could however make the plant sterile through non-genetic engineering methods, like breeding a triploid. But that'd be kinda pointless since you could still just make cuttings.

I'll be able to locate my cat's barf easier.

The benefits are endless! The future is indeed bright.

[-] CounselingTechie@slrpnk.net 10 points 1 year ago

I will be honest, I partially want to wait to see how it goes for others first, and then make my own purchase to see how it works for me.

[-] SteveKLord@slrpnk.net 2 points 1 year ago

That's understandable. It's always risky to be an early adopter. I really hope the majority of these survive and thrive 🤞

[-] CounselingTechie@slrpnk.net 3 points 1 year ago

Agreed! That being said I am being peer pressured by my friend group to get it, since I am already known for being the plant person, lol.

[-] SteveKLord@slrpnk.net 3 points 1 year ago

I suppose plant peer pressure is the least threatening type lol. Your friends should pitch in for shipping if they want to see those glowing baddies so badly.

[-] jadero@slrpnk.net 10 points 1 year ago

My wife is nuts for glow in the dark stuff. Too bad we live in Canada.

[-] SteveKLord@slrpnk.net 6 points 1 year ago

You could try reaching out to the company and asking if they're able to ship but my guess is it would have to be approved by customs in Canada.

[-] jadero@slrpnk.net 9 points 1 year ago

Oh yeah, I don't think moving plants across the border is for the faint of heart or shallowness of pocket.

[-] Radium@sh.itjust.works 7 points 1 year ago

Cool! I bought my wife and I each one. I’ll probably try and propogate it into leca and grow it in my office year round under grow lights 🤞. The shipping hit hurts less for two plants

[-] SteveKLord@slrpnk.net 5 points 1 year ago

It'll be amazing to see how these look in different settings! The company points out in their FAQ that the plant does require several hours of direct sunlight daily as they harvest energy for the bioluminesence from the sun.

How were they? Did it blow your minds?

Figure 1. Features of the fungal bioluminescence system. a. Spectrum of fungal bioluminescence (Neonothopanus nambi, in green) overlaid onto the absorbance spectrum of plant leaves (Nicotiana tabacum, in dark gray). b. The caffeic acid cycle shares metabolites with some of the major plant biosynthetic pathways. The fungal or plant origin of enzymes is indicated with mushroom and plantlet symbols, respectively. Abbreviations: 4CL — 4-coumarate:CoA ligase; C3H — p-coumaric acid 3-hydroxylase; C4H — cinnamic acid 4-hydroxylase; CCOMT — caffeoyl-CoA 3-O-methyltransferase; CCR — cinnamoyl-CoA reductase; CHI — chalcone isomerase; CHS — chalcone synthase; CPH — putative caffeoyl pyruvate hydrolase; H3H — hispidin-3-hydroxylase; HispS — hispidin synthase; Luz — luciferase; PAL — phenylalanine ammonia-lyase. Absorbance spectrum of leave is representative of experiment performed on three leaves. Luminescence spectrum is rendered from dataset published in Ref.

Oh Luciferase, where have they put you now, my friend?

Lunarpunk is a subgenre of solarpunk with a darker aesthetic. It portrays the nightlife, spirituality, and more introspective side of solarpunk utopias. It can be defined as "Witchy Solarpunk." Aesthetically, lunarpunk usually is presented with pinks, purples, blues, black, and silver with an almost omnipresence of bioluminescent plants and especially mushrooms
