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.
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.
