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.

Bioengeered? That's a resounding yes.

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.
