The trick is to use phytohormones to prime the seed [1]. It’s a relatively new technique that's plant specific so there aren’t any commercial products available to the general public AFAIK but we should see them hit the market in the next decade.

Does it? It's still interesting that they may have grown an ancient tree that has medicinal properties even if those medicinal properties aren't novel or useful.

Good luck waiting for that benefactor with the funds to pay for it, because it won't be the military pharmaceutical complex that doesn't make money if you're not coming back for more petrochemicals at dozens or more of dollars per gram.

Here's how I understand it, though I am just a layperson;

As all the strands of DNA in the cells of the seed degrade in different ways, the cells can still patch up the damaged DNA.

I assume 1/4th of the DNA can replicate enough after 1000 years.

Fruit trees can take a very long time to mature and grow flowers/fruit. Hopefully it can pollinate with itself, and isn’t a kind that has sexes.

Cloning is likely. Finding more seeds unlikely. The plant hasn't flowered or grown fruit yet so the story insult over yet...

It's an ancient variation of a tree species already still living in multiple counties. Probably not much to glean beyond that especially because it didn't flower or have any special attributes based on their tests over the 14yrs it's been growing

Arguably, it never went extinct. Theres a Turkish guy, Dr. Miski, who thinks he rediscovered an extant patch of it that may have been grown in an old anatolian village. DOI 10.3390/plants10010102

https://en.m.wikipedia.org/wiki/Silphium

that's actually what I went to the article to check on, if it was silphium. alas, it was not - had me excited for a moment.

but, resurrecting plants that are extinct is still very exciting.

Why is this getting downvoted?

Unfortunately, Silphium will likely never be resurrected. Even the Romans did not manage to grow it. Wiki:

Another theory is that when Roman provincial governors took over power from Greek colonists, they over-farmed silphium and rendered the soil unable to yield the type that was said to be of such medicinal value. Theophrastus wrote in Enquiry into Plants that the type of Ferula specifically referred to as "silphium" was odd in that it could not be cultivated.[16] He reports inconsistencies in the information he received about this, however.[17] This could suggest the plant is similarly sensitive to soil chemistry as huckleberries which, when grown from seed, are devoid of fruit.[2]

Similar to the soil theory, another theory holds that the plant was a hybrid, which often results in very desired traits in the first generation, but second-generation can yield very unpredictable outcomes. This could have resulted in plants without fruits, when planted from seeds, instead of asexually reproducing through their roots.[2]

PS: The poster (not me) seemed to have expected this. Throway...
