Can All Plants Be Preserved in Seed Banks?
Today's episode is brought to you by Oregon. You know, when something goes wrong at home, and you just freak out. I have definitely had my moments, especially when it comes to pests ants in the mirror, Nara, cockroaches, hanging out around your bubble, bath and uninvited rat a your daughter's birthday party.

If you've ever heard of a seed Bank, the basic idea is this when the apocalypse is over and the forests are nothing, but smoking ruins and the fields Barron of grain fear. Not we can rebut the world thanks to our bench seeds stored in bunkers strategically located from here to eternity. These fall barred international seed vault in Norway, for instance, currently holds more than eight hundred eighty thousand seeds and has the capacity to hold up to two point five billion. Seeds are pretty amazing forms of reproduction. All you need to do is dry them out and freeze them solid and they can last for years. It's a comforting thought and ace up civilization sleeve, and the seemingly less and less unlikely scenario that we self destruct the UN's global strategy for plant conservation plans to Bank seventy five percent of all plant species by twenty twenty but hold that. Arguably comforting thought according to a study from researchers at the Royal Botanic Gardens Q, there's a significant catch they discovered that whole host of plant seeds just can't be banked, including Cotto ca cow and mango their findings which were published in November twenty eighteen issue of the journal nature plants detail, how a full thirty three percent of tree species alone are on this list, including oak and chestnut. Trees were still thirty six percent of our critically endangered species are also on bankable, and that's not even counting twenty seven percents of the regular old endangered plants or thirty five percent of the vulnerable ones. So why can't these seeds be banked apparently, not Alcides like the drying out process and for this? They're labeled recalcitrant seeds, which seems a little unfair calling. Seed stubborn just because it can't tolerate dehydration as a bit rich coming from species that can barely last two days without water. Luckily, there's a way out of this jam and it involves liquid nitrogen, which is always fun. Yes. To make sure we've got all our seeds safely tucked away in indefinite storage. We have to resort to cryopreservation dislike Ted Williams and all the other immortals being kept on ice. All one has to do is dissect the seed, priorites embryo and plunged into smoking cold nitrogen instead of storing seeds at conventional negative twenty degrees celsius that's negative for degrees Fahrenheit, going cry. Oh will keep these finicky seeds in suspended animation at a subglacial temperature of negative one hundred ninety six degrees celsius that's negative three hundred and twenty degrees Fahrenheit. Some researchers advocate cryopreservation for all seeds, even the cooperative ones because they'll last longer. Of course, a full out. Apocalypse isn't the only reason for banking seeds climate change habitat loss and the growing threat of plant pathogens are already threatening bio-diversity. So the time to preserve seeds is now though taking steps to protect habitats and slow climate change would certainly be good as well.
