Scientists Clone Oldest Living Organism 141

goran72 sends along the story of the world's oldest living organism, a shrub that grows in Tasmania and reproduces only by cloning. Tasmanian scientists have cloned Lomatia tasmanica as part of a battle to save it from a deadly fungus. From the RTBG's press release (which seems to load slowly in the US):"The Royal Tasmanian Botanical Gardens [RTBG] is working towards securing the future of a rare and ancient Tasmanian native plant... Lomatia tasmanica, commonly known as King's Lomatia, is critically endangered with less than 500 plants growing in the wild in a tiny pocket of Tasmania's isolated south west. The RTBG has been propagating the plant from cuttings since 1994... 'Fossil leaves of the plant found in the south west were dated at 43,600 years old and given that the species is a clone, it is possibly the oldest living plant in the world,' [Botanist Natalie Tapson] said."

            There's nothing unnatural about it at all. Cloning is a not-uncommon way for plants to reproduce. A branch falls off, and instead of dying, it just becomes a new plant. It isn't cloning in the specific way that us metazoans are cloned, but the net effect is the same- a new individual that's genetically identical to the originator. That's how Lomatia tasmanica reproduces and has reproduced for a long time now. All we've done is help it along since 1994.

              Nono, every 20,000 years or so an advanced civilization rises up from the prairies and survives roughly long enough to clone the plant in a lab. The plant has naturally evolved a mechanism whereby it propagates a miles-wide fibrous network of false fossils to interest paleontologists, with the most interesting fossils around the plant itself.

              It's an extraordinarily patient tree.

                Part of the organism still lives at the very place the oldest fossil leaves are found, and there is no evidence of the whole organism ever dying there. So we can assume that the very organism that shed those leaves is the same that is still living (and cloning itself) today.

      This is arguing something different--- not that it's the earliest-to-emerge species with still-living individuals, but that this particular individual is the oldest one still alive. That depends on your definition of "organism" and "individual" and such. Clonal colonies are a bit of an edge case--- they reproduce by continuously producing what could be seen as new individuals, or could be seen as just new branches of the original individual (they often come up from the same root system). To take a similar example, is Pando [wikipedia.org] a single organism with a lot of trunks, which has been alive for tens of thousands of years; or is it a colony of individual trees, each of which has been around a lot less long?

      And you can find even more edge cases--- there are stable mats of seagrass that might be 100,000-year-old organisms, if you consider clonal colonies to be individual organisms.

      In other words, they have a specific plant which first sprouted nearly 50,000 years ago. If there's an individual horseshoe crab that is 50,000 years old I'd be very surprised.

    it is worth noting that in horticulture 'cloning' is simply the technical name for the process of propagating a plant through the use of cuttings.

    you need no lab to do it - just simply a pair of scissors (or a scalpel), some rooting gel/powder and a rooting medium (compost will do), and a healthy donor ('mother') plant to work from. using a propagation unit will also give better results (perhaps better still if it's heated). 'cloning' plants in this fashion is actually very easy to do - my mum's a keen gardener and she does it with all kinds of plants all the time (one poster here claims to have cloned a plant at age 6 - and i have no reason to doubt that at all!!).

    cloning is the primary method used to produce lots of (genetically) identical baby plants for use in commercial growing of all kinds (including, afaiu, in the illegal production of marijuana)

    personally, i don't think this is particularly newsworthy, even if they are doing this with one of the oldest plant species in the world.

    • This is an absolute untruth and is ignorant to an entire side of plant breeding which brings us some of our most important ornamental plants. Tissue culture is NOT sticking a tomato plant into a jar and waiting for it to sprout roots. Tissue culture is a heavily funded and researched science to clone plants which are not easily (or at all) able to be cloned. This process involves very sterile conditions and movement of plant tissue through various stages of nutrient and plant growth regulation in media.
