Every cell has its division limit. But plants cell looks like don't have it (like Sequoia sempervivens D.). I searched a little for it but what I have found didn't help to answer my question. I found a paper http://epsce.com/wp-content/uploads/2016/02/EMBRYONIC-PLANT-EXTRACTS-EXTEND-THE-HAYFLICK-LIMIT.pdf, which states that plants cell have something call EPE. Which seems to me like super telomerase ( Just kidding don't take it seriously).

My question is: How do plants slow their aging process? Have they different limits for cell division? Are phytohormones related to this phenomena?

    $\begingroup$ Sequoias are perhaps not the best example. Consider clonal organisms like the quaking aspen (Populus tremuloides), one grove of which is estimated to be about 80,000 years old (and some suggest much older): en.wikipedia.org/wiki/Pando_(tree) $\endgroup$
