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?
