In plants, previous studies show that telomerase activity contributes to the maintenance of telomeric length for the proper development of organs and tissues. In this work, we investigated telomerase activity in during several years of cultivation. We found that during growth of the leaf there are two crucial phases: (1) the onset of cell elongation in 3 years and (2) differentiation of vascular bundles in 6 years. This coincides with the ages where the highest telomerase activity is seen. Therefore indicates that telomerase is associated with cellular activities such as; elongation, division, and cell differentiation. Likewise, we detected high activity during the period of vegetative growth, indicating that telomerase also contributes to telomeric maintenance on the leaf in .
在植物中，先前的研究表明，端粒酶活性有助于维持端粒长度，以促进器官和组织的正常发育。在这项工作中，我们在数年的培养过程中研究了[植物名称未给出]中的端粒酶活性。我们发现，在叶片生长过程中有两个关键阶段：（1）3年时细胞伸长开始，（2）6年时维管束分化。这与观察到最高端粒酶活性的年龄相吻合。因此表明端粒酶与细胞活动如伸长、分裂和细胞分化有关。同样，我们在营养生长期间检测到高活性，表明端粒酶也有助于[植物名称未给出]叶片中端粒的维持。
