摘要: 静止中心是高等植物根尖分生组织和其中的干细胞微环境中的组织中心，低细胞分裂活动是其标志性特征。虽然研究发现该特性受到非常严格与精确的调控，但其生物学意义目前并不清楚。本文列举了拟南芥中3个静止中心细胞分裂并不影响根生长发育的例子，旨在引发有兴趣的研究工作者开展进一步研究或进行进一步探讨与思考。
Abstract: The quiescent center (QC) serves as the organizing center in the root apical meristem of higher plants and maintains the stem cell niche. Its hallmark feature is low mitotic activity. Although studies have shown that this characteristic is under strict and precise regulation, its biological significance remains unclear. This article presents three examples in Arabidopsis thaliana where QC cell division does not affect root growth and development, aiming to inspire further research and discussion among interested scientists.
