Shoot development consists of the production of lateral organs in predictable spatial and temporal patterns at the shoot apex. To properly integrate such programs of growth across different cell and tissue types, plants require highly complex and robust genetic networks. Over the last twenty years, the roles of small, non-coding RNAs (sRNAs) in these networks have become increasingly apparent, not least in vegetative shoot growth. In this review, we describe recent progress in understanding the contribution of sRNAs to the regulation of vegetative shoot growth, and outline persisting experimental limitations in the field.
茎尖发育包括在茎尖以可预测的空间和时间模式产生侧生器官。为了在不同的细胞和组织类型中正确整合这样的生长程序,植物需要高度复杂且强大的遗传网络。在过去二十年中,小的非编码RNA(sRNA)在这些网络中的作用变得越来越明显,尤其是在营养茎尖生长方面。在这篇综述中,我们描述了在理解sRNA对营养茎尖生长调控的贡献方面的最新进展,并概述了该领域仍然存在的实验局限性。
