Abstract Noncoding RNA (ncRNA), such as microRNA (miRNAs), long ncRNAs (lncRNAs), and circular RNAs (circRNAs) play roles in plant growth, development, and response to environmental cues via diverse manners. Splicing factors are critical for precursor messenger RNAs (pre-mRNAs) splicing and alternative splicing. Strikingly, over the past few years, an increasing number of studies demonstrated that splicing factors couple splicing to other processes, such as ncRNA biogenesis, nuclear retention, and cytoplasmic export of various RNAs, and even translation. Here, we review the current status of the noncanonical functions of splicing factors in the ncRNAs processing, retention and export of RNAs, and translation in plants.

RNA 代谢中剪接因子的非典型函数

摘要 非编码 RNA (ncRNA)，例如 microRNA (miRNA)、长 ncRNA (lncRNA) 和环状 RNA (circRNA)，通过多种方式在植物生长、发育和对环境线索的响应中发挥作用。剪接因子对于前体信使 RNA (pre-mRNAs) 剪接和选择性剪接至关重要。引人注目的是，在过去几年中，越来越多的研究表明剪接因子将剪接与其他过程结合起来，例如 ncRNA 生物发生、核保留和各种 RNA 的细胞质输出，甚至翻译。在这里，我们回顾了剪接因子在 ncRNA 加工、RNA 保留和输出以及植物翻译中的非规范功能的现状。
