Plants, as sessile organisms, show a high degree of plasticity in their growth and development and have various strategies to cope with these alterations under continuously changing environments and unfavorable stress conditions. In particular, the floral transition from the vegetative and reproductive phases in the shoot apical meristem (SAM) is one of the most important developmental changes in plants. In addition, meristem regions, such as the SAM and root apical meristem (RAM), which continually generate new lateral organs throughout the plant life cycle, are important sites for developmental plasticity. Recent findings have shown that the prevailing type of alternative splicing (AS) in plants is intron retention (IR) unlike in animals; thus, AS is an important regulatory mechanism conferring plasticity for plant growth and development under various environmental conditions. Although eukaryotes exhibit some similarities in the composition and dynamics of their splicing machinery, plants have differences in the 3' splicing characteristics governing AS. Here, we summarize recent findings on the roles of 3' splicing factors and their interacting partners in regulating the flowering time and other developmental plasticities in .
植物作为固着生物，在其生长发育过程中表现出高度的可塑性，并具有多种策略来应对不断变化的环境和不利胁迫条件下的这些变化。特别是，茎尖分生组织（SAM）中从营养生长阶段到生殖阶段的花期转变是植物最重要的发育变化之一。此外，分生组织区域，如SAM和根尖分生组织（RAM），在植物整个生命周期中持续产生新的侧生器官，是发育可塑性的重要位点。最近的研究结果表明，与动物不同，植物中主要的可变剪接（AS）类型是内含子保留（IR）；因此，AS是一种重要的调控机制，赋予植物在各种环境条件下生长发育的可塑性。尽管真核生物在其剪接机制的组成和动态方面表现出一些相似性，但植物在调控AS的3'剪接特征方面存在差异。在这里，我们总结了关于3'剪接因子及其相互作用伙伴在调控开花时间和其他发育可塑性方面作用的最新研究结果。
