3' end processing and mRNA polyadenylation is a vital aspect of gene expression in eukaryotes, and also a step at which expression may be regulated. A spate of recent research in plants links different subunits of the polyadenylation complex with growth and development. These reports provide insight into mechanisms by which APA may be regulated, and perhaps into mechanisms by which pre-mRNAs are processed and polyadenylated. In this review, several of these recent reports are discussed, with the purpose of highlighting novel features of mRNA 3' end formation in plants and also developing broad themes that connect APA with plant growth, development, and responses to the environment. This article is categorized under: RNA Processing > 3' End Processing RNA in Disease and Development > RNA in Development.

植物中的mRNA 3'末端形成：与生长，发育和环境响应的新型联系。

3'末端加工和mRNA聚腺苷酸化是真核生物中基因表达的重要方面，并且也是调节表达的步骤。一系列最近的植物研究将聚腺苷酸化复合物的不同亚基与生长和发育联系在一起。这些报告提供了对可能调节APA的机制的了解，也许还提供了对前mRNA加工和聚腺苷酸化的机制的了解。在这篇综述中，讨论了这些最新的报道中的一些，目的是突出植物中mRNA 3'末端形成的新特征，并提出将APA与植物生长，发育和对环境的反应联系起来的广泛主题。本文归类于：RNA加工> 3'末端加工RNA在疾病与发育中> RNA在发育中。
