[Abstract]  Production of functional eukaryotic RNA is a very elaborate process that involves a complex interplay between transcription and various RNA processing activities, including splicing, 5’ capping, and 3’ cleavage and polyadenylation (Bentley, 2014). Accurate mapping of RNA ends provides a valuable tool to assess transcriptional and post-transcriptional events giving rise to different gene transcripts. The abundance of such transcripts most likely depends on exogenous and developmental cues, or mutations. In the reference plant Arabidopsis, perturbation of the HUA-PEP post-transcriptional regulatory factors (Rodríguez-Cazorla et al., 2015) leads to the accumulation of aberrant transcripts of the key floral homeotic gene AGAMOUS (AG) (Yanofsky et ... [摘要]  功能真核RNA的生产是非常复杂的过程,其涉及转录和各种RNA加工活性(包括剪接,5'加帽和3'剪切和聚腺苷酸化)之间的复杂相互作用(Bentley,2014)。 RNA末端的精确作图提供了评估产生不同基因转录物的转录和转录后事件的有价值的工具。这种转录物的丰度最可能取决于外源和发育线索或突变。在参考植物拟南芥中,HUA-PEP 转录后调节因子(Rodríguez-Cazorla等人,2015)的扰动导致保留内含子序列的关键花卉同源异源基因(AGO)( )(Yanofsky等人,1990)的异常转录物的积累。通过3'RACE反应测定,这样的错误转录物对应于在AG 内含子区发生的过早加工和聚腺苷酸化事件。在这里我们描述了一个适用于分析相对丰富的转录物以及用于检测可能易于快速更新的异常RNA种类的方案。同样地,此处适于拟南芥生殖组织的方法可用于表征来自其他器官(叶,根)和/或其它植物物种的RNA种类。我们提供我们的3'RACE程序的详细方案,包括四个主要部分:总RNA提取,RNA量测定和质量控制,RACE程序本身,和分离所得RACE产物用于克隆和测序。
