Cell cycle dependent regulation and function of Argonaute 1 in plants [small RNA-seq] |
| Organism |
Nicotiana tabacum |
| Experiment type |
Non-coding RNA profiling by high throughput sequencing

| Summary |
The RNA silencing (RNAi) is a biological process, which plays a key role in a wide range of eukaryotes, such as gene expression regulation, transposable elements control and antiviral defense. In human, several studies showed that miRNAs and AGO2 are involved in the regulation of the cell cycle. Indeed, many cell cycle regulators such as cyclins, CDKs, CDK inhibitors, RBR proteins or E2F transcription factors have been identified as miRNA targets. Transcriptional data suggest that these cell cycle miRNAs are differentially accumulated during cell cycle progression and that misregulation of some could lead to proliferative diseases. However, in plants, almost nothing is known about the cell cycle regulation through miRNAs. Unpublished datas from the lab suggest that the Arabidopsis AGO1, which is the most important Argonaute for miRNA-mediated gene regulation, is essential for cell proliferation. In order to investigate the role of AGO1 during cell cycle, we set up a system based on cell cycle synchronization of tobacco BY-2 cell suspensions expressing a GFP-fused AGO1. We sequenced small RNAs from S, G2, M and G1 phases of synchronized cells from total RNA extract and GFP-AGO1 co-purified small RNAs, and investigate whether putative cell cycle specific miRNAs can be highlighted.

| Overall design |
5 different replicates of small RNA-seq from AGO1IP and total RNA are included in this study. They correspond to 4 different phases of the cell cycle.
