Project description:au12-06_cpsf30 - cpsf30 mips1 transcriptome - How a mutation in the CPSF30 is able to suppress the cell death phenotype observed in the mips1-1 Arabidopsis mutant? - All the plants were cultivated in the same hanging conditions 10days in "short Days" then in long Days. The takings were later made 4days in "long Days" what corresponds to the appearance of the symptoms of cellular death at the mutant mips1-1. On the other hand, the gene CPSF30 codes for two transcribed. We have a double mutant mips1 cpsf30 complemented with the transcribed young.

Project description:As the most ubiquitous internal modification of eukaryotic mRNA, m6A (N6-methyladenosine) modification plays a vital role in almost every aspect of mRNA metabolism. However, the evidence of m6A in regulating the alternative polyadenylation (APA) is limited. APA is controlled by a large protein-RNA complex with many components including CPSF30. Arabidopsis CPSF30 has two isoforms, the longer one named CPSF30-L containing an additional YTH (YT512-B Homology)-domain in the C terminus, which is unique in plant. In this study, we revealed that m6A modification directly regulated APA, by proving the capability of Arabidopsis CPSF30-L YTH domain binding to m6A substrate by using in vitro assay and structural studies. We observed that extensive genes shifted their poly(A) sites in cpsf30-2 and found that numerous genes altered polyadenylation site (PAS) that correlated well with previously identified m6A peaks, indicating that genes carry m6A modification are prone to be regulated by APA. Moreover, we found that several important genes involved in nitrate metabolism are amongst those genes with APA site alteration in cpsf30-2.And we could rescue these APA and nitrate metabolism defects by introducing the wild-type CPSF30-L, but not by m6A-binding defective mutants (W259A, W310A or Y319A), which explained the nitrogen signaling defects of cpsf30-2 discovered previously. Taken together, our results demonstrated that m6A modification could directly regulate APA in Arabidopsis and revealed the function of m6A reader CPSF30-L in nitrate signaling by controlling APA regulation. This study will shed new lights on the roles of m6A modification during RNA 3’-end processing in plant development.
Project description:Purpose:The goals of this study are to compare transcriptome of amp1-32 mutant with that of wild-type Columbia-0 plant and to identify genes whose expression are tightly regualted by AMP1 in Arabidopsis. Methods: mRNA profiles of 3-week-old wild-type Col-0 and amp1-32 mutant plants were generated by deep sequencing, in duplicate, using Illumina HiSeq2000. The sequence reads that passed quality filters were analyzed at the transcript isoform level with a method : TopHat followed by Cufflinks. Results: Using an optimized data analysis workflow, we mapped about 30~53 million sequence reads per sample to the Arabidopsis genome (TAIR10). From the 2 biological replicates, we detected 135 up-regulated genes, and 36 down-regulated genes, in the amp1-32 mutant plant. Conclusions: Our study represents the first detailed analysis of transcriptome of amp1 mutant plants, with biologic replicates. Our results show that AMP1 protein had weak, but significant, effects on transcription of genes important for plant development and responses to stresses.
