Serrate modulates N6-Methyladenosine (m6A) RNA modification in Arabidopsis

ABSTRACT: N6-methyladenosine (m6A) is the most common prevalent internal modifications found in many of the eukaryotic mRNA and plays an important role in RNA metabolism including pre-mRNA processing, mRNA stability, RNA splicing, RNA export and nuclear retention. Serrate is a component of the Dicer complex, plays as a key factor in RNA metabolism. We here reported SERRATE acts as a key regulator of mRNA m6A modification in Arabidopsis. Loss function of SE results in significant global m6A level reduction in the se-1 mutant comparing to the Col-0. SE positively regulates the transcription of MTA and MTB. In addition, SE physically interacts and functionally works with the m6A writer complex MTA and MTB which affects the binding of m6A methylase to mRNA. Taking together, our data provides a molecular framework that SE modulates m6A mRNA modification in Arabidopsis.

Arabidopsis Messenger RNA N6-methyladenosine Demethylation Regulates Plant Development

Project description:N6-methyladenosine (m6A) is the most abundant internal modification in the messenger RNA (mRNA) of all higher eukaryotes. This modification has been shown to be reversible in mammals; it is installed by a methyltransferase heterodimer complex of METTL3 and METTL14 bound with WTAP, and reversed by iron(II)- and Î±-ketoglutarate-dependent demethylases FTO and ALKBH5. This modification exhibits significant functional roles in various biological processes. The m6A modification as a RNA mark is recognized by reader proteins, such as YTH domain family proteins and HNRNPA2B1; m6A can also act as a structure switch to affect RNA-protein interactions for biological regulation. In Arabidopsis thaliana, the methyltransferase subunit MTA (the plant orthologue of human METTL3, encoded by At4g10760) was well characterized and FIP37 (the plant orthologue of human WTAP) was first identified as the interacting partner of MTA. Here we report the discovery and characterization of reversible m6A methylation mediated by AtALKBH10B (encoded by At4g02940) in A. thaliana, and noticeable roles of this RNA demethylase in affecting plant development and floral transition. Our findings reveal potential broad functions of reversible mRNA methylation in plants. m6A peaks were identified from wild type Columbia-0 and atalkbh10b-1 mutant in two biological replicates

Programmable RNA N6-methyladenosine editing with CRISPR/dCas13a in plants

Project description:N6-methyladenonsine (m6A) is the most prevalent modification on mRNA and plays critical roles in mRNA processing and metabolism. However, how the m6A modification on individual gene of interest regulates gene function and the links to phenotypic outcome in plants are mostly unknown. Here, we described the construction and characterization of programmable m6A editing tools by fusing the m6A writer, core catalytical domain of MTA and MTB complex, and eraser, ALKBH5, to catalytically dead Cas13a (dCas13a), respectively, for targeting methylation and demethylation of specific mRNA. We demonstrated that our m6A editors could efficiently and specifically add and remove the m6A modification on specific RNA transcript in both Nicotiana benthamiana and Arabidopsis. Moreover, targeting SHORT-ROOT (SHR) transcript with methylation editor could significantly increase its m6A levels with limited off-target effects and enhance its expression, giving rise to induced plant growth with enlarged leaf size and root, increased plant height, plant biomass and total grain weight in Arabidopsis. Collectively, these findings suggest that our programmable m6A editing tools can be applied to study m6A modification of specific genes in plants, and might also have great potential applications for crop improvement in future

Long Intergenic Noncoding RNAs regulated by SERRATE, CBP20 and CBP80

Project description:Long intergenic noncoding RNAs (lincRNAs) transcribed from intergenic regions play important roles in key biological processes.Analysis of published transcriptom datasets suggested some lincRNAs may be regulated by SERRATE,CBP20 and CBP80 in Arabidopsis. To further investigate the regulation, we use Arabidopsis lincRNA arrays v1 to detect lincRNA expression in se-2 and cbp20/80 double mutants.We found the expression levels of 940 lincRNAs (20%) out of the 4,634 lincRNAs with probes in array were significantly alerted in all mutants (P-value of eBays ANOVA < 0.05 & fold change of signal intensity > 2). This group included 525 up-regulated and 415 down-regulated lincRNAs. Seedlings(Col-0), Seedlings(se-2), Seedlings(cbp20,80 double mutant) x 3 biological replicates

PRP4KA phosphorylates Serrate/Ars2 for degradation vs 20S proteasome to fine-tune RNA processing

Project description:We examined global expression profiles of 3-week-old prp4k3(amiR-PRP4K3) leaves compared to Col-0 using illumina sequencing. PRP4KA and its paralogs interact with Serrate (SE), a key factor in miRNA metabolism.phosphorylation of SE via PRP4KA can quickly clear accumulated SE to secure its proper amount. This study provides new insight into how protein phosphorylation regulates RNA metabolism through controlling homeostasis of SE accumulation in miRNA metabolism.

Dual roles of the nuclear cap binding complex and SERRATE in pre-mRNA splicing and microRNA processing in Arabidopsis

Project description:The processing of Arabidopsis thaliana microRNAs (miRNAs) from longer primary transcripts (pri-miRNAs) requires the activity of several proteins, including DICER-LIKE1 (DCL1), the double stranded RNA binding protein HYPONASTIC LEAVES1 (HYL1), and the zinc finger protein SERRATE (SE). It has been noted before that the morphological appearance of weak se mutants is reminiscent of plants with mutations in ABH1/CBP80 and CBP20, which encode the two subunits of the nuclear cap-binding complex. We report that, like SE, the cap-binding complex is necessary for proper processing of pri-miRNAs. Inactivation of either ABH1/CBP80 or CBP20 results in decreased levels of mature miRNAs accompanied by increased levels of pri-miRNAs. Whole genome tiling array analyses reveal that se, abh1/cbp80 and cbp20 mutants also share similar pre-mRNA splicing defects, leading to the accumulation of many partially spliced transcripts. This is unlikely to be an indirect consequence of improper miRNA processing or other mRNA turnover pathways, since introns retained in se, abh1/cbp80 and cbp20 mutants are not affected by mutations in other genes required for miRNA processing or for non-sense-mediated mRNA decay. Taken together, our results uncover dual roles in splicing and miRNA processing that distinguish SE and the cap-binding complex from specialized miRNA processing factors such as DCL1 and HYL1. Keywords: Tiling array analysis of RNA populations from wild type, se, abh1 and cbp20 mutants

Transcription profiling of wild type and serrate-1 mutant Arabidopsis seedlings to investigate regulation of miRNA levels

Project description:microRNAs function as sequence-specific guides to regulate genes by post-transcriptional gene silencing. Many miRNAs are involved in the control plant development by regulating the accumulation of transcripts encoding transcription factors. This causes pleiotropic developmental phenotypes of mutants defective in miRNA accumulation, such as dcl1, hen1, hyl1 and ago1. The serrate-1 (se-1) mutant of Arabidopsis also exhibits a highly pleiotropic phenotype which overlaps with phenotypes of mutants defective in miRNA accumulation. It has been proposed that SE functions specifically in miRNA-mediated repression of the leaf polarity genes PHABULOSA and PHAVOLUTA. Microarray analysis of transcript levels in se-1 compared to wild-type however revealed upregulation of many genes known to be targets of miRNA regulation. We show that SE is a general regulator of miRNA levels probably controlling processing of pri-miRNA to miRNA.
