Project description:Nonsense-mediated mRNA decay (NMD) is a conserved mRNA quality control mechanism that identifies and destroys aberrant mRNAs that contain premature termination codons (PTCs). The NMD core comprises seven proteins, from SMG1 to SMG7. Arabidopsis has orthologues of most of these proteins. Studies on yeast, Drosophila, Humans and Arabidopsis reveal that NMD not only functions to target PTC-containing mRNAs but also acts as a global regulator of gene expression. It has also been reported that the NMD pathway branches with some target genes being dependent on specific NMD factors. In order to determine the extent to which different NMD factors co-regulate or independently regulate Arabidopsis genes, transcriptome analysis of smg7b-1 mutants will be carried out and added to existent data of upf1, upf3 and smg5 NMD mutants for comparison. RNA will be extracted from 17 day-old mutant and wild type seedlings grown at 22-24 C under constant light.

Project description:The nonsense-mediated mRNA decay pathway (NMD) is a quality control mechanism that detects and degrades mRNAs that contain premature translation termination codons (PTCs), thus preventing the production of potentially harmful truncated proteins. NMD has been studied in a number of organisms including humans, yeast, Drosophila, C. elegans and recently Arabidopsis. Recently the NMD process has been shown to have a wider significance in regulating the levels of mRNA expression for a wide range of genes in yeast and Drosophila. Several genes have been found to be required for NMD in a variety of organisms, including UPF1 and UPF3. We have identified and characterised a number of alleles of UPF1 and UPF3 in Arabidopsis that are defective in NMD. By doing a transcriptomic analysis of two NMD mutants, upf1-1 and upf3-1, and wild type plants we aim to identify the subset of genes that are co-regulated by UPF1 and UPF3 and, therefore, by NMD in Arabidopsis. RNA will be extracted from 17-day-old mutant and wild type seedlings grown at 22-24 C under constant light.

Project description:Eukaryotic cells have evolved a mechanism called nonsense mediated mRNA decay (NMD) that detects and degrades aberrant mRNAs that contain premature termination codons (PTCs). NMD has recently acquired broader importance as it has been found to regulate not only aberrant mRNAs but also a great diversity of transcripts, including wild type genes in mammals, Drosophila and yeast. Seven proteins are the core of the NMD complex: SMG1, SMG2 (UPF1), SMG3 (UPF2), SMG4 (UPF3), SMG5, SMG6 and SMG7. Plants have orthologues of most of these proteins. We have identified and characterized a number of alleles of UPF1, UPF3 and SMG5 and made 35S:UPF2 RNAi (upf2i) transgenic plants, all of which share some phenotypic characteristics. Transcriptome analysis of upf1 and upf3 mutants has identified a subset of genes coregulated by UPF1 and UPF3 and, therefore, by NMD (unpublished data). By doing further transcriptome analysis on smg5 mutants and upf2i plants we aim to build a more robust subset of NMD targets in Arabidopsis. RNA will be extracted from 17 day-old mutant, transgenic and wild type seedlings grown at 22-24 C under constant light.
