Series GSE112441 Query DataSets for GSE112441
Status Public on Aug 08, 2019
Title Gene expression profiling by RNA-seq of wild-type, fpa mutant, bdr1 mutant, bdr2 mutant, bdr3 mutant and bdrs triple mutant Arabidopsis seedlings
Organism Arabidopsis thaliana
Experiment type Expression profiling by high throughput sequencing
Summary We analyzed by RNA-seq the transcriptome of 8-day old Arabidopsis thaliana seedlings for wild-type (Col-0), single mutants for BDR proteins (bdr1/AT5G25520 ; bdr2/AT5G11430 or bdr3/AT2G25640), single mutant for FPA (fpa/AT2G43410, line fpa-7) or a triple mutant of all three BDR proteins (bdrs: cross of bdr1/AT5G25520 mutant SALK_142108C, bdr2/AT5G11430 mutant CS852350 and bdr3/AT2G25640 mutant SALK_059905). We identified hundreds of genes differentially expressed between wild-type and bdrs triple mutant and a significant overlap in DE genes with the fpa mutant. We also analyzed the binding of BDR1 and BDR2 as well as RNA polymerase II and histone marks by ChIP-seq in wild-type, bdrs and fpa-deficient seedlings. Our data support a role of BDRs as negative elongation factors. They bind on the gene body and regulate the expression of genes involved in defense response pathways. Strikingly, by modulating 3' pausing of RNA polymerase II and possibly contributing to gene looping, they also protect a number of genes from transcriptional interferences originating from a highly expressed upstream tandem gene. Thus BDRs proteins are negative elongation factors that act as transcriptional "gatekeepers" in the Arabidopsis thaliana genome.
Overall design mRNA profiles in 8-day old seedlings from wild-type (Col0), bdr single mutants (bdr1/AT5G25520 ; bdr2/AT5G11430 or bdr3/AT2G25640), fpa single mutant (fpa/AT2G43410) or bdr triple mutant were generated by deep sequencing, in triplicates, on Illumina NextSeq500
