Evolution of DNA Binding Sites of a Floral Master Regulatory Transcription Factor

Mol Biol Evol
PMCID: 4693976
PMID: 26429922
DOI: 10.1093/molbev/msv210

[…] ned. Sequence reads mapping to the plastid and mitochondrial genomes were eliminated. For A lyrata, only reads mapping to the 9 longest scaffolds were retained (scaffold length > 1 Mb). The R package CSAR was used for peak calling for each biological replicate independently with default parameter values except for backg, which was set to 5 for all the analyses except AlySEP3 ChIP-seq replicate 1 w […]


Combinatorial activities of SHORT VEGETATIVE PHASE and FLOWERING LOCUS C define distinct modes of flowering regulation in Arabidopsis

Genome Biol
PMCID: 4378019
PMID: 25853185
DOI: 10.1186/s13059-015-0597-1

[…] e Bioconductor package NarrowPeaks []. Only MACS peaks also detected by NarrowPeaks were considered for further processing. Final sets of peaks were annotated to TAIR10 using the Bioconductor package CSAR []. Analysis of peak distribution over exon, intron, enhancer, proximal promoter, 5’ UTR and 3’ UTR was done in R using ChIPpeakAnno []. Proximal promoter and immediate downstream were considered […]


Cell elongation is regulated through a central circuit of interacting transcription factors in the Arabidopsis hypocotyl

PMCID: 4075450
PMID: 24867218
DOI: 10.7554/eLife.03031.025

[…] es was carried out on an Illumina HiSeq 2000. Sequences in Solexa FASTQ format were mapped to the Arabidopsis genome, TAIR9, using SOAP2. ARF6 binding peaks were identified using ChIP-Seq analysis R (CSAR) software with parameters (backg = 10, norm = −1, test = 'Ratio', times = 1e6, digits = 2) (). Binding peaks with FDR < 0.01 were defined as the ARF6 binding peak and used in further analyses. Ge […]


Genome wide data (ChIP seq) enabled identification of cell wall related and aquaporin genes as targets of tomato ASR1, a drought stress responsive transcription factor

BMC Plant Biol
PMCID: 3923394
PMID: 24423251
DOI: 10.1186/1471-2229-14-29

[…] pret our high throughput DNA sequencing results. Our ChIP-seq data showed 225 peaks with different values of statistical significance. The results of ChIP-seq were also analyzed with Cisgenome [] and CSAR [], but these results gave false peaks and were thus discarded. Artifacts can arise because the annotated sequence of the tomato genome [] is not error-free, particularly regarding the copy numbe […]


Structural determinants of DNA recognition by plant MADS domain transcription factors

Nucleic Acids Res
PMCID: 3936718
PMID: 24275492
DOI: 10.1093/nar/gkt1172

[…] e reads were mapped to the Arabidopsis thaliana (TAIR9) genome using SOAPv2 (). Reads mapped to multiple regions or to the mitochondria or chloroplast genome were discarded. We modified the R package CSAR () to generate read-enrichment score values at each single-nucleotide position, without performing peak calling. This score represents the ratio between density of reads overlapping a given nucle […]


Practical Guidelines for the Comprehensive Analysis of ChIP seq Data

PLoS Comput Biol
PMCID: 3828144
PMID: 24244136
DOI: 10.1371/journal.pcbi.1003326

[…] equence such as GC content or mappability (BEADS ). Peaks are finally called above a user-defined SNR level. Models used for the statistical assessment of enriched regions (peaks) range from Poisson (CSAR ), local Poisson (MACS), negative binomial (CisGenome ) to zero-inflated negative binomial (ZINBA ), or even extend to more sophisticated machine learning modeling techniques such as Hidden Marko […]
