Experiment / E6FTNE62FWhole-Genome STARR-seq (WHG-STARR-seq)

Nipponbare stem-protoplast whole-genome STARR-seq

Global Quantitative Mapping of Enhancers in Rice by STARR-seq

Randomly fragmented genomic DNA from rice cultivar Nipponbare was cloned into an episomal STARR-seq reporter and transfected into protoplasts isolated from green stem tissue of two-week-old seedlings. RNA output and input plasmid DNA were sequenced 16 hours after transfection in two independent biological replicates, yielding the shared enhancer set represented here.

Perturbation & assay details

Basal / Untreated

Episomal pBI221 reporter containing a 35S mini promoter and GFP/intron reporter architecture with NOS polyadenylation elements. Approximately 700-bp genomic fragments were tested in rice stem protoplasts; plasmid input and self-transcribed RNA were recovered after 16 hours and sequenced as 150-bp paired-end libraries on Illumina HiSeq X Ten.

Column dictionary · 25 definitions
element_id
Stable identifier assigned to each shared merged rice STARR-seq enhancer.
chromosome
Rice chromosome name exactly as supplied by the GEO merged peak file.
start_bp
Start coordinate of the shared merged enhancer, preserved from GEO and Supplementary Table S3.
end_bp
End coordinate of the shared merged enhancer, preserved from GEO and Supplementary Table S3.
dhs_sensitivity
Supplementary Table S3 annotation indicating whether the enhancer overlaps a DNase I hypersensitive site (With DHS or Without DHS).
epigenetic_cluster
Author-defined epigenetic cluster assignment from Supplementary Table S3 (clusters 1-8).
rep1_peak_count
Number of replicate-1 author-filtered peak calls overlapping the shared merged enhancer.
rep1_peak_start_bp
Start coordinate of the representative replicate-1 peak call, selected by highest enrichment.
rep1_peak_end_bp
End coordinate of the representative replicate-1 peak call, selected by highest enrichment.
rep1_sample_cov
STARR-seq cDNA/sample coverage for the representative replicate-1 peak (GEO sampleCov).
rep1_control_cov
Input plasmid/control coverage for the representative replicate-1 peak (GEO controlCov).
rep1_pvalue
Unadjusted peak-enrichment P value for the representative replicate-1 call (GEO pVal).
rep1_bonferroni_pvalue
Bonferroni-corrected peak-enrichment P value for the representative replicate-1 call (GEO CpVal).
rep1_enrichment
STARR-seq cDNA-to-input enrichment for the representative replicate-1 call.
rep2_peak_count
Number of replicate-2 author-filtered peak calls overlapping the shared merged enhancer.
rep2_peak_start_bp
Start coordinate of the representative replicate-2 peak call, selected by highest enrichment.
rep2_peak_end_bp
End coordinate of the representative replicate-2 peak call, selected by highest enrichment.
rep2_sample_cov
STARR-seq cDNA/sample coverage for the representative replicate-2 peak (GEO sampleCov).
rep2_control_cov
Input plasmid/control coverage for the representative replicate-2 peak (GEO controlCov).
rep2_pvalue
Unadjusted peak-enrichment P value for the representative replicate-2 call (GEO pVal).
rep2_bonferroni_pvalue
Bonferroni-corrected peak-enrichment P value for the representative replicate-2 call (GEO CpVal).
rep2_enrichment
STARR-seq cDNA-to-input enrichment for the representative replicate-2 call.
mean_replicate_enrichment
Arithmetic mean of the representative replicate-1 and replicate-2 enrichment values.
rep2_to_rep1_enrichment_ratio
Representative replicate-2 enrichment divided by representative replicate-1 enrichment.
passes_shared_replicate_qc
Boolean flag indicating that both representative replicate calls satisfy enrichment >=1.3 and corrected P <0.001 and belong to the shared merged set.

Quality control

The processed GEO peak files already apply the authors' QC: uniquely mapped paired-end reads were retained, PCR duplicates were removed, BasicSTARRseq peaks were Bonferroni-corrected, and calls were required to have enrichment >=1.3 and corrected P <0.001. The paper retained only enhancer peaks detected in both biological replicates; the packaged table therefore contains the 9,642 author-provided shared merged intervals. When multiple filtered peak calls overlapped one merged interval in a replicate, the highest-enrichment call was used for that replicate's representative metrics and the number of overlapping calls was retained in *_peak_count.

Curation notes

This is a region-focused whole-genome enhancer screen, not an allele- or variant-focused MPRA. The table preserves the 9,642 shared intervals and author annotations one-for-one; it does not include raw sequencing reads. GEO and Supplementary Table S3 use matching start/end values, so coordinates were not re-based or normalized. The source GEO merged file contains a small number of overlapping adjacent records, which were retained as supplied. The biosample is represented as rice stem-derived primary protoplasts; no unambiguous requested UBERON or terminal Cell Ontology identifier was determined for this plant preparation, so UNMAPPED:rice_stem_protoplasts is used.
