Comprehensive native plant core-promoter STARR-seq in tobacco leaves

Synthetic promoter designs enabled by a comprehensive analysis of plant core promoters

The Arabidopsis, maize, and sorghum comprehensive native-promoter libraries were transiently delivered to Nicotiana benthamiana leaves. Promoter scores are summarized for no-enhancer and 35S-enhancer libraries in dark or light conditions across two biological replicates.

Processed tables are specific to each experiment. Column names, units, measurements, and table structure are not standardized across the database. Check this experiment’s column definitions and quality-control notes before comparing or combining data.

Perturbation & assay details

35S enhancer absent/present; dark or 16 h light/8 h dark after Agrobacterium infiltration

The assay used the episomal pPSup plant STARR-seq reporter: a 170-bp promoter sequence (-165 to +5 relative to the annotated TSS) was cloned upstream of a maize or sorghum histone 5-prime UTR, an ATG, GFP, and a 12-bp random barcode. Libraries with and without the upstream CaMV 35S enhancer were measured by sequencing barcode-containing input plasmid DNA and reporter mRNA; two independent biological replicates were performed for each library condition.

Quality control

The authors discarded promoter-barcode subassemblies with fewer than 5 assembly reads and barcode observations with fewer than 5 input or output reads. The package retained 77,895 native promoter rows with a complete 170-bp sequence and at least one finite tobacco-leaf condition score after applying the WT/full-length construct filter; replicate-level scores are retained when available, and missing condition cells remain blank.

Curation notes

This table combines three source promoter species because the same tobacco-leaf assay system was used for each library. The assay organism is Nicotiana benthamiana; source promoter assemblies use Araport11, B73 RefGen v4, and NCBI_v3.43 annotations, so reference_genome is null at the combined-experiment level. Raw compact barcode counts and the authors' filtered subassemblies are retained under raw_data/source_counts and raw_data/filtered_subassembly_*.
