TATA‐box motifs identified by Smar2C2.

Sequence logos show sequence patterns surrounding the transcription start site (TSS), including possible initiator element (Inr) and TATA‐box sequences (a). The TATA‐box motifs discovered close to the TSS display precise positional enrichment relative to the TSS (c), and are found in the classic region from positions −28 to −35 of the promoter (c, d). TATA‐box motifs discovered in the highest expression decile show some sequence deviation from the classic TATA‐box motif, with Oryza sativa (rice), Sorghum bicolor (sorghum) and Triticum aestivum (wheat) displaying enrichment for a C preceding the more classic TA‐rich motif (b).
