genomes: 37181

One row per species (2,634 genomes) — start here to look up an organism. Each row carries its minor-intron verdict (u12_status), high-confidence and total U12-type intron counts, snRNA status, and proteome completeness (BUSCO); click the taxonomy_id or species name to open its full genome page.

Splice-site logos for Budorcas taxicolor

Rendered in the browser from motif_pwm counts via the Schneider-Stephens / WebLogo 3 information formula. The U12-type set control in the filter bar above switches the U12-type population — in these logos and every distribution chart below — between high-confidence calls (adjusted score ≥ 90) and motif-positive introns (p_motif ≥ 0.5: every intron whose splice-signal motif is U12-like, even where the genome made few or no calls). U2-type is the fixed genome-wide background.

Motif-score model for Budorcas taxicolor

intronIC's per-species tail model: the U2-type (major) background motif-score distribution (gray, log-scaled) in p_motif space, its extrapolated exponential tail (dashed — how far U2-type scores are expected to reach by chance), and the U12-type calls (green, p_motif ≥ 0.9). Calls sitting far to the right of the U2-type tail are the evidence for a genuine minor-spliceosome population.

5′SS vs BPS motif scores for Budorcas taxicolor

Every intron's raw 5′ splice-site vs branch-point motif score (log-odds, robust-standardized per genome). The U2-type (major) background is a log-scaled density (far too many introns to plot individually); U12-type calls are points, colored by confidence like intronIC (green > 90, amber / red = lower tiers set from the per-genome score spread). Minor introns separate into the high-score corner.
