## Panel A — DEG bar chart（柱状图）
**Type:** Grouped bar chart. Y-axis: Number of DEGs. X-axis: three cultivars (CK, W6, W5). Two bars per cultivar: upregulated (orange #E67E22) vs downregulated (steel blue #2E86C1).

**Data:**
- CK: up=6,182 / down=5,065 (total 11,247)
- W6: up=1,721 / down=272 (total 1,993)
- W5: up=631 / down=215 (total 846)

**Label:** Above bars show "11,247", "1,993", "846" totals.
**Subtitle:** "Mid-stage vs early-stage DEGs (|log₂FC| > 1, FDR < 0.05)"

## Panel B — KEGG enrichment（水平柱状图）
**Type:** Horizontal bar chart. Y-axis: top 5 KEGG pathways. X-axis: gene count.

**Pathways (top to bottom):**
1. Plant hormone signal transduction — 163 genes (color: green #27AE60)
2. Plant–pathogen interaction — 101 genes (teal #1ABC9C)
3. Starch and sucrose metabolism — 63 genes (blue #2980B9)
4. Phenylpropanoid biosynthesis — 61 genes (purple #8E44AD)
5. Flavonoid biosynthesis — 38 genes (pink #C0392B)

**Subtitle:** "KEGG enrichment of upregulated genes in CK"

## Panel C — Attenuation comparison（柱状图或点图）
**Type:** Simple bar chart. Y-axis: Percentage of mid-stage response retained. X-axis: CK, W5, W6.

**Data:**
- CK → continues into late stage: 5,769 DEGs (51% of mid→early response)
- W5 → near-complete quiescence: 2 DEGs (0.2%)
- W6 → complete quiescence: 0 DEGs (0%)

**Colors:** CK = dark blue, W5 = light green, W6 = gray
**Annotation:** "51%" / "0.2%" / "0%" above each bar

**Subtitle:** "Late-stage transcriptional attenuation"
