  1. aBiotype comparison on alfalfa cultivars G9 (Gannong No. 9), G3 (Gannong No. 3), Q (Qingshui) and L (Longzhong)
  2. bOnly pathways with p-value or q-value < 0.05 were presented
  3. cThe q-value is a natural pFDR (positive false discovery rate) analogue to the p-value. KEGG pathways with q-value < 0.05 were defined as significantly enriched pathways
