*2.5. KEGG Enrichment of DEGs under Salt Stress 2.5. KEGG Enrichment of DEGs under Salt Stress* The KEGG pathway enrichment analysis were performed to identify the candidate pathways

The KEGG pathway enrichment analysis were performed to identify the candidate pathways involved in salt stress using KOBAS 2.0 [19]. The results showed that genes with KO number within 519 DEGs under salt stress were enriched in 48 KEGG pathways (Table S5). The top-four enriched pathways for DEGs in SC vs CK were 'Fatty acid elongation', 'Ribosome', 'Sphingolipid metabolism' and 'Flavonoid biosynthesis'. For up-regulated DEGs (Table S6), the most highly enriched pathways were 'Sphingolipid metabolism', 'Other glycan degradation', 'Brassinosteroid biosynthesis' and 'Citrate cycle (TCA cycle)' (Figure 5d). For down-regulated DEGs (Table S7), 'Ribosome', 'Fatty acid elongation', 'Flavonoid biosynthesis' and 'Phenylpropanoid biosynthesis' were the top-four enriched pathways (Figure 5d). involved in salt stress using KOBAS 2.0 [19].
