Fig. 2

Differentially expressed genes (DEGs) in 6 groups (UZ vs. HZ, UD vs. HD, UN vs. HN, UZ vs. UN, UD vs. UN and UZ vs. UD). Red color represents up-regulated DEGs, green color represents down-regulated DEGs, and blue color represents non-differentially expressed genes. A Volcano plot showing DEGs in UZ vs. HZ. B Volcano plot showing DEGs in UD vs. HD. C Volcano plot showing DEGs in UN vs. HN. D Volcano plot showing DEGs in UZ vs. UN. E Volcano plot showing DEGs in UD vs. UN. F Volcano plot showing DEGs in UZ vs. UD. G Venn diagram of up-regulated DEGs in UZ vs. HZ, UD vs. HD and UN vs. HN and overlapping of the three groups. H Venn diagram of down-regulated DEGs in UZ vs. HZ, UD vs. HD and UN vs. HN and overlapping of the three groups. I Venn diagram of up-regulated DEGs in UZ vs. UN, UD vs. UN and UZ vs. UD and overlapping of the three groups. J Venn diagram of down-regulated DEGs in UZ vs. UN, UD vs. UN and UZ vs. UD and overlapping of the three groups
