Statistics of DEGs identified in maturing stem tissue in different sugarcane genotypes treated with ethephon. Venn diagram of pairwise comparisons DEGs in three genotypes (a) before ethephon treatment (b) after ethephon treatment and (c) before and after ethephon treatment. (d) Number of up-regulated and down-regulated DEGs before and after ethephon treatment in 3 genotypes. (e) Heatmap of DEGs in 3 genotypes before and after ethephon treatment. Expression values are presented as RPKM normalized log₂ transformed counts. Red and blue colors indicate up- and down- regulated transcripts, respectively. CK- check (water control), T- ethephon treatment, HS: high-sugar variety, MS: medium-sugar variety, LS: low-sugar variety
