Fig. 2

Hierarchical clustering of DEGs between thrips resistance of resistant alfalfa cultivar GN-1 and susceptible cultivar WL323. Each line in the figure represents a gene, with the columns representing thrips exposed GN-1 (R + T), unexposed GN-1 (R-T), thrips exposed WL323 (S + T) and unexposed WL323 (S-T). Red bands indicate up-regulated genes while green bands indicate down-regulated genes
