Hierarchical clustering analysis of 53 selected genes based on their gene expression patterns. Analysis of expression profiles of 53 ESTs (Additional File 4) in PUSABGD72 and ICCV2 with and without water-deficit stress. (A), ESTs were grouped into four clusters based on their expression profiles in PUSABGD72. The expression profile of individual gene in the cluster is denoted by grey line and the mean expression profile is depicted by pink line. The number of genes in each cluster is given in the left upper corner and the cluster number is given in the right lower corner. Detail information of genes within each cluster is elaborated in Additional File 5 and 6. (B), the comparative expression profiles of 53 ESTs in PUSABGD72 and ICCV2.
