Transcript analysis of the CASP family genes in the different tissues of G. arboretum varieties. Expression levels were shown as log2(RPKM). The heat map was constructed using TBtools based on the expression data. The hierarchical clusters were generated according to the characteristics of CASP genes expression in different tissues. The yellow box displays genes specifically enriched in roots. The green colors indicate low expression levels, while red represents high expression levels. The gene expression data of each sample has three replicates, with three samples collected for each
