Heat maps of the genes involved in the sesquiterpene biosynthesis, JA pathway and oxygen metabolism in two germplasm resources. A Sesquiterpene biosynthesis and JA pathways. The enzymes were involved in the biosynthesis of sesquiterpene including acetoacetyl-CoA thiolase (AACT), hydroxymethylglutaryl-CoA synthase (HMGS), hydroxymethylglutaryl-CoA reductase (HMGR), mevalonate kinase (MK), phosphomevalonate kinase (PMK), mevalonate-diphosphate decarboxylase (MCD), farnesyl pyrophosphate synthase (FPPS), Geranylgeranyl pyrophosphate synthase (GPP), terpene synthase (TPs). 1-deoxy-D-xylulose-5-phosphate synthase (DXS), 1-deoxy-D-xylulose-phosphate reductoisomerase (DXR), 4-diphosphocytidyl-2C-methyl-D-erythritol kinase (CMK), 2C-methyl-D-erythritol 2,4-diphosphate synthase (MECS), 1-hydroxy-2-methyl-butenyl 4-diphosphate synthase (HDS), 1-hydroxy-2-methyl-butenyl 4-diphosphate reductase (HDR). The genes were involved in JA pathway including allene oxide cyclase (AOC), allene oxide synthase (AOS), 13-lipoxygenase (13-LOX), OPDA reductase (OPR2), jasmonate resistant synthase (JAR), cytochrome p450 (CYP450), coronatine insensitive (COI1), jasmonate ZIM-domain protein (JAZ), basic helix–loop–helix transcription Factor (MYC2). B The hierarchical clustering was carried out to Heat-map cluster analysis on the FPKM value of genes. Heat map shows values (− 1.5 to 1.5) about homogenization processing (Z-score) on rows ranging from blue (low expression) to red (high expression). HKB represents the ordinary A. sinensis, WZX represents Chi-Nan germplasm. H represents Healthy, W represents Wounded
