Fig. 6From: Tissue-specific Transcriptome analysis reveals lignocellulose synthesis regulation in elephant grass (Pennisetum purpureum Schum)The heat maps of the expression pattern of cellulose synthase genes and lignin synthesis-related genes at different developmental stages of elephant grass stems. a Heat map of the expression pattern of 27 cellulose synthase genes. b, c, d, e, f Heat map of the expression pattern of some lignin synthesis-related genes. The grid with four different colors shows the absolute expression of genes, which are represented by different scale levels 2, 1, 0, − 1, and − 2, respectively. PAL: Phenylalanine Ammonia-Lyase; C4H: Cinnamic Acid4-Hydroxylase; CCR: Cinnamoyl-CoA Reductase; CAD: Cinnamyl Alcohol Dehydrogenase; F5H: FerulicAcid5-Hydroxylase; CoAOMT: Caffeoyl-CoAO-methytransferase; COMT: 5-Hydroxyferulic Acid O-Methyltransferase/Bispecific Caffeic AcidBack to article page
