Analysis of the ASMT Gene Family in Pepper (Capsicum annuum L.): Identification, Phylogeny, and Expression Profiles

Figure 5

Expression profiles of CaASMT genes in response to abiotic stresses based on RNA-Seq in pepper. (a) Leaf under heat treatment conditions; (b) leaf under cold treatment conditions. Leaf tissue was collected from both heat- and cold-treated plants at 0, 0.5, 1, 3, 6, 12, and 24 hours posttreatment (HPT) and was named HL1 to HL6 and FL1 to FL6, respectively. CL0 represents the control group. All RNA-Seq datasets were obtained from the Pepper Informatics Hub (http://pepperhub.hzau.edu.cn/), and a detailed description of the samples is available from the Pepper Informatics Hub. The data were normalized based on the mean expression value of each gene in all identified tissues. Then, the log2-transformed RPKM values were used to obtain heat maps using the software MeV 4.9.0. Red and green boxes indicate the high and low expression levels of the CaASMT genes, respectively.
