Fig. 2From: Identification of defense related gene families and their response against powdery and downy mildew infections in Vitis viniferaHeat maps illustrating the differential expression patterns for defensive genes in Vitis vinfera. (a) PM-responsive defensive genes at time points of 0 h and 36 hpi. The gradient value of color mapping ranges from − 1 to + 1 (b) DM-responsive defensive genes at time points of 0 h, 1 dpi, 2 dpi and 3 dpi. The gradient value ranges from − 1.73 to + 1.73. Green color indicates declined expression level, red color indicates elevated expression levels, black color indicates no expression. PM and DM defensive genes are clustered in two groups indicated by gene names with blue and red colorBack to article page
