Fig. 9From: Multiple responses contribute to the enhanced drought tolerance of the autotetraploid Ziziphus jujuba Mill. var. spinosaPutative model of the internal mechanisms of superior tolerance after chromosomal doubling. Gray blocks represent the missing value caused by low expression and large repetition difference. Each heatmap represents the differential expression level based on log2 (Fold change) value. Gradient colour bar code at the top indicates log2 (Fold change) values with up-regulated genes represented by positive values and down-regulated genes represented by negative valuesBack to article page
