Fig. 3From: Comparative physiological and transcriptome analysis between potassium-deficiency tolerant and sensitive sweetpotato genotypes in response to potassium-deficiency stressHeatmap of stress-related hormone contents in two different K+-sensitive sweetpotato cultivars, Xu32 and NZ1, under normal (Control) and K+-deficient conditions (-K) for 2 weeks. The tested materials can be classified into three hormones, namely abscisic acid (ABA), jasmonic acid (JA), and salicylic acid (SA). Data shown are the means ± standard error (SE) (n = 3). The color scale varies from green to red, indicating relatively low and high hormone contents, respectivelyBack to article page
