Fig. 6From: Transcriptome analysis reveals candidate genes related to phosphorus starvation tolerance in sorghumHeatmap of the candidate genes involved in plant hormone signal transduction. The log2 fold change of the candidate genes involved in plant hormone signal transduction under low-P conditions compared with that under sufficient-P conditions in each section is represented by a color scale consisting of red (upregulated), white (not regulated) and green (downregulated)Back to article page
