Fig. 6From: Genome-wide characterization of tea plant (Camellia sinensis) Hsf transcription factor family and role of CsHsfA2 in heat toleranceExpression profiles of CsHsf genes in tea plants (C. sinensis cv. ‘Tieguanyin’) exposed to (a) drought (25% polyethylene glycol 6000) and (b) salt (200 mM NaCl) treatments. HemI software [56] was used to generate the heatmap. The heatmap of CsHsf expression based on the transcriptome data [47]. The color bar represents the normalized transcript per million (TPM) values (log10-transformed fold-changes). Red and blue colors indicate up- and down-regulated genes and the gray represents no expression. Detailed TPM values are listed in Additional file 5: Table S4Back to article page
