Fig. 6From: Transcriptomic and physiological analysis of the response of Spirodela polyrrhiza to sodium nitroprussideExpression pattern of genes associated with TFs under SNP treatment in S. polyrrhiza. A ERF family; B BHLH family; C WRKY family; D NAC family. The expression level was Z score normalized. The colour gradient (green to red) corresponds to the gene expression levels (low to high). Each row represents a gene, with its name given in parenthesesBack to article page
