Fig. 6From: Genome-wide characterization of NtHD-ZIP IV: different roles in abiotic stress response and glandular Trichome inductionHeat maps of NtHD-ZIP IVs gene expression under different hormones and abiotic stresses. qRT-PCR was performed to analyze the transcript level of NtHD-ZIP IVs, and the results were calculated by the 2-ΔΔCT method. L25 was selected as a control gene. The lowest transcript level at each treatment for each gene was set as 1Back to article page
