Fig. 5From: Selection and validation of appropriate reference genes for RT–qPCR analysis of Nitraria sibirica under various abiotic stressesRelative expression of NsP5CS at 0, 3, 6, 12, 24, and 48 h following stress treatment using the selected reference genes for normalization. The validated reference gene(s) used as normalization factors were the two most stable reference genes (alone or in combination) and the two most unstable reference genes in different treatment groups. Error bars show the standard error calculated from three biological replicatesBack to article page
