Fig. 2From: Selection and validation of appropriate reference genes for RT–qPCR analysis of Nitraria sibirica under various abiotic stressesExpression stability values (M) of 10 candidate reference genes validated via the geNorm program. The least stable genes with higher M-values are on the left, and the most stable genes with lower M-values are on the right. SL and SR: Salt-treated leaves and roots, respectively; AL and AR: alkali-treated leaves and roots, respectively; DL and DR: drought-treated leaves and roots, respectively; CL and CR: cold-treated leaves and roots, respectively; HL and HR: heat-treated leaves and roots, respectively; ABL and ABR: abscisic acid-treated leaves and roots, respectivelyBack to article page
