Table S1 - Validation of Reference Genes in Solenopsis invicta in Different Developmental Stages, Castes and Tissues

Ranking of reference genes by stable values of S. invicta. Genes were ranked by the stable values obtained with three softwares (geNorm, BestKeeper, Normfinder) based on the gene expression stability in different developmental stages, castes and tissues. M value: stability measure value. The gene with the lowest M value denotes the most stably expressed gene. SD mentioned standard deviation of threshold cycle (Ct) value. Any studied gene with the SD higher than 1 can be considered inconsistent and not suit to be reference gene. Stability value: Lower scores denote greater transcript stability and suitability as a reference gene. (DOC)
