From: Cowpea and abiotic stresses: identification of reference genes for transcriptional profiling by qPCR
Cowpea candidate reference genes evaluated by the ΔCt method and ranked according to expression stability for root dehydration and salt assays. Vu (Vigna unguiculata); β-TUB (beta-tubulin); UE21D (ubiquitin-conjugating enzyme E2 variant 1D); VuACT (actin); UNK (Phaseolus vulgaris unknown gene); FBOX (F-box protein); VuUBQ10 (polyubiquitin 10) and EF1-α (elongation factor 1-alfa)
