| Abstract | Abstract Quantitative real-time polymerase chain reaction (qRT-PCR) is a sensitive and widely used technique for quantifying gene expression levels, and its accuracy depends on the reference genes used for data normalization. To date, no reference gene has been reported in the nutritious and functional vegetable okra (Abelmoschus esculentus L.). Herein, 11 candidates of reference genes were selected and evaluated for their expression stability in okra in different tissues at different developmental stages by using three software algorithms (geNorm, NormFinder, BestKeeper) and a web-based tool (RefFinder). Among them, eukaryotic initiation factor 4 alpha (eIF4A) and protein phosphatase 2A (PP2A) showed the highest stability, while TUA5 had the lowest stability. The combined usage of these two most stable reference genes was sufficient to normalize gene expression in okra. Then, the above results were further validated by normalizing the expression of the cellulose synthase gene CesA4. This work provides appropriate reference genes for transcript normalization in okra, which will facilitate subsequent functional gene research on this vegetable crop. |
