Sumario: | The role of Melatonin in influencing diverse genes in plants has gained momentum in recent years and many reports have employed qRT-PCR for their quantification. Relative quantification of gene expression relies on accurate normalization of qRT-PCR data against a stably-expressing internal reference-gene. Although researchers have been using commonly available reference-genes to assess Melatonin-induced gene expression, but to-date, there have been no attempts to validate the reference-gene stability under Melatonin-supplementation in planta. In this study, we performed stability assessment of common reference-genes under Melatonin-supplementation and abiotic stress in leaves and seedlings of Catharanthus roseus using geNorm, NormFinder, BestKeeper, ΔCt and RefFinder algorithms. Nine candidate reference-genes were tested for stability in C. roseus (FBOX, CACS, TIP, RSP9, EXP, EXPR, SAND, F17M5, ACT) and our study inferred that while EXP and EXPR were the most-stable, F17M5 was the lowest-stable gene in the leaf-fed samples. Among seedlings of C. roseus, F17M5 and TIP were the most, while ACT was the least-stable gene. The suitability of selected stable reference-gene pairs was demonstrated by assessing the transcript levels of the Melatonin-biosynthesis gene SNAT under same conditions. Our study is the first to comprehensively analyze the stability of commonly-used reference-genes under Melatonin-induced conditions in C. roseus. |
