摘要： Exogenous melatonin (MT) was found to be an interesting tool for enhancing the resistance of rice to Xanthomonasoryzaepv. oryzae (Xoo)-caused bacterial blight (BB). However, the accurate comparison of the expression levels across samples was a challenging task. In this work, the stability of 10 common used housekeeping genes under Xoo-infection and MT supplementation in rice was analyzed using quantitative real-time PCR (qRT-PCR), and algorithms geNorm, NormFinder and BestKeeper. Our results indicated that most reference genes remained stable in Xoo-infected rice plants, while a number of reference genes were affected by MT supplementation. Among all studied genes, the transcript levels of 18S(18S ribosomal RNA) and UBC (Ubiquitin-conjugating enzyme E2) remained unaltered by Xoo infection, while UBC and UBQ5(Ubiquitin 5) were the most stable genes when examining simultaneous Xoo-infection and MT supplementation, demonstrating that UBC is a suitable reference gene for qRT-PCR data normalization in rice under Xoo-infection and MT supplementation.
