Abstract:

In this study, eight reference genes (EF1α, MADH, ACT2, GAPDH, TUB, ACT54, CYP and EF1β) from the transcriptome database, were selected and analyzed in Rema No.1 including Phytophthora nicotianae Breda, MeJA, SA and ABA treatments. Statistical tools, including GeNorm, NormFinder and BestKeeper, were utilized to assess the suitability of reference genes based on the stability rankings for different species. The stability of the eight reference genes was significantly different under different treatments in Rema No.1. For Phytophthora nicotianae Breda and MeJA stresses, EF1α was identified as the most stable gene and EF1β was identified as the least stable gene. For SA stress, EF1α was identified as the most stable gene, and ACT2 was identified as the least stable gene. For ABA stress, GAPDH was identified as the most stable gene, and ACT54 was identified as the least stable gene. The results would provide reliable and optional available reference genes in gene expression analysis of sisal.

Key words: sisal, qRT-PCR, reference gene
