Abstract:

To screen out the stable reference gene for Real-time quantitative PCR under rapid cold hardening conditions,ten candidate reference genes from the transcriptome sequencing of Lissorhoptrus oryzophilus Kuschel were selected.Real-time quantitative PCR was used to obtain the expression levels of the selected candidate reference genes in adults under different rapid cold hardening conditions.The expression stability of the selected candidate reference genes was analyzed by ΔCt method,geNorm,NormFinder and BestKeeper softwares.ΔCt predicted the most stable candidate reference gene was RPS18.It was revealed that RPS18 and G6DPH were the most stable reference genes based on the geNorm analysis,while G6DPH, RPL13 and α-tubulin were the most stable reference genes based on the NormFinder analysis and BestKeeper analysis,respectively.The stability of RPS18 gene was relatively high based on comprehensive analysis. It was found that the expression level of LoTPS gene increased under rapid cold acclimation when RPS18 was used as an internal reference gene, and it was higher in all the cold acclimation treatments than control. Therefore, RPS18 was relatively stable and could be used as an internal reference gene under different rapid cold acclimation conditions. Low temperature stress promoted the up-regulation of LoTPS gene under rapid cold acclimation, and the expression level increased with the prolongation of cold acclimation time.
