摘要
为筛选适合冬瓜稳定表达的内参基因,以黑皮冬瓜低温、高温、干旱胁迫处理不同时间的叶片和正常处理不同组织为试验材料,利用RT-qPCR技术,结合GeNorm、NormFinder和BestKeeper软件评价7个候选内参基因(28SrRNA、UBQ、RPⅡ、GAPDH、EF-1α、UBC21和TUA)稳定性。结果表明,7个候选内参基因在不同组织和不同胁迫处理下表达丰度及稳定性存在差异; EF-1α在低温胁迫处理下表达稳定性最好; UBQ和TUA在高温和干旱胁迫处理下表达稳定性最好; EF-1α在不同组织中表达稳定性最好。本研究结果为冬瓜内参基因的选择提供了一定的理论参考。
The present study aimed at selecting the stable reference genes to ensure the reliability and accuracy in gene expression analysis of wax gourd( Benincasa hispida Cogn.). By RT-PCR technology,combined with GeNorm,NormFinder,BestKeeper and ReFinder analysis,we investigated the expression stability of seven candidate reference genes( 28 SrRNA、UBQ、RP Ⅱ、GAPDH、EF-1α、UBC21、TUA). The results showed that,in different tissues and with different stress treatment,the expression abundance and stability of these seven reference genes were different. The expression stability of EF-1α was the best under low temperature stress.,UBQ and TUA showed the best expression stability under high temperature and drought stress,EF-1α was the best reference gene for different tissues. The results of this study can be used as a reference for the selection of internal reference genes in wax gourd.
