草地早熟禾熒光定量PCR分析中內(nèi)參基因的篩選
[Abstract]:In order to screen the optimal internal reference gene in the real-time fluorescence quantitative analysis of Kentucky bluegrass, six traditional internal reference genes, ACT,GAPDH,UBQ,EF-1 偽 ~ (18 s) rRNA and 尾 -tublin, were detected by real-time fluorescence quantitative PCR technique in different tissues and organs and different developmental stages of leaves of Kentucky bluegrass. The difference of mRNA expression under abiotic stress and different hormone induction. The expression stability of 6 candidate internal reference genes was evaluated by geNorm,NormFinder and BestKeeper software. The results showed that in different tissues, leaves at different developmental stages, hormone induction and abiotic stress, There were differences in the expression stability of candidate endogenous reference genes. The expression of EF-1 偽 was the most stable in different tissues and organs of Kentucky bluegrass. The expression of EF-1 偽 was the most stable under abiotic stress; 尾 -tublinin was the first choice under different hormones; and the ACT expression was the most stable in different development stages of leaves. To sum up, screening suitable internal reference genes under different conditions can not only improve the accuracy of gene expression analysis of Kentucky bluegrass, but also provide a theoretical reference for the development of other internal reference genes in POA plants.
