“…The expression levels of the following genes were monitored with specific primer set of cinnamate 4-hydroxylase gene C4H (Accession No. HM990150) , 4-coumarate CoA ligase 4CL (KC576841) , cinnamoyl-CoA reductase CCR (in this study) , cinnamyl alcohol dehydrogenase CAD (AY879285) , coniferyl alcohol acetyl transferase CAAT1 (MN031888) , eugenol (and chavicol) synthase EGS1 (DQ372812) , eugenol O -methyltransferase EOMT (AF435008, XLOC_068107 and XLOC_068808) , 1,8-cineole synthase CIN (in this study) , S -linalool synthase LIS (in this study) , OPR3 ( O. basilicum Chr: scaffold10, 7,268,155–7,270,534) , and β-tubulin (MH620961.1) genes in O. basilicum (Supplementary Table 2 ) 15 – 18 . Relative expression ratios for each target gene were calculated using β-tubulin gene expression in the same experimental samples.…”
