Specifically, genes related to rosmarinic acid biosynthesis were cloned and characterized for <i>O</i>. <i>basilicum</i>. We obtained partial cDNAs of tyrosine aminotransferase (TAT) and 4-hydroxyphenylpyruvate reductase (HPPR), which were of 323 bp and 616 bp in size, respectively. The transcription levels of most genes related to rosmarinic acid synthesis were higher in green basil compared to purple basil, except for <i>ObPAL</i> and <i>Ob4CL</i> in the root. The highest expression was obtained in the leaves of green basil for all genes and the roots of purple basil for all genes,Saudi journal of biological sciences469-472https://www.ebi.ac.uk/biostudies/studies/S-EPMC6408686biostudies-literatureMolecular cloning and characterization of rosmarinic acid biosynthetic genes and rosmarinic acid accumulation in <i>Ocimum basilicum</i> L.PMC6408686Li XKim JKKwon DYPark SUfalseMolecular cloning and characterization of rosmarinic acid biosynthetic genes and rosmarinic acid accumulation in <i>Ocimum basilicum</i> L.We have aimed to investigate the expression of genes related to rosmarinic acid (RA) synthesis and rosmarinic acid content in 2 <i>Ocimum basilicum</i> cultivars, green (cinnamon) and purple (red rubin) basil.
