Number of genes involved in specialized metabolite synthesis in Tulsi genome. a. There are four classes of metabolites present in Ocimum genome viz., sesquiterpenes (52 %), flavonoids (19 %), terpenes (18 %) and phenylpropanoids (11 %). Number in the bracket is percentage of sepecialized metabolites present in the genome. 458 genes were identified as coding for enzymes involved in synthesis of specialized metabolites. b. Specialized metabolic pathways of disease relevance proposed in Ocimum tenuiflorum. Major classes of diseases investigated are indicated in different colors: anticancer , anticancer-antioxidant , antifungal , antiseptic , anti-infective , antioxidant , and anti-inflammatory . The enzymes have been labelled with 5–7 letters for convenience. The numbers after the’_’ in the enzyme label represent the number of putative hits found for the given enzyme in the genomic assembly of O. tenuiflorum. The metabolites involved in the disease relevance and the enzymes involved in the synthesis of these metabolites are as follows: APIGENIN (Flavone-synthaseI-FSYN1, Naringenin-NADPH-oxygen-oxidoreductase-NNOOX), LUTEOLIN (Flavone-synthaseI-FSYN1, Naringenin-NADPH-oxygen-oxidoreductase-NNOOX, Flavone-3-monooxygenase-F3MON), TAXOL (Taxadiene-synthase-TSYN, Taxadiene-5-alpha-hydroxylase-T5AHYD, Taxadien-5-alpha-ol-O-acetyltransferase-T5AOOA, Taxane-10-beta-hydroxylase-T10BHYD, Taxoid-14-beta-hydroxylase-T14BHYD, 2-alpha-hydroxytaxane-2-O-benzoyltransferase-2AH2OB, 10-deacetylbaccatin-III-10-O-acetyltransferase-10D10OA, 3-N-debenzoyl-2-deoxytaxol-N-benzoyltransferase-3ND2DNB, URSOLIC ACID (ursolic-aldehyde-28-monooxygenase-UA28M, Alpha-amyrin-synthase-AASYN), OLEANOLIC ACID (Beta-amyrin-synthase-BASYN, oleanolic-aldehyde-28-monooxygenase-OA28M), SITOSTEROL (24C-methyltransferase-24CMET), ROSMARINIC ACID I (4-coumaroyl-4-hydroxyphenyllactate-3-hydroxylase-4C4H3H, Tyrosine-transaminase-TTRAN), ROMARINIC ACID II (Hydroxyphenylpyruvate-reductase-HPPRE, Tyrosine-3-monooxygenase-TTRAN), METHYL CAHVICOL (Eugenol-o-methyltransferase-EOMET), EUGENOL (Alcohol-o-acetyltransferase-AOACE, Eugenol-synthase-ESYN, Isoeugenol-synthase-ISYN), LINALOOL (Farnesyl-pyrophosphate-synthase-FPSYN, R-linool-synthase-RLSYN, S-linool-synthase-SLSYN), CARYOPHYLENE (Alpha-humulene-synthase-AHSYN, Beta-caryophyllene-synthase-BCSYN), SELINENE (Alpha-selinene-synthase-ASSYN, Beta-selinene-synthase-BSSYN), CITRAL (Geraniol-synthase-GSYN, Geraniol-dehdrogenase-GDHYD)
