Role of Petal-Specific Orcinol O-Methyltransferases in the Evolution of Rose Scent
(2006) Page(s) 21. ...petals of the cut flower variety ...Anna (PEKcougel)...have a long vase life of about 9 d due to their very resistant petals. Moreover, petals of this variety emit large amounts of DMT [3,5-dimethoxytoluene]...
(2006) Page(s) 20. ...[Lady Hillingdon] has been shown to produce large amounts of DMT [3,5-dimethyoxytoluene]...analysis indicated that OOMTs [Orcinol O-methyltransferase enzymes] were localized principally in the conical cells that constitute the upper epidermis of the petal and, to a lesse extent, in the supebidermal cell layer...
(2006) Page(s) 19. ...R. gallica and Damask rose possess a typical European scent, rich in monoterpenes and phenylethanol but devoid of phenolic methyl ethers...data suggests that the European species do not synthesize DMT [3,5-dimethoxytoluene] because they lack active OOMT [Orcinol O-methyltransferase] enzymes.
(2006) Page(s) 26. ...neither OOMT [Orcinol O-Methyltransferase enzyme] activity nor OOMT protein could be detected in the floral organs of [R. gallica and Damask rose]. The genomes of both R. gallica and Damask rose contain OOMT homologous sequences, but these genes are not expressed at detectable levels in either floral organs or leaves....
