- This invention relates to an O-methyltransferase gene cloned from sorghum, the sorghum O-methyltransferase-3 gene, SbOMT3. Quantitative real-time RT-PCR and recombinant enzyme studies with putative O-methyltransferase sequences obtained from an EST data set from sorghum have led to the identification of the novel root hair-specific O-methyltransferase designated SbOMT3. Transgenic plants which express SbOMT3 can convert resveratrol into pterostilbene in planta. SbOMT3 is also involved in the biosynthesis of sorgoleone.
