The effect of drought stress on the expression of key genes involved in the biosynthesis of phenylpropanoids and essential oil components in basil (Ocimum basilicum L.)

Drought stress may enhance the amount of methylchavicol content, in part, through increasing the expression of chavicol O-methyl transferase (CVOMT) gene, which is involved in the last biosynthetic step of estrogole (methylchavicol) formation.79
