N⁶-methyladenosine RNA modification regulates light intensity-dependent terpenoid biosynthesis in Schizonepeta tenuifolia.

ABSTRACT: Schizonepeta tenuifolia Briq. (S. tenuifolia) is a traditional Chinese medicinal plant widely used to treat colds, fever and respiratory diseases. Volatile oils including the monoterpenoids limonene, pulegone and menthone are major constituents of S. tenuifolia that determine its medicinal value and consumer popularity. A better understanding of the molecular regulatory mechanisms underlying terpenoid accumulation is needed to improve the quality and market value of S. tenuifolia. Here, we demonstrate that limonene and pulegone accumulate in S. tenuifolia under high-light conditions, whereas menthone accumulates in the dark. Transcriptome and proteome analyses revealed that light up-regulated both the transcriptional and protein levels of limonene synthase (LS), whereas darkness elevated p
