The ubiquitous volatile linalool is metabolized in plants to nonvolatile derivatives. We studied Nicotiana attenuata plants which naturally vary in (S)-(+)-linalool contents, and lines engineered to produce either (R)-(-)- or (S)-(+)-linalool. Only (S)-(+)-linalool production was associated with slower growth of a generalist herbivore, and a large fraction was present as nonvolatile derivatives. We found that variation in volatile linalool and its nonvolatile glycosides mapped to the same genetic locus which harbored the biosynthetic gene, NaLIS, but that free linalool varied more in environmental responses. This study reveals how (S)-(+)-linalool and conjugates differ in their regulation and possible functions in resistance.
