Lilium; alkyl (aryl) transferases; beta-ocimene; biosynthesis; calyx; catalytic activity; circadian rhythm; corolla; cut flowers; gas chromatography-mass spectrometry; genes; herbaceous plants; messenger RNA; mitochondria; nerolidol; odors; ornamental plants; plastids; quantitative polymerase chain reaction; volatile compounds
Abstract:
... MAIN CONCLUSION: Floral scent formation in Lilium ‘Siberia’ is mainly due to monoterpene presence in the floral profile. LoTPS1 and LoTPS3 are responsible for the formation of (±)-linalool and β-ocimene in Lilium ‘Siberia’. Lilium ‘Siberia’ is a perennial herbaceous plant belonging to Liliaceae family, cultivated both as a cut flower and garden plant. The snowy white flower emits a pleasant aroma ...

Abstract:
... MAIN CONCLUSION: Five Vitis vinifera sesquiterpene synthases were characterized, two was previously uncharacterized, one being a caryophyllene/cubebene synthase and the other a cadinene synthase. Residue differences with other Vitis sesquiterpene synthases are described. The biochemical composition of grape berries at harvest can have a profound effect on the varietal character of the wine produce ...
