TL;DR: Metabolic control analysis suggests that the presence of an additional phytoene synthase reduces the regulatory effect of this step over the carotenoid pathway, and the activities of other enzymes in the pathway (isopentenyl diphosphate isomerase, geranylgeranyl diph phosphate synthase, and incorporation of isopentanyl dphosphate into phy toene) were not significantly altered.

TL;DR: Transgenic lines containing a bacterial carotenoid gene (crtI) encoding the enzyme phy toene desaturase, which converts phytoene into lycopene are produced, finding the phenotype has been found to be stable and reproducible over at least four generations.

TL;DR: In tomato fruit with a residual 1% PG enzyme activity pectin depolymerisation was inhibited, indicating that PG is involved in pectIn degradation in vivo.

TL;DR: The extreme sensitivity of the olfactory organ has played an important role in the evolutionary development of mammals, allowing for the odor imprinting involved in olfaction recognition, and the fatigue factor must be considered in sensory work with aroma compounds.
