Dietary carcinogens and anticarcinogens Oxygen radicals and degenerative diseases
TL;DR: Dietary intake of natural antioxidants could be an important aspect of the body's defense mechanism against these agents of cancer and other age-related diseases.

Physiology and Molecular Biology of Phenylpropanoid Metabolism
Klaus Hahlbrock,Dierk Scheel +1 more
TL;DR: Studies of the molecular genetics, mechanisms of activation and functional connections between general phenylpropanoid metabolism and certain branch pathways in parsley, bean, potato plants and cell cultures are studied.
Journal ArticleDOI
Production of plant secondary metabolites: a historical perspective
TL;DR: Plant cell culture technologies were introduced at the end of the 1960s as a possible tool for both studying and producing plant secondary metabolites, and it is now possible to manipulate the pathways that lead to secondary plant compounds.

Existing and potential applications of ultraviolet light in the food industry - a critical review
TL;DR: The penetration of UVA into water is better than that of UVC, and its bacteriocidal action in the presence of photosensitisers can be rapid, however, pure furocoumarins are expensive and their addition to foodstuffs might be questioned on safety grounds.

Biosynthesis of coumarins in plants: a major pathway still to be unravelled for cytochrome P450 enzymes
Frédéric Bourgaud,Alain Hehn,Romain Larbat,S. Doerper,Eric Gontier,Sandra Kellner,Ulrich Matern +6 more
TL;DR: This review highlights the major steps of the coumarin pathway with emphasis on the cytochrome P450 enzymes involved, including Ortho-hydroxylation of hydroxycinnamic acids, and the outcomes of novel strategies developed to uncover cou marin-committed CYPs.

Patterns of Furanocoumarin Distribution and Insect Herbivory in the Umbelliferae: Plant Chemistry and Community Structure
TL;DR: Chemical survey of 12 species of Umbelliferae revealed that species possessing furanocoumarins are most frequently found in open habitats: either swamps or thickets or disturbed areas such as roadsides or old fields, and Cluster analysis of the insects on these umbellifers demonstrates that insect herbivores distribute themselves according to host furanOCoumarin chemistry.

Ultraviolet Light-induced Formation of Pisatin and Phenylalanine Ammonia Lyase.
TL;DR: The induced synthesis of pisatin and PAL by ultraviolet light is described and it is suggested that ultraviolet light which can dimerize thymidine bases and cause lesions in DNA should also influence this response.

Photosensitization of bacteria by furocoumarins and related compounds.
TL;DR: Photosensitization of bacteria by psoralen and related compounds is described in this communication and results in increased pigmentation and photosensitizing action of endogenous chlorophyll.

Linear furocoumarins (psoralens) from the seed of Texas Ammi majus L. (Bishop's Weed).
TL;DR: Most of the major A. majus psoralens are potent photosensitizers, based on bioassays against chick skin, and the presence of these compounds in the seed and other parts of A. majesty almost certainly accounts for the high photosensitizing activity of this plant toward cattle and sheep.
