The (seco)iridoids and their derivatives, the monoterpenoid indole alkaloids (MIAs), form two large families of plant-derived bioactive compounds with a wide spectrum high-value pharmacological insect-repellent activities. Vinblastine vincristine, MIAs used as anticancer drugs, are produced by Catharanthus roseus in extremely low levels, leading to high market prices poor availability. Their biotechnological production is hampered fragmentary knowledge biosynthesis. Here we report discovery...
Wine aroma strongly influences wine quality, yet its composition and evolution during the winemaking process are poorly understood. Volatile compounds that constitute traditionally divided into three classes according to their origin: grape, fermentation maturation aroma. We challenge this view with meta-analysis review of grape volatiles precursors from 82 profiling experiments. compiled a list 141 common quantitatively compared 43 them. Our work offers insight complex relationships between...
Monoterpenes are important constituents of the aromas food and beverages, including wine. Among monoterpenes in wines, wine lactone has most potent odor. It was proposed to form via acid-catalyzed cyclization (E)-8-carboxylinalool during maturation. only reaches very low concentrations but its extremely odor detection threshold makes it an aroma compound. Using LC-MS/MS, we show here that content wines correlates with their estimate kinetic constant for slow formation from...
Cytochromes P450 are enzymes that participate in a wide range of functions plants, from hormonal signaling and biosynthesis structural polymers, to defense or communication with other organisms. They represent one the largest gene/protein families plant kingdom. The manual annotation cytochrome genes genome Vitis vinifera PN40024 revealed 579 sequences, including 279 complete genes. Most sequences grapevine organized physical clusters, resulting tandem segmental duplications. Although most...
