Just one cellular pathway produces the raw ingredients plants use to make thousands of compounds, from molecules with anticancer properties to the active ingredient in catnip, according to a team of researchers at Purdue University and the Max Planck Institute for Chemical Ecology.
This finding challenges long-held assumptions about how plants produce these commercially important products. The research also could have important implications for researchers trying to harness plant pathways to produce essential oils, often used as flavor additives in food and medicine or as fragrance in body-care products, said Natalia Dudareva, professor of horticulture and lead researcher of the study. "Our research has applications in the future metabolic engineering of essential oil production," Dudareva said. "The yield of these compounds depends on the amount of materials available in the cell, and knowing where these compounds come from and which pathway produces them is the place to start."
Dudareva and her colleagues report in the current issue (Tuesday, Jan. 18) of Proceedings of the National Academy of Science that the molecular precursors to a group of compounds called terpenoids - the largest and most diverse family of natural products - come from a single plant pathway, located inside the same part of a cell where photosynthesis occurs.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
