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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
