A team of scientists at the Hebrew University of Jerusalem has found a way to genetically enhance the scent of flowers and implant a scent in those that don't have one.
Smell plays an important role in our lives: It influences the way in which we choose fruit and vegetables, perfume, and even a partner. And yet, smell is not just what we smell with our noses, it's also what we taste, explains Prof. Alexander Vainstein, who is heading the team at the Robert H. Smith Faculty of Agriculture, Food and Environment. "Aroma is of major importance for defining the taste of food."
Scent in flowers and plants is used to attract pollinating insects like bees and beetles that pass on the pollen and help in the reproduction and creation of fruit. The intensity of the scent that the flower emanates is influenced by the time of day, depending on weather, age of the flower and the species.
In research that was published recently in the Plant Biotechnology Journal, Prof. Vainstein and his research assistant Michal Moyal Ben-Tzvi succeeded, together with other researchers, to find a way of enhancing the scent of a flower by ten-fold and cause it to emit a scent during day and night - irrespective of the natural rhythm of scent production.
The development, which has been patented by Yissum, the Hebrew University's technology transfer company, is intended to be applied to other agricultural produce.
Utilizing natural components will increase and change not only the smell of fruit and vegetables, but also influence the commercial appeal of a wide array of produce.
The flower industry will also be interested in this development, explains Prof. Vainstein. "Many flowers lost their scent over many years of breeding. Recent developments will help to create flowers with increased scent as well as producing new scent components in the flowers."
Over a third of participants in Flowers and Plants Association surveys stated that scent influenced their choice of flower purchase. Floral scents are also one of the most popular smells and the perfume industry expends a great deal of effort trying to reproduce the authentic fragrance of fresh flowers.
Prof. Vainstein's lab is the only one in the world that researches both the scent and color of flowers. His greenhouse at the Hebrew University's Rehovot campus is full of genetically engineered flowers whose architecture, color and scent the researchers are trying to alter.
Israel is the Middle East's flower-producing superpower. Its flower, plant and propagation material exports bring upwards of $200 million into the economy annually. Israel is third only to the Netherlands and Kenya in supplying the EU with flowers. Each year, 1.5 billion stems are exported - twice as many as 10 years ago.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
