New technology eliminates plant toxins

06.08.2012
Plants produce toxins to defend themselves against potential enemies, from herbivorous pests to diseases.

Oilseed rape plants produce glucosinolates to serve this purpose. However, due to the content of glucosinolates, farmers can only use limited quantities of the protein-rich rapeseed for pig and chicken feed.

Now, a team of researchers from the University of Copenhagen has developed a method to hinder unwanted toxins from entering the edible parts of the plant. The breakthrough was published today in the prominent scientific journal Nature.

"We have developed an entirely new technology that we call 'transport engineering'. It can be used to eliminate unwanted substances from the edible parts of crops," says Professor Barbara Ann Halkier, head of the Center of Excellence for Dynamic Molecular Interactions (DynaMo) at the University of Copenhagen's Faculty of Science.

The potential for toxin-free oilseed rape as a feed crop

The oilseed rape plant is but one example of a crop whose use will be greatly enhanced thanks to the new technology. Unlike the healthy glucosinolates found in broccoli, oilseed rape additionally produces a glucosinolate that is harmful to most animals when consumed in larger amounts.

This means that protein-rich rapeseed cake produced using the byproduct of rapeseeds pressed for oil, can only be used in limited quantities for pig and chicken feed. Due to this, Northern Europe continues to import large amounts of soy cake for animal feed.

Two transport proteins found
The breakthrough increases the potential of oilseed rape as a commercial animal feed:

"We managed to find two proteins that transport glucosinolates into the seeds of the thale cress plant, a close relative of the oilseed rape. When we subsequently produced thale cress without these two proteins, the remarkable result was that their seeds were completely free of glucosinolates and thus suitable for feed," emphasises Barbara Ann Halkier.

Worldwide, oilseed rape is the third most widely grown oilseed-producing crop. 'Transport engineering', the new technology platform, is so promising that one of the world's largest companies involved in plant biotechnology – Bayer CropScience – is now negotiating with the University of Copenhagen's Tech Transfer Unit to collaborate with the research group so as to deploy the new technology and produce an oilseed rape plant with glucosinolate-free seeds. According to Bayer CropScience project leader Peter Denolf such seeds will significantly enhance the use of oilseed rape meal as animal feed and bring along a more sustainable oilseed rape processing procedure.

The research results are the fruit of 16 years of basic research, an excellent example of how basic research can result in new discoveries of direct use for society.

The DOI for the scientific paper published in Nature will be 10.1038/nature11285.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
