You can buy it, rent it, or develop it yourself. e economic pressures of competition and the impending deadline of new laws make that an imperative 8 . But with- out something, you will find it increasingly dif- ficult to stay in business, either because of prof- itability or reliability. PCB007 References 1. XACT PCB Ltd./InGeniusX. 2.

New technology has led to discoveries about the electrical signal- ling that causes the trap to snap shut. Bioelectronic technology enables advanced research into how plants react to their surroundings, and to stress. Plants have electrical signals that are generated in response to touch and stress factors, such as wounds caused by herbivores and attacks on their roots. As opposed to animals, who can move out of the way, plants must cope with stress factors where they grow. "There is currently a great need for developing plants that are more stress resistant, for us to be able to grow food and have healthy forests also in the future. That's why it's important that we under- stand how plants respond to stress, and I think that this new technology may contribute in this area of research." says Eleni Stavrinidou, associate profes- sor in the Department of Science and Technology at Linköping University, LiU and leader of the Elec- tronic Plants group. It turns out that in some plants electrical signals are correlated with rapid movements. The carnivo- rous plant Venus Flytrap (Dionaea mus- cipula) is used by researchers as a model system for fast electrical signalling in plants. New measuring technology lets the researchers discover new information. One of the most important aspects of this study is that we show that bioelectronic technologies, which are extensively used in biomedical research, can be applied to plant physiology research as well, there- fore opening possibilities for new discov- eries" says Eleni Stavrinidou.
