Along with five European academic laboratories, researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to Ghent University are accelerating the study of the model plant Arabidopsis thaliana.
Taking advantage of the new RNAi technology, they are able to study the function of genes with the aid of specially designed fragments that turn off the corresponding genes. The scientists are building a collection of such fragments in Arabidopsis. Their ultimate goal is to contribute to the elucidation of the functions of all the genes in this model organism. Furthermore, this collection will also benefit research into other organisms, namely humans and animals.
Arabidopsis thaliana or the mouse-ear cress (a member of the mustard family) is a weed that is cultivated in numerous labs. Indeed, due to its genetic simplicity − it contains ‘only’ 29,000 genes − it is the most widely studied plant. The DNA sequence of Arabidopsis has been known for several years, and scientists worldwide are now concentrating on the search for the genes and the function of the proteins involved. Not only will this lead to new insights into the functioning of plant cells, which is important for agriculture and nutrition, but it will also shed light on the role of animal and human genes. More and more, scientists are discovering that biological processes in animals and humans are comparable to processes in plants.
