An interdisciplinary team of researchers from Warwick's School of Life Sciences, Centre for Systems Biology and the Department of Computer Science have discovered hundreds of regions in plant DNA that have been preserved across different species through 100 million years of evolution. These regions are not part of any genes, but may be responsible for turning individual genes "on" and "off". The discovery will help biologists to understand better the genetics of plants, leading to potential applications in agriculture and food security. This research has been made possible by a computational analysis of the DNA in several plant species, based on algorithms developed by a DCS academic Dr Alexander Tiskin and his former PhD student Dr Peter Krusche (now working at Warwick's Centre for Systems Biology). The research was published in the journal Plant Cell.
