Distant Relatives: TOR Protein Regulates Cell Growth in Plants and Animals

Two such different organisms as plants and humans developed from a common precursor cell. Traces of this over one-billion-year kinship remain anchored in the genetic material of both organisms. An international team of plant researchers led by Dr Markus Wirtz and Prof. Dr Rüdiger Hell of Heidelberg University has looked more closely into one such trace – the TOR protein. In human and animal cells, TOR acts as a signal generator that controls both survival and cell growth. The Heidelberg researchers have now discovered how this protein also functions as a growth regulator in plants. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
