However, Dr Pullen and his team present evidence that plant growth is actually «sink - limited,» meaning that genetic regulation and cell division rates have a much bigger role in controlling plant growth than previously thought: «We are proposing that plant growth is not physically limited by Net Primary Productivity (NPP) or the environment, but instead is limited genetically in response to these signals to ensure they do not become limiting.»

Scientists at the University of Bonn together with an international team discovered that nematodes produce a plant hormone to stimulate the growth of specific feeding cells in the roots.
