Plant Root Interactions
The modular structure of plant root systems enables a high degree of flexibility (or plasticity) in responding to prevailing conditions in the soil, including resource distribution. However, more recently, it has been suggested that root-root interactions are more sophisticated than simply being driven by resource availability alone. Some evidence suggests that plant roots may be able to recognise their own roots from those of other plants even when the other plant is a genetically identical individual, while other studies suggest plants may be able to identify related individuals (kin) from non-related individuals and modify their competitive interactions as a result. The results of these studies together with their limitations will be reviewed here.
