Figure 2From: The next frontier of systems biology: higher-order and interspecies interactionsHigher-order interactions. As the left-hand side of the diagram shows, multiple perturbations within a single species (for example, double mutants subjected to multiple conditions or stresses) are now possible and are delving into previously unexplored interactome space. The right-hand side of the diagram symbolizes how in the future, simultaneous studies such as these on several different species interacting with each other will be possible.Back to article page
