Abstract

Cell signaling integrates independent stimuli using connections between biochemical pathways. The sensory apparatus can be represented as a network, and the connections between pathways are termed crosstalk. Here, we describe several examples of crosstalk in plant biology. To formalize the network of signal transduction we evaluated the relevance of mechanistic models used in artificial intelligence. Although the perceptron model of neural networking provides a good description of the process, we suggest that Boolean networks should be used as a starting framework. The Boolean network model allows genetic data to be integrated into the logical network of connections deduced from DNA microarray data.
