The Oxford English Dictionary defines crosstalk as ‘unwanted transfer of signals between communication channels’. How does this definition relate to the way in which we view the organization and function of signalling pathways? Recent advances in the field of plant signalling have challenged the traditional view of a signalling transduction cascade as isolated linear pathways. Instead the picture emerging of the mechanisms by which plants transduce environmental signals is of the interaction between transduction chains. The manner in which these interactions occur (and indeed whether the transfer of these signals is ‘unwanted’ or beneficial) is currently the topic of intense research.
