Abiotic stress signalling pathways: specificity and cross-talk.

Plants exhibit a variety of responses to abiotic stresses that enable them to tolerate and survive adverse conditions. As we learn more about the signalling pathways leading to these responses, it is becoming clear that they constitute a network that is interconnected at many levels. In this article, we discuss the 'cross-talk' between different signalling pathways and question whether there are any truly specific abiotic stress signalling responses.
