Plants use different signalling pathways to acclimate to changing environmental conditions. Fast changes in the concentration of free @entity141 ions - so called @entity141 signals - are among the first responses to many stress situations. These signals are decoded by different types of @entity460 -dependent protein kinases, which - together with mitogen-activated protein kinases (MAPK) - present two major pathways that are widely used to adapt the cellular metabolism to a changing environment. @entity141 -dependent protein kinase (CDPK) and MAPK pathways are known to be involved in signalling of abiotic and biotic stress in animal, @entity375 and plant cells. In many cases both pathways are activated in response to the same stimuli leading to the question of a potential cross-talk between those pathways. Cross-talk between @entity141 -dependent and MAPK signalling pathways has been elaborately studied in animal cells, but it has hardly been investigated in plants. Early studies of CDPKs involved in the biotic stress response in @entity286 indicated a cross-talk of CDPK and MAPK activities, whereas a recent study in @entity958 revealed that CDPKs and MAPKs act differentially in innate immune signalling and showed no direct cross-talk between CDPK and MAPK activities. Similar results were also reported for CDPK and MAPK activities in the salt stress response in @entity958 . Different modes of action are furthermore supported by the different subcellular localization of the involved kinases. In this review, we discuss recent findings on CDPK and MAPK signalling with respect to potential cross-talk and the subcellular localization of the involved components.
