Abstract
The Arabidopsis genome encodes similar to 20 different mitogen-activated pr otein kinases (MAPKs) that are likely to be involved in growth, development and responses to endogenous and environmental cues. Several plant MAPKs ar e activated by a variety of stress stimuli, including pathogen infection, w ounding, temperature, drought, salinity, osmolarity, UV irradiation, ozone and reactive oxygen species. Recent gain-of-function studies show that two tobacco MAPKs induce the expression of defense genes and cause cell death. By contrast, loss-of-function studies of other MAPK pathways revealed negat ive regulation of disease resistance. This'push-and-pull'regulation by diff erent MAPK pathways might provide a more precise control of plant defense r esponses.
