Abstract excerpt

Mitogen-activated protein kinases (MPKs) are regulated by diverse stresses with a reactive oxygen species (ROS) component. Here, we report the rapid and transient activation of MPK3, MPK4 and MPK6 upon oxygen deprivation as well as reoxygenation in seedlings of Arabidopsis thaliana. MPK activation peaked within 2 h of oxygen deprivation and again at a higher magnitude within 5 min of reoxygenation. MPK6 was the...
