Abstract
The mitogen activated protein kinase cascade is a highly conserved signal pathway in plants. The exogenous chemicals, like hormones, can trigger a series of signalling cascades, including MAPK pathway, to modulate the plant physiology. Upon activation, some MAPKs are phosphorylated. It is important to develop methods that can detect changes in the phosphorylation status of MAPKs in plants when they come in contact with external chemicals. This method describes the exogenous treatment of Arabidopsis protoplasts with Kinetin and subsequent detection of the activated MAPKs. This method is useful for studying the effect of exogenously applied chemical compounds on the MAPK signaling cascade in Arabidopsis.
