After a brief introduction into the signals (growth regulators, fungal elicitors, light and gravity) and their receptors in plant signal transduction, secondary messengers including cytosolic Ca2+ and platelet-activating-factor which stimulates plant H+-ATPase in vitro are considered. A model for plant growth regulator action at the molecular level is proposed. Auxin activation of phospholipase A2 and the lysophospholipid-activated protein kinase are combined to produce a model signal transduction chain.
