Molecular basis of phosphoinositide-specific phospholipase C signaling pathways in plant cells

O. M. Iakovenko, S. V. Kretynin, V. S. Kravets

In plants external stimulus can be perceived and amplified in the cells by functional signaling cascades. Phosphoinositide-specific phospholipase C is an enzyme shown to initiate and provide key events in the cellular responses to extracellular signals. Both substrate and products of phospholipase C are involved in the regulation of numerous processes in plant cells. In this review, we focused on molecular basis of the phosphoinositide-specific phospholipase C signaling pathways. The data analyzed will help to elucidate the mechanisms responsible for plant’s ability to respond to a variety of biotic and abiotic stress signals.

Keywords: phosphoinositide-specific phospholipase C, signal transduction.
