Phosphoinositides are very versatile molecules with a plethora of functions such as cytokinesis, chemotaxis, cell survival, and cell death. Their functions depend on the proteins with which they interact. Thus, when interacting with phospholipases, phosphatases, or kinases, they can be precursors of second messengers in different signalling pathways. They could be second messengers themselves and interact directly with other proteins to modulate their functions trough changing its localization and activity or enhancing its synthesis rate. Because they are more abundant in animal cells and their importance in diseases such as cancer has taken priority, the study of the phosphoinositides in plants has not evolved to the same extent. Nevertheless, several studies have shown the significance of these lipids in plant cells viability and environmental response. This review focuses on phosphoinositides response to abiotic and biotic stress, showing their implication in plant survival during different stages of development.Significance of the studyThis review is focused on plant PIPs functions in stress, highlighting in the main differences between plant and mammal PIPs and the novel interactions that could be extrapolated to animal models to contribute in a better understanding of these pivotal molecules.
