| An early response of plants to environmental signals or abiotic stress suggests that the phospholipid signaling pathway plays a pivotal role in these mechanisms. The phospholipid signaling cascade is one of the main systems of cellular transduction and is related to other signal transduction mechanisms. These other mechanisms include the generation of second messengers and their interactions with various proteins, such as ion channels. This phospholipid signaling cascade is activated by changes in the environment, such as phosphate starvation, water, metals, saline stres, and plant-pathogen interactions. One important factor that impacts agricultural crops is metal-induced stress. Because aluminum has been considered to be a major toxic factor for agriculture conducted in acidic soils, many researchers have focused on understanding the mechanisms of aluminum toxicity in plants. We have contributed the last fifteen years in this field by studying the effects of aluminum on phospholipid signaling in coffee, one of the Mexico's primary crops. We have focused our research on aluminum toxicity mechanisms in Coffea arabica suspension cells as a model for developing future contributions to the biotechnological transformation of coffee crops such that they can be made resistant to aluminum toxicity. We conclude that aluminum is able to not only generate a signal cascade in plants but also modulate other signal cascades generated by other types of stress in plants. The aim of this review is to discuss possible involvement of the phospholipid signaling pathway in the aluminum toxicity response of plant cells. | |
