The broad concept of “lipid signaling” refers to the pathways that generate or transform lipid molecules that transduce information downstream by interacting with relevant cell targets. The central enzymes involved in phosphoglycerolipid pathways are phospholipase C (PLC) and phospholipase D (PLD), both are capable of either direct or indirect production of phosphatidic acid (PA), a key signaling molecule that acts by binding to target proteins, thus altering their subcellular localization and their enzymatic activities. Phosphoglycerolipid signaling pathways are activated during plant exposure to both biotic and abiotic stresses. Furthermore, expression of genes encoding enzymes involved in these pathways is also altered under such conditions. Phytohormones also use phosphoglycerolipid signaling machinery for transduction of regulatory signals. Such functional connections are well documented for abscisic acid and salicylic acid, with increasing evidence for the involvement of other hormones. However, to date there have been few reports on the impact of stress on the interaction of phytohormones with the phosphoglycerolipid signaling machinery. In this review, we aim to shed light on the crosstalk between hormonal and phosophoglycerolipid signal transduction mechanisms
