Nitric Oxide (NO) is an important redox based regulator of cell physiology involved in many signalling processes in plants. The precise mechanism of how NO interacts with or activates different targets is still poorly understood. The polar lipid phosphatidic acid (PA) is another molecule involved in plant signalling. NO and PA have been independently regarded as general, multifunctional stress signalling molecules in plants. Since they share common effectors we hypothesized NO and PA participate in the same signalling pathway. Results obtained in our laboratory revealed that NO can induce PA formation during i) plant-defense responses; ii) stomatal closure and iii) adventitious root formation.
