Nitric oxide (NO) is a chemical messenger that is actively operating in the plant kingdom. In recent years, NO has been involved in many and diverse growth, developmental and physiological processes in plants. It has been shown that NO takes part of different hormone signaling pathways and also acts in concert with well characterized second messengers. In this chapter, we discuss findings that contribute to understand the NO role/s during root organogenesis and stomatal movement, focusing on the interrelations between NO and the phytohormones auxin and abscisic acid (ABA). We emphasize in the requirement of calcium as an essential intermediate present in the NO-mediated responses. Finally, novel data concerning the cross talk between NO and phosphatidic acid (PA) signaling pathways in responses to (a)biotic stresses are presented and discussed.
