Plants, being sessile, are simultaneously exposed to several biotic and abiotic stresses. The sensitivity of stress signals in plants implicates a varied spectrum of signal transduction pathways that interact to induce tolerance against adverse environmental conditions. This functional overlapping among several stress signaling cascades also leads to the expression of genes that regulate biosynthesis or action of other hormones. Phytohormonal signals, triggered by both developmental and environmental responses, play a vital role to improve stress tolerance in plants. Nitric oxide (NO) is one of the foremost players in plant signaling networks. Emerging indication supports that NO interplays with signaling pathways of auxins, gibberellins, abscisic acid (ABA), ethylene, jasmonic acid (JA), brassinosteroids (BR), and other plant hormones to control metabolism, growth, and development in plants. This chapter emphases on the existing state of knowledge of cross talk between signaling pathways of NO and phytohormones in plants exposed to several abiotic stresses.
