Abstract

The production of the redox-active signaling molecule, NO, has long been associated with interactions between microbes and their host plants. Emerging evidence now suggests that specific NO signatures and cognate patterns of PHYTOGLOBIN1 (PHYTOGB1) expression, a key regulator of cellular NO homeostasis, may help determine either symbiosis or pathogenicity.

Keywords: S-nitrosoglutathione reductase; mycorrhiza; nitric oxide; phytoglobin; symbiosis.
