Journal ArticleDOI
Nitric oxide plays a central role in determining lateral root development in tomato.
TL;DR: It is reported that NO promotes lateral root (LR) development, an auxin-dependent process, and a novel role for NO in the regulation of LR development is suggested, probably operating in the auxin signaling transduction pathway.
Journal ArticleDOI
Characterization of a Nitric Oxide Synthase from the Plant Kingdom: NO Generation from the Green Alga Ostreococcus tauri Is Light Irradiance and Growth Phase Dependent
Noelia Foresi,Natalia Correa-Aragunde,Gustavo Parisi,Gonzalo Caló,Graciela L. Salerno,Lorenzo Lamattina +5 more
TL;DR: This study characterizes a nitric oxide synthase (NOS) from Ostreococcus tauri, a marine green alga, and found the amino acid sequence of O. tauri NOS was found to be 45% similar to that of human NOS.
Journal ArticleDOI
Nitric oxide modulates the expression of cell cycle regulatory genes during lateral root formation in tomato
TL;DR: It is shown that NO modulates the expression of cell cycle regulatory genes in tomato pericycle cells and leads, in turn, to induced LR formation, indicating that NO is required for LR primordia formation and not for LR emergence.
Journal ArticleDOI
Arginase-Negative Mutants of Arabidopsis Exhibit Increased Nitric Oxide Signaling in Root Development
Teresita Flores,Christopher D. Todd,Alejandro Tovar-Méndez,Preetinder K. Dhanoa,Natalia Correa-Aragunde,Mary Elizabeth Hoyos,Disa M. Brownfield,Robert T. Mullen,Lorenzo Lamattina,Joseph C. Polacco +9 more
TL;DR: It is proposed that Arg, or an Arg derivative, is a potential NO source and that reduced arginase activity in the mutants results in greater conversion of Arg to NO, thereby potentiating auxin action in roots.
Journal ArticleDOI
Climate Change and the Impact of Greenhouse Gasses: CO2 and NO, Friends and Foes of Plant Oxidative Stress.
TL;DR: In conclusion, NO plays a central role in the tolerance of plants to climate change, and regulates GSH concentration in several ways.
