Expression of phytoglobin affects nitric oxide metabolism and energy state of barley plants exposed to anoxia
Abstract Class 1 plant hemoglobins (phytoglobins) are upregulated during low-oxygen stress and participate in metabolism and cell signaling via modulation of the levels of nitric oxide (NO). We studied the effects of overexpression and knockdown ...

Shedding light on NO homeostasis: Light as a key regulator of glutathione and nitric oxide metabolisms during seedling deetiolation
Abstract Despite the significant impacts of light on nitric oxide (NO) levels in plants, the mechanism underlying the influence of this environmental factor on NO metabolism remains poorly understood. A critical mechanism controlling NO levels in ...

Blood pressure–lowering effect of orally ingested nitrite is abolished by a proton pump inhibitor
Abstract Inorganic nitrate and nitrite from dietary and endogenous sources are metabolized to NO and other bioactive nitrogen oxides that affect blood pressure. The mechanisms for nitrite bioactivation are unclear, but recent studies in rodents ...
