additional information	during extended dark, sulfite oxidase activity is enhanced in tomato wild-type leaves, while the other sulfite network components are down-regulated. Exogenous sulfite application induces up-regulation of the sulfite scavenger activities in dark-stressed or unstressed wild-type plants, while expression of the sulfite producer, adenosine 5'-phosphosulfate reductase, is down-regulated	Solanum lycopersicum

General Information

General Information	Comment	Organism
physiological function	during extended dark, sulfite oxidase activity is enhanced in tomato wild-type leaves, while the other sulfite network components are down-regulated. RNA interference treated plants accumulate sulfite, resulting in leaf damage and mortality. Exogenous sulfite application induces up-regulation of the sulfite scavenger activities in dark-stressed or unstressed wild-type plants, while expression of the sulfite producer, adenosine 5'-phosphosulfate reductase, is down-regulated. Unstressed or dark-stressed wild-type plants are resistant to sulfite applications, but enzyme RNA interference plants show sensitivity and overaccumulation of sulfite. Under extended dark stress, SO activity is necessary to cope with rising endogenous sulfite levels. Under nonstressed conditions, the sulfite network can control sulfite levels in the absence of enzyme activity	Solanum lycopersicum
