General Information

General Information	Comment	Organism
physiological function	when expressed in Escherichia coli, enzyme extends the prenyl chain length of the endogenous ubiquinone to nine isoprene units respectively. In planta, constitutive overexpression elevates the plastoquinone content of immature tobacco leaves. Virus-induced gene silencing shows that the enzyme is necessary for normal chloroplast structure and function. Plants silenced for SPS are photobleached and accumulate phytoene	Solanum lycopersicum
