co-expression network of the Arabidopsis thaliana solanesyl-diphosphate synthase family
malfunction

in contrast to other plastochromanol-8 biosynthetic mutants, neither the single atsps knock-outs nor the atsps1 atsps2 double knock-out display any defects in tocopherols accumulation or germination
malfunction
knockout of genes AtSPS1 and AtSPS2 causes a reduction in plastoquinone-9 content in leaves, and the leaves exhibit light suppression of photosynthetic system II under high-intensity light
malfunction
leaves of the atsps2 knock-out are devoid of plastochromanol-8 and display severe losses of both non-photoactive and photoactive plastoquinone-9, resulting in near complete photoinhibition at high light intensity. The photoinhibition is paralleled by significant damage to photosystem II but not to photosystem I. In contrast to other plastochromanol-8 biosynthetic mutants, neither the single atsps knock-outs nor the atsps1 atsps2 double knock-out display any defects in tocopherols accumulation or germination
malfunction
-
plants silenced for SlSPS are photobleached and accumulate phytoene
malfunction
RNAi-mediated depletion of TbSPPS leads to severe growth inhibition. Ablation of TbSPPS by RNAi will decrease the function of the glycerol-3-phosphate shuttle, which is cured by application of glycerol. The viability of the BSF cells is compromised upon RNAi induction, phenotype overview. Addition of ubiquinone to the medium alleviates the effect of RNAi-mediated depletion of TbSPPS

physiological function

Arabidopsis thaliana SPS1-overexpressing lines are much more resistant to photooxidative stress than the wild-type, showing marked decreases in leaf bleaching, lipid peroxidation and PSII photoinhibition under excess light. Comparison of the SPS1 overexpressors with other prenyl quinone mutants indicates that the enhanced phototolerance of the former plants is directly related to their increased capacities for plastoquinone-9 biosynthesis, phenotype, overview

enzyme SlSPS is necessary for normal chloroplast structure and function
physiological function
plastid isoforms of solanesyl-diphosphate synthase catalyze the elongation of the prenyl side chain involved in the plastoquinone-9 and plastochromanol-8 biosynthesis, plastochromanol-8 originates from a subfraction of the non-photoactive pool of plastoquinone-9
