- W2796005065 abstract "Phylloquinone (PhQ) is found predominantly in thylakoid membranes of photosynthetic tissues where it functions in photosystem I electron transport. PhQ has also been detected in plasma membranes, but neither the molecular basis nor the significance of this non-canonical pathway has been elucidated. Here we provide evidence of plasma membrane PhQ biosynthesis in a non-photosynthetic holoparasite Phelipanche aegyptiaca. A non-photosynthetic role is supported by transcription of the entire suite of PhQ biosynthetic genes, plasma membrane-localization of the terminal enzymes, and detection of PhQ in Phelipanche seeds. Analysis of PhQ-coexpressed genes in the holoparasite revealed increased cellular commitment to oxidation-reduction and defense relative to photosynthetic parasites. Coexpression network inference identified oxidoreductases involved in plasma membrane electron transport, implicating PhQ in a transmembrane redox relay associated with parasitism. Plasma membrane PhQ biosynthesis is also predicted to occur in photoautotrophic taxa via alternative splicing, suggesting non-plastidial PhQ is evolutionarily conserved." @default.
