Phylloquinone (2-methyl-3-phytyl-1,4-naphthoquinone; vitamin K(1)) is vital to plants. It is responsible for the one-electron transfer at the A(1) site of photosystem I, a process that involves turnover between the quinone and semi-quinone forms of phylloquinone. Using HPLC coupled with fluorometric detection to analyze Arabidopsis leaf extracts, we detected a third redox form of phylloquinone corresponding to its fully reduced - quinol-naphthoquinone ring (PhQH(2)). A method was developed to… CONTINUE READING
