Catalysis of the reaction: all-trans-nonaprenyl diphosphate + H+ + homogentisate = 2-methyl-6-all-trans-nonaprenylbenzene-1,4-diol + CO2 + diphosphate. 2-methyl-6-solanyl-1,4-benzoquinonone is also known as 2-methyl-6-solanesylplastoquinol and all-trans-nonaprenyl diphosphate as solanesyl diphosphate.
