Disclosed herein are transgenic cells expressing a heterologous nucleic acid encoding a prephenate dehydrogenase (PDH) protein, a heterologous nucleic acid encoding a homogentisate solanesyl transferase (HST) protein, a heterologous nucleic acid encoding a deoxyxylulose phosphate synthase (DXS) protein, or a combination of two or more thereof. In particular examples, the disclosed transgenic cells have increased plastoquinone levels. Also disclosed are methods of increasing cell growth rates or production of biomass by cultivating transgenic cells expressing a heterologous nucleic acid encoding a PDH protein, a heterologous nucleic acid encoding an HST protein, a heterologous nucleic acid encoding a DXS protein, or a combination of two or more thereof under conditions sufficient to produce cell growth or biomass.
A transgenic photosynthetic cell comprising one or more heterologous nucleic acids encoding:
The transgenic cell of claim 12, wherein the expression vector comprises a plasmid.
A method of producing a photosynthetic cell comprising an increased amount of plastoquinone compared to a control cell, comprising expressing in the cell one or more heterologous nucleic acids encoding:
