NxtOil technology greatly increases energy density in plant biomass by switching on oil production in leaves, meaning that you can produce very large yields of vegetable oil in high biomass plant species. This is achieved by activating genes in leaf that are usually only active in seed, resulting in the synthesis and accumulation of oil droplets in cells.
