INCREASING CARBON FLOW FOR POLYHYDROXYBUTYRATE PRODUCTION IN BIOMASS CROPS

Transgenic plants, transgenic plant material, and transgenic plant cells for the improved synthesis of polyhydroxyalkanoates, preferably poly(3-hydroxybutyrate) (also referred to as PHB), have been developed. In one embodiment, carbon flow is modulated to increase production of PHB. Preferred plants...

Zusammenfassung:	Transgenic plants, transgenic plant material, and transgenic plant cells for the improved synthesis of polyhydroxyalkanoates, preferably poly(3-hydroxybutyrate) (also referred to as PHB), have been developed. In one embodiment, carbon flow is modulated to increase production of PHB. Preferred plants that can be genetically engineered to produce PHB include plants that produce a large amount of lignocellulosic biomass that can be converted into biofuels, such as switchgrass, Miscanthus, Sorghum, sugarcane, millets, Napier grass and other forage and turf grasses. An exemplary plant that can be genetically engineered to produce PHB and produces lignocellulosic biomass is switchgrass, Panicum virgatum L. A preferred cultivar of switchgrass is Alamo. Other suitable cultivars of switchgrass include, but are not limited to, Blackwell, Kanlow, Nebraska 28, Pathfinder, Cave-in-Rock, Shelter and Trailblazer. Cette invention concerne des plantes transgéniques, du matériel de plantes transgéniques, et des cellules de plantes transgéniques qui ont été mis au point pour la synthèse améliorée des polyhydroxyalcanoates, de préférence, le poly(3-hydroxybutyrate) (également appelé PHB). Dans un mode de réalisation, le flux de carbone est modulé pour augmenter la production du PHB. Les plantes préférées qui peuvent être génétiquement modifiées pour produire du PHB comprennent les plantes qui génèrent une grande quantité de biomasse lignocellulosique qui peut être convertie en biocarburants, telles que le panic érigé ( » Switchgrass »), le Miscanthus, le Sorghum, la canne à sucre, les millets, l'herbe Napier et autres graminées fourragères et à gazon. Une plante donnée en exemple qui peut être génétiquement modifiée pour produire du PHB et génère une biomasse lignocellulosique est le panic érigé, Panicum virgatum L. Un cultivar préféré de panic érigé est Alamo. D'autres cultivars convenables de panic érigé comprennent, entre autres, Blackwell, Kanlow, Nebraska 28, Pathfinder, Cave-in-Rock, Shelter et Trailblazer.
