DEVELOPING CROP PLANTS FOR PRODUCTION OF BIODEGRADABLE PLASTICS BY TRANSGENIC APPROACHES

White pollution caused by petroleum-derived plastic wastes is harmful to agriculture and ecosystem seriously.As a sustainable alternative of conventional plastic,biodegradable plastic is environmental safety and renewable.Biomass polymers such as Poly-β-hydroxybutyrate(PHB) and cyanophycin are high-molecular-weight compounds for the production of biodegradable plastic.The article is focused on the current progress on the development of the transgenic crops accumulating PHB and cyanophycin by the gene engineering approach.The challenge and prospect of transgenic plant based production of biodegradable plastic was also discussed.
