Improved bioenergy value of residual rice straw by increased lipid levels from upregulation of fatty acid biosynthesis.

ABSTRACT:

Background

Rice (Oryza sativa) straw is a common waste product that represents a considerable amount of bound energy. This energy can be used for biogas production, but the rate and level of methane produced from rice straw is still low. To investigate the potential for an increased biogas production from rice straw, we have here utilized WRINKLED1 (WRI1), a plant AP2/ERF transcription factor, to increase triacylglycerol (TAG) biosynthesis in rice plants. Two forms of Arabidopsis thaliana WRI1 were evaluated by transient expression and stable transformation of rice plants, and transgenic plants were analyzed both for TAG levels and biogas production from straw.

Results

Both full-length AtWRI1, and a truncated form lacking the initial 141 amino acids (including the N-terminal
