Increasing plant growth by modulating omega-amidase expression in plants

摘要

The present disclosure relates to compositions and methods for increasing the leaf-to-root ratio of the signal metabolite 2-oxoglutaramate and related proline molecules in plants by modulating levels of ω-amidase to increase nitrogen use efficiency, resulting in enhanced growth, faster growth rates, greater seed and fruit/pod yields, earlier and more productive flowering, increased tolerance to high salt conditions, and increased biomass yields.

主权项

1. A transgenic plant comprising an ω-amidase transgene, wherein the ω-amidase transgene is operably linked to a root-preferred promoter and wherein the ω-amidase transgene encodes an ω-amidase protein having an amino acid sequence that is at least 90% identical to SEQ ID NO: 3, wherein the transgenic plant has increased biomass relative to a plant of the same species that does not comprise the ω-amidase transgene.
