Transgene construct to improve Fusarium head blight resistance in wheat and barley

摘要

Resistance of plants, particularly wheat and barley, to Fusarium head blight (FHB) and other Fusarium-related diseases may be induced or enhanced by transformation with a nucleic acid (DNA) construct comprising a nucleic acid sequence encoding the wheat ethylene-responsive transcription factor TaERF7-1 operatively linked to a promoter effective for expression in the plant. Plants transformed with the construct exhibit increased resistance to FHB and other Fusarium-related diseases in comparison to a non-transformed control plant. The transgenic plants may be produced from any plant, tissue or cell which is capable of regeneration, by transformation with the construct. Transformed plants, plant tissue or plant cells comprising the construct are selected, and the transgenic plant is generated therefrom.
