PATHOGEN-RESISTANT MONOCOT PLANTS AND METHOD

摘要

A method of producing resistance to a plant microbial pathogen in the seeds of a monocot plant is disclosed. A plant is stably transformed with a chimeric gene having (i) a transcriptional regulatory region induced during seed development, and (ii) an inhibitory gene sequence operably linked to the transcriptional regulatory region for induction of an inhibitory transcript RNA during seed development. The biological action of the transcript RNA, at the levels induced, leads to an accumulation of the secondary intermediate metabolite at levels toxic to the microbial pathogen. Pathogen resistant plants and seeds from the method are also disclosed.
