The present invention is directed to promoters that have particular utility in driving root-specific expression of heterologous genes that impart increased agronomic, horticultural and/or pesticidal characteristics to a given transgenic plant. The present invention is also drawn to DNA molecules comprising the promoters of the invention and transformed plant tissues containing DNA molecules comprising a promoter of the invention operably linked to a heterologous gene or genes, and seeds thereof.
摘要:
The present invention relates to the field of biotechnology. More precisely, a genetic construct and method for producing a transgenic plant event, especially a sugarcane event {Saccharum spp.), which is resistant to infestation by the Diatraea saccharalis pest, popularly known as a pest, ordinary borer, reed borer or just borer is described. The invention describes the event, the methods for event identification as well as the insertion detection method based on the unique region of intersection between the insert and the host genome and the flanking regions that characterize it.
