AGRICHEMICAL SCREENS

摘要

The present invention discloses a method for identifying plant gene regulatory elements that respond to stimuli and affect transcription of structural genes operatively linked thereto. The invention further discloses a screening assay useful for identifying substances that can be used exogenously to activate plant trait-specific gene regulatory elements (e.g., promoters), thus causing expression of native or chimeric structural genes that are operatively linked thereto. Still further the invention discloses plant defense gene regulatory sequences (e.g., plant defense gene promoters, elicitor-regulated activator domains, upstream silencer domains and the like) that can be ''turned on'', induced or otherwise activated or deactivated by exogenous elicitors.
