ALS3 PROMOTER

摘要

The Brassica ALS3 promoter is operably linked to a foreign structural gene to provide high level, and generally constitutive or tissue general expression of the structural gene in transformed plants. The Brassica ALS3 promoter exhibits a non-tissue-preferred mode of expression at a level comparable to, and in some cases higher than, the widely used CaMV 35S promoter. Accordingly, DNA constructs comprising the Brassica ALS3 promoter operably linked to any number of different gene coding regions can be used for constitutive and tissuegeneral expression of the gene in transformed plants. The Brassica ALS3 promoter is used to direct expression of agronomically important genes and selectable marker genes.
