Key Features
Description
The researchers have identified two promoters involved in the expression of different avenacin biosynthesis genes in the roots of oats. Reporter fusion experiments have demonstrated the potential use of these promoters for root-specific expression of heterologous genes in both monocot (rice) and dicot (Arabidopsis) crop species, with similar expression profiles to those shown for their native genes in oats. Update: Sad1 and Sad2 promoters drive root-specific expression in wheat.
