Genes coding for avenin-like proteins (ALP) represent a new family of wheat storage protein genes. To find a wheat endosperm-specific promoter, a 1644-bp fragment upstream of the ALP type-B gene (GenBank accession number JN622144) was isolated. The important promoter elements

Protocols

To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.
