Abstract
A DNA fragment for directing the expression of foreign or endogenous genes or RNA in cells of monocot plants. The fragment comprises a sequence corresponding to a first part of a putative type I starch branching enzyme gene (wbeI) present in wheat and a 5'-region upstream of the gene, or a part of the sequence that is effective for increasing the expression of the foreign or endogenous gene in the plant cells. The indicated sequence contains two promoter regions, P1 and P2. A DNA fragment effective to increase expression comprises at least one of the promoter regions, or an effective part. The fragment can be obtained from a genomic library of wheat and can be fused to suitable genes and markers and inserted into suitable vectors for expression in transgenic monocot plants.
