Matrix attachment regions

摘要

Matrix attachment regions isolated from the 5' flanking region of endosperm-specific storage protein genes of monocotyledonous plants are provided. An exemplified matrix attachment region is derived from the 5' flanking region of the Bx7 gluten gene of Triticum aestivum. Recombinant nucleic acid molecules and plant vectors containing such recombinant nucleic acid molecules include DNA constructs having a promoter, a coding sequence, and a poly(A) addition site, the DNA constructs operably linked to at least one of the matrix attachment regions. Gene expression in transgenic plants, preferably monocotyledonous cereal crop species, is improved by transforming plants with such recombinant nucleic acid molecules.
