Modification of cereal grain hardness via expression of puroindoline proteins

摘要

A method of producing a transgenic plant with softer textured grain, the plant derived from at least one parent plant with hard textured grain, the method comprising the steps of: introducing a nucleic acid sequence which operably encodes a puroindoline protein into a cell from the parent plant, wherein the nucleic acid sequence hybridizes under stringent conditions to a nucleic acid sequence selected from the group consisting of SEQ ID NO: 1 and SEQ ID NO: 3; and generating a progeny plant from the cell containing the nucleic acid sequence. Wherein the progeny plant is selected from the group consisting of durum wheat, sorghum, rice, barley and maize.
