Modification of cereal grain hardness via expression of puroindoline proteins

摘要

This invention provides expression cassettes and vectors comprising a recombinant nucleic acid which comprises a nucleic acid sequence encoding a functional puroindoline B. This invention further provides such cassettes and vectors wherein the nucleic acid sequence encoding a functional puroindoline B is operably linked to a promoter. The invention also provides methods of producing plants with soft grain by transforming them with such expression cassettes and vectors, as well as the cells and plants produced by such methods.
