Use of thionin proteins and encoding nucleic acid fragments for the modification of plant defense, disease/pest resistance and protein storage

摘要

Disclosed is a substantially purified or isolated nucleic acid or nucleic acid fragment encoding a thionin (TH) polypeptide from a ryegrass (Lolium) species, or a functionally active fragment thereof. Also disclosed are complement and antisense sequences of the above. Sequences may be used to modify disease, pest resistance, plant defense and protein storage by way of introduction to the plant via vectors, or may be used as molecular marker
