The invention provides novel Ti-plasmid vectors for-medicated plant cell transformation. Plamsids of the invention are constructed with a DNA sequence (ie., a negative selectable maker or a DNA sequence that inhibits DNA unwinding) flanking the T-DNA bordered gene of interest that reduces or eliminates the occurrence of transformants with vector read-through DNA sequence. The invention also provides methods of plant cell transformation utilizing these novel vectors.

Plasmids for plant transformation and method for using the same

Nematode-inducible promoter sequences are disclosed. These sequences can be used for expressing DNA sequences in plant cells. Chimeric DNA constructs comprising the nematode-inducible promoter sequences operably linked to DNA to be expressed in plant cells are also disclosed. Plants comprising the chimeric DNA are provided. Methods for making plants that are resistant to plant parasitic nematodes are

Nematode-inducible regulatory DNA sequences

The present invention provides an isolated protein obtainable from a plant source which has anti-Phytophthora activity and a molecular weight of about 60&plusmn;5 kDa as judged by SDS PAGE-electrophoresis, an isolated DNA sequence comprising an open reading frame capable of encoding a protein according to the invention, preferably characterized in that it comprises an open reading frame which is capable of encoding a protein as represented by amino acids 1 to 540 of SEQ ID NO: 6, or the precursor of said protein, and DNA capable of hybridising therewith under stringent conditions. The invention further comprises plants incorporating chimeric DNA capable of encoding a protein according to the invention, and wherein the protein is expressed. Also methods are provided for combatting fungi, especially,, using a protein or a host cell capable of producing the protein.

Antifungal proteins, DNA coding therefor, and hosts incorporating same

An isolated DNA fragment that promotes root knot or cyst nematode indcuible transcription of a coding sequence downstream of and operably linked to the fragment in at least an,plant and a chimeric DNA sequence including the DNA fragment. Also, methods for the use of the DNA fragment.
