Abstract

Expressed Sequence Tags (ESTs) isolated from the Western Corn Rootworm, Diabrotica virgifera virgifera LeConte, are disclosed. The invention encompasses nucleic acid molecules that encode D. v. virgifera protein homologs and fragments thereof. In addition, antibodies capable of binding the proteins are encompassed by the present invention. The disclosed ESTs have particular utility in isolating genes and promoters, identifying and mapping the genes involved in developmental and metabolic pathways, and determining gene function. The ESTs provide a unique molecular tool for the targeting and isolation of novel genes for plant protection and improvement. The invention also relates to methods of using the disclosed nucleic acid molecules, proteins, fragments of proteins, and antibodies, for example, for gene identification and analysis, and preparation of constructs.

Claims

1. A nucleic acid molecule complementary to all or part of a sequence selected from the group consisting of SEQ ID NO:

2491 and SEQ ID NO;

2492, wherein an antisense RNA expressed from said nucleic acid molecule is capable of reducing the expression of a D. v. virgifera gene comprising said SEQ ID NOs;

2491 or 2492, and wherein the nucleic acid molecule is operably linked to a heterologous promoter that causes transcription of DNA in plant cells.

26. The nucleic acid molecule of claim 1, wherein the nucleic acid molecule is complementary to all or part of SEQ ID NO:

2491.

27. The nucleic acid molecule of claim 26, wherein the nucleic acid molecule is complementary to all of SEQ ID NO:

2491.

28. The nucleic acid molecule of claim 1, wherein the nucleic acid molecule is complementary to all or part of SEQ ID NO:

2492.

29. The nucleic acid molecule of claim 28, wherein the nucleic acid molecule is complementary to all of SEQ ID NO:

2492.

30. The nucleic acid molecule of claim 1, wherein the nucleic acid molecule comprises a fragment of from about 15 to about 250 nucleotide residues complementary to a sequence selected from the group consisting of SEQ ID NO:

2491.

31. The nucleic acid molecule of claim 1, wherein the nucleic acid molecule comprises a fragment of from about 15 to about 250 nucleotide residues complementary to a sequence selected from the group consisting of SEQ ID NO:

2492.

32. A construct comprising the nucleic acid molecule of claim 1.

33. A transgenic plant comprising the nucleic acid molecule of claim 1.

34. The transgenic plant of claim 33, which is a corn plant.

35. A cell comprising the nucleic acid molecule of claim 1.

36. The cell of claim 35, wherein the cell is an Agrobacterium sp., E. coli or a plant cell.

37. The cell of claim 36, wherein the cell is a plant cell.

38. The cell of claim 37, wherein the cell is a corn plant cell.
