Methods of identifying, selecting, and producing anthracnose stalk rot resistant crops
The field is related to plant breeding and methods of identifying and selecting plants with resistance to anthracnose stalk rot. Provided are methods to identify novel genes that encode proteins providing plant resistance to anthracnose stalk rot and uses thereof. These disease resistant genes are useful in the production of resistant plants through breeding, transgenic modification, or genome editing.
1. A method of introducing a heterologous NLR02 polynucleotide into a maize plant cell, wherein the NLR02 polynucleotide is associated with increased resistance to anthracnose stalk rot, the method comprising:
introducing the heterologous NLR02 polynucleotide into the maize plant cell, wherein the heterologous NLR02 polynucleotide is inserted into the maize plant genome at a non-natural location and comprises a polynucleotide sequence encoding a polypeptide comprising the sequence set forth in SEQ ID NO: 2.
2. The method of claim 1 , wherein the heterologous NLR02 polynucleotide comprises a polynucleotide sequence comprising at least 95% nucleic acid sequence identity to the sequence set forth in SEQ ID NO: 1 or SEQ ID NO: 3.
3. The method of claim 1 , wherein the heterologous NLR02 polynucleotide comprises a polynucleotide sequence comprising the sequence set forth in SEQ ID NO: 1 or SEQ ID NO: 3.
4. The method of claim 1 , further comprising regenerating a maize plant from the maize plant cell comprising the heterologous NLR02 polynucleotide inserted in the maize plant cell genome, wherein the regenerated maize plant comprises increased resistance to anthracnose stalk rot, compared to a control plant lacking the heterologous NLR02 polynucleotide.
