Abstract
Disclosed herein are compositions and methods for improving or enhancing pathogen resistance in legume plants. Compositions comprising polypeptides encoded by the CcRpp2-R1 and CcRpp2-R3 polynucleotides disclosed herein are useful in improving resistance in legumes to Asian Soybean Rust (ASR). Methods of using CcRpp2-R1 and CcRpp2-R3 genes to make transgenic ASR-resistant legume plants are also disclosed.
Claims21
A legume plant cell comprising an exogenous polynucleotide that encodes a polypeptide having at least 95% sequence identity with a full length sequence of SEQ ID NO:
- 2 or SEQ ID NO:
- 4, or a plant or plant part comprising a plurality of said legume plant cells.
The legume plant cell, plant, or plant part of 6, wherein the expression construct comprises a first polynucleotide having at least 95% sequence identity with the full length sequence of SEQ ID NO:
- 1 and a second polynucleotide having at least 95% sequence identity with the full length sequence of SEQ ID NO:
- 3, wherein each of said first and second polynucleotides are operably linked to a heterologous regulatory sequence operable in plant cells.
