Gene Details:

• Gene ID:
• Gene Symbol: Pm1a
• Gene Name: NB-LRR protein
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Pm1a, the first powdery mildew resistance gene described in wheat, is part of a complex resistance (R) gene cluster located in a distal region of chromosome 7AL that has suppressed genetic recombination.
• The cloning of Pm1a and its identification in a highly rearranged region of chromosome 7A provides insight into the role of chromosomal rearrangements in the evolution of this complex resistance cluster.
• Two pathogen loci determine Blumeria graminis f. sp. tritici virulence to wheat resistance gene Pm1a.
• Pm1a encodes a typical NLR protein that triggers a hypersensitive immune reaction upon recognition of the pathogen-derived effector protein encoded by the avirulence (Avr) gene AvrPm1a, which was also cloned using a B. graminis bi-parental mapping population.
