Gene Details:

• Gene ID:
• Gene Symbol: Pm36
• Gene Name: powdery mildew resistance 36
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• The isolation of broad-spectrum powdery mildew resistance gene Pm36, originated from wild emmer wheat, that encodes a tandem kinase with a transmembrane domain (WTK7-TM) through the combination of map-based cloning, PacBio SMRT long-read genome sequencing, mutagenesis, and transformation.
• Haplotype analysis uncovers that Pm36 is an orphan gene only present in a few wild emmer wheat, indicating its single ancient origin and potential contribution to the current wheat gene pool.
• Pm36, a wild emmer wheat (WEW)-derived powdery mildew resistance gene, was identified and mapped on chromosome arm 5BL in the tetraploid WEW-durum introgression line 5BIL-29.
• Pm36 encodes a unique tandem kinase with a transmembrane domain in the C-terminus (WTK7-TM).
• Pm36 is only present in a few WEW populations with a single ancient origin and can potentially contribute to modern wheat improvement.
