Identification and characterization of a novel powdery mildew resistance gene PmCWI45575 in wild emmer wheat
We identified a novel powdery mildew resistance gene, PmCWI45575, from wild emmer wheat and physically mapped it to a 5.3 Mb interval on chromosome arm 4AL. Comparison of physical location with previously reported Pm genes on 4AL suggested that PmCWI45575 is likely a novel resistance gene. BSR-Seq-based transcriptomic analysis revealed enriched defense-related pathways, providing molecular insights into the resistance mechanism. The development and validation of closely linked molecular markers offer practical tools for marker-assisted selection in wheat resistance breeding.
