摘要
Dear editor,Powdery mildew(PMD)is a widespread,fungal-borne disease that impacts crop yield worldwide.In soybean,PMD is caused by the fungal pathogen,Microsphaera diffusa.The most efficient and economic strategy for PMD management with minimal environmental impact is through the deployment of resistance genes(Dangl et al.,2013;Hafeez et al.,2021).Although resistant genes against PMD have been identified in some crops,identification of those in soybean remains elusive.Several independent reports have consistently mapped the PMD-resistance locus to the end of Chr 16(Kang and Mian,2010;Jun et al.,2012;Jiang et al.,2019),however,the underlying gene that confers PMD resistance in soybean has yet to be cloned.Identification of the resistance-to-M.diffusa 1(Rmd1)gene is critical for the breeding of resistant soybean varieties,and thus control of PMD in this important crop.
