Powdery mildew, which is caused by f. sp. (), is a disease of wheat worldwide. Xiaobaidong is a Chinese wheat landrace, which still maintains good resistance against powdery mildew. To obtain more genetic markers closely linked to the powdery mildew resistance gene and narrow the candidate region for its isolation, new simple sequence repeats and cross intron-spanning markers were designed based on the genome sequence of cultivar Chinese Spring chromosome 7BL. The flanking markers and were found to be tightly linked to at genetic distances of 0.4 cM and 0.3 cM, respectively. The resistance locus was mapped to a 63.40 kb and 0.29 Mb region of the Chinese Spring genome and Zavitan genome, respectively. The linked markers of could be used as diagnostic markers for . The linked molecular markers and delineated genomic region in the sequenced Chinese Spring genome will assist the future map-based cloning of .

Powdery mildew (PM), is a significant fungal disease that poses a considerable threat to global agricultural productivity. Autophagy and programmed cell death (PCD) are crucial plant defense responses against PM. However, the role of metacaspases (MCAs) in mediating the interplay between autophagy and PCD in wheat's resistance to PM remains unknown.

Arbuscular mycorrhizal (AM) fungi are widely existing soil microorganisms that form symbiotic relationships with most terrestrial plants. They are important for enhancing adversity resistance, including resistance to disease and water stresses. Nevertheless, it is not clear whether the benefits can be maintained in regulating the occurrence of plant diseases under drought, flooding stress and during water restoration.

Mildiomycin is a representative peptidyl nucleoside antibiotic and was first isolated from , which has been used as an important biological agent to control powdery mildew in plants. Despite its importance, the biosynthetic pathways and regulatory mechanisms remain to be fully elucidated. In this study, we identified MilO as a positive pathway-specific regulator of mildiomycin biosynthesis in the heterologous host .
