Common wheat is a leading global food crop that impacts security. Wheat powdery mildew (PM), caused by Blumeria graminis f. sp. tritici (Bgt), poses significant threat to grain yield and flour quality. The identification utilization of broad-spectrum resistance genes against PM are essential for effective disease control. spectrum test during the seedling stage adult were conducted evaluate landrace Honghuamai (HHM). Five segregating populations investigated assess inheritance in HHM. To map its resitance gene, bulked segregant analysis, molecular mapping comparative genomic analysis also used present study. HHM shows remarkable field nearly immune all 25 Bgt isolates tests, making it an excellent source resistance. was determined single dominant temporarily named PmHHM. It then fine-mapped interval with genetic distance 0.0031 cM physical 187.4 kb on chromosome 4AL Chinese Spring reference sequence v.2.1. Four identified target region, three which encode nucleotide-binding leucine-rich repeat (NLR) proteins. Comparative revealed presence/absence variations (PAVs) PmHHM locus among common varieties. These closely linked markers will not only benefit cloning gene underlying but facilitate efficient breeding programs.

Powdery mildew is a highly destructive disease that greatly reduces both the yield and quality of wheat. As there limited research on changes in microorganism community caused by powdery infection different tissue parts, especially after spike infection, this study aimed to examine surface microorganisms infected healthy wheat plants. Samples were collected from leaves spikes, number operational taxonomic units (OTUs), diversity index, abundance, metabolic microbial analysed using 16S rRNA amplicon sequencing technology. Through identification tissues, 24 phyla identified leaves, 20 spikes. The dominant bacterial observed Proteobacteria Bacteroidetes . At genus level, 19 genera detected 11 Notably, total exceeded Pseudomonas , Sphingomonas Pantoea species 37 types 35 included Pedobacterium panaciterrae baetica rhizophaerae aerolata analysis conducted revealed incidence was greater plots situated closer obstacles than other plots. when with mildew, results indicated spikes significantly impacted, response being more pronounced leaves. Different leaf surface, pathway are mainly regulation. These provide theoretical support for prevention control crops.
