What is A large‐scale genomic association analysis identifies a fragment in Dt11 chromosome conferring cotton Verticillium wilt resistance about?
## Summary Verticillium wilt (VW) is a destructive disease that results in great losses in cotton yield and quality. Identifying genetic variation that enhances crop disease resistance is a primary objective in plant breeding. Here we reported a GWAS of cotton VW resistance in a natural‐variation population, challenged by different pathogenicity stains and different environments, and found 382 SNPs significantly associated with VW resistance. The associated signal repeatedly peaked in chromosome Dt11 (68 798 494‐69 212 808) containing 13 core elite alleles undescribed previously. The core SNPs can make the disease reaction type from susceptible to tolerant or resistant in accessions with alternate genotype compared to reference genotype. Of the genes associated with the Dt11 signal, 25 genes differentially expressed upon __Verticillium dahliae__ stress, with 21 genes verified in VW resistance via gene knockdown and/or overexpression experiments. We firstly discovered that a gene cluster of L‐type lectin‐domain containing receptor kinase (__GhLecRKs‐V__.__9__) played an important role in VW resistance. These results proved that the associated Dt11 region was a major genetic locus re
