Genome wide association study and transcriptome analysis identify candidate genes regulating wheat coleoptile length.

ABSTRACT: Coleoptile length, in wheat, is a significant agronomic trait impacting yield by facilitating the successful establishment of seedlings. In arid regions, varieties possessing longer coleoptile can evade harsh conditions by deep sowing, paving the way for improved yield. However, the study of genes involved in coleoptile development is insufficient. In this study, a high-density 660 K SNP array was used for genome-wide association study (GWAS) on coleoptile length in 150 wheat varieties. The findings revealed the detection of 353 significantly associated SNPs across all environments. The integration of linkage disequilibrium analysis and haplotype analysis mined 23 core QTLs capable responsible for the stable regulating coleoptile length in wheat. In wheat varieties characterized by extende
