主 题：Solanum tuberosum(potato) Autotetraploid cultivars Genome-wide association study(GWAS) Domestication Genome Resequencing
摘 要：Potato is the fourth most important food crop in the *** with a long history for breeding approaches,genomic information and association between genes and agronomic traits remain largely unknown particularly in autotetraploid potato cultivars,which limit the molecular breeding *** resequencing the genome of 108 main cultivar potato accessions with rich genetic diversity and population structure from International Potato Center,with approximate 20-fold coverage,we revealed more than 27 million Single Nucleotide Polymorphisms and~3 million Insertion and Deletions with high quality and *** analysis and genome-wide association studies(GWAS)identified candidate loci related to photoperiodic flowering time and temperature sensitivity as well as disease resistance,providing informative insights into the selection and domestication of cultivar *** addition,GWAS with GWASploy for 25 agronomic traits identified candidate loci by association signals,especially those related to tuber size,small-sized tuber weight and tuber thickness that was also validated by transcriptome *** study provides a valuable resource that facilitates the elucidation of domestication process as well as the genetic studies and agronomic improvement of autotetraploid potato.
