| 1 | Genome-wide association study identifies novel loci and candidate genes for drought stress tolerance in rapeseed显示文摘Rapeseed(Brassica napus)is one of the most important oil crops worldwide;however,drought seriously curtails its growth and productivity.Identifying drought-tolerant germplasm is an efficient strategy for addressing water shortages.Here,we phenotyped a panel of 264 B.napus accessions at full-bloom stage using water loss ratio(WLR)as drought-tolerant index.It identified 8 low-WLR and 6 high-WLR accessions,regarded as droughttolerant and drought-sensitive,respectively.Comparing with drought-sensitive accessions at the seedling stage,drought-tolerant accessions had shown better performance in maintaining fresh and dry weights,and performed the higher expression of drought-induced marker genes under drought stress.Subsequently,a total of 139 SNPs(single nucleotide polymorphisms)were identified associated with the WLR using a genome-wide association study(GWAS)among 264 B.napus accessions,with the largest number SNPs at chromosome A10,and 13 SNPs significantly were associated with the WLR(-log_(10)(p-value)>6).Furthermore,4 putative candidate genes(BnaC09.RPS6,BnaC09.MATE,BnaA10.PPD5 and BnaC09.Histone)were screened involving in drought tolerance in B.napus.Together,our results highlight the WLR's importance in drought tolerance and establish the foundation for improving WLR-associated drought tolerance in rapeseed. | Ali Shahzad Minchao Qian Bangyang Sun Umer Mahmood Shengting Li Yonghai Fan Wei Chang Lishi Dai Hong Zhu Jiana Li Cunmin Qu Kun Lu | 2021 | Oil Crop Science2021，6，1： | 1 |
