玉米种子萌发相关性状的全基因组关联分析OA北大核心CSCDCSTPCD
Genome-wide Association Studies of Seed Germination Related Traits in Maize
种子萌发是出苗的前提, 对玉米产量影响重大.为了解玉米种子萌发相关性状的遗传机制, 本研究对476份玉米自交系种子萌发相关的6个性状进行调查, 结合125万个(1.25M) SNP标记, 利用3种统计模型(Q, K, Q+K)进行全基因关联分析(GWAS).结果表明 K 模型能够较好地评价吸胀前重量、吸胀前体积、吸胀后重量、吸胀后体积和吸胀体积5个性状; Q+K 模型能更好地评价吸胀重量性状.基于这6个性状的最优模型的 GWAS 结果, 共检测到…查看全部>>
Germination is important for seed emergence, which has significant impact on maize yield. To reveal the genetic mechanism of maize seed germination, we investigated six traits related to seed germination using 467 diverse inbred lines. The genome-wide association studies (GWAS) between the six traits and 1.25M SNPs were implemented in three different models (Q model, K model, and Q+K model). The K model was much better than the other two models for weight be…查看全部>>
