Identification of genetic loci and domestication gene GmZFP1 associated with soybean hypocotyl elongation in seedling stage by genome-wide association study.

ABSTRACT:

Background

The hypocotyl length and elongation is an important characteristic that affect the soybean seedling emergence and photosynthesis. However, the basic genetic mechanism of this feature remains incompletely understood.

Results

In this study, the hypocotyl length of four-day germinated soybean seedlings was evaluated before and after 24 h cultivation to assess hypocotyl elongation (HE) in 330 soybean accessions. Five quantitative trait loci (QTLs) that significantly associated with HE trait were detected by genome-wide association study (GWAS) in two models, and they are located on chromosome (Chr.) 2, 3, 11, 15, and 17, respectively. A total of 84 gene models have been found in HE QTLs candidate regions, and with a large proportion enriched in the biological processe
