Cd can affect the crop’s growth and development and enter the body to affect human health through the food chain. Existing research shows that the Nramp protein family has played a key role in the regulation process of Cd absorption and transport in the model plant Arabidopsis and rice. However, the Nramp genes involved in the Cd absorption and transport have rarely been reported in the soybean. Through the analysis of soybean database, we found a member of Nramp family, named GmNramp1 (Glyma07g02680). Analysis of the RT-PCR results shows that the 75 μmol·L-1 CdCl2 treatment of soybean root, cotyledon, hypocotyl, and leaves for different time decreases the expression of the GmNramp1 gene. And the transcriptome sequencing result of soybean root treated with Cd also supports the same conclusion of Nramp gene function. The results show that GmNramp1 gene may participate in the absorption and transport process of Cd in soybean. This study provides a theore-tical basis and genetic resources for breeding soybean resistant to heavy metals. %U http://www.cje.net.cn/EN/abstract/article_22542.shtml
