The protein encoded by LoERF017 is predicted to include only one AP2 domain, and its secondary structure includes α-helix (30.43%), random coil (54.11%), extended strand 12.56%), and β-sheet (2.9%). Subcellular localization of the gene showed that LoERF017 was located in the nucleus. The results of qRT-PCR showed that the expression level of LoERF017 gene in L.kaempferi had certain tissue specificity. The expression of this gene in root was the highest, the expression in stem was the lowest, and the expression in leaves was middle. Under drought stress, the expression of LoERF017 gene increased in the root, but decreased after rehydration. It was preliminarily predicted that this gene is mainly expressed and functions in root of L.kaempferi, and it was speculated that LoERF017 might be related to drought resistance. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2020.04.015
