Arabidopsis	At3g53480	Together with ABCG36, regulates auxin homeostasis and responses by playing a dual role in coumarin (and derivatives) and in the auxin precursor indole 3-butyric acid (IBA) efflux transport, thus influencing roots and root hairs development.	Arabidopsis PIS1 encodes the ABCG37 transporter of auxinic compounds including the auxin precursor indole-3-butyric acid.; 2010; DOI: 10.1073/pnas.1005878107; PMID: 20498067; https://pubmed.ncbi.nlm.nih.gov/20498067/ | Involvement of the ABCG37 transporter in secretion of scopoletin and derivatives by Arabidopsis roots in response to iron deficiency.; 2014; DOI: 10.1111/nph.12471; PMID: 24015802; https://pubmed.ncbi.nlm.nih.gov/24015802/ | Arabidopsis Transporter ABCG37/PDR9 contributes primarily highly oxygenated Coumarins to Root Exudation.; 2017; DOI: 10.1038/s41598-017-03250-6; PMID: 28623273; https://pubmed.ncbi.nlm.nih.gov/28623273/
