Basic biological analysis of ZmABCB15. a Evolutionary tree analysis of ZmABCB15 with other ABCB family members from different plants. Red box indicated the position of ZmABCB15. b Protein structure analysis of ZmABCB15. Yellow boxes indicated trans-membrane domains (TMs) and blue boxes indicated P-loop NTH domains. Numbers indicated the position of each domain in the ZmABCB15 protein. c Trans-membrane structure analysis of ZmABCB15 protein. Red lines indicated “transmembrane” structure, blue lines indicated “inside” structure, and purple lines indicated “outside” structure. d Multiple sequence alignment of ZmABCB15 and other ABCB members from different plants. Yellow lines indicated TM, and blue lines indicated P-loop NTH domains
