a: The full names of the abbreviations, ATF, APC, AAP, LHT, ProT, GAT, ANT, AUX, ATL, VAAT, CAT, ACT and PHS, can be found in the main text. AAAP: amino acid/auxin permease; TTP: tyrosine-specific transporter; A. thaliana: Arabidopsis thaliana; R. communis: Ricinus communis; M. truncatula: Medicago truncatula; P. edulis: Phyllostachys edulis. b: The ATL and VAAT subfamilies are also known as ATLa and ATLb, respectively. c: TTP, tyrosine-specific transporter, is classified in APC family in reference [9] but is classified in ATF family in reference [22]. d: N.D. not determined. e: This contains the members of VAAT subfamily. f: This contains the members of ATL and VAAT subfamily.
