Arabidopsis	At1g31770	Positive regulator of plant growth which acts as an efflux pump involved in the major root-to-shoot (acropetal) long-distance cytokinin (CK) transport via the xylem sap.	ABCG9, ABCG11 and ABCG14 ABC transporters are required for vascular development in Arabidopsis.; 2013; DOI: 10.1111/tpj.12334; PMID: 24112720; https://pubmed.ncbi.nlm.nih.gov/24112720/ | Arabidopsis ABCG14 protein controls the acropetal translocation of root-synthesized cytokinins.; 2014; DOI: 10.1038/ncomms4274; PMID: 24513716; https://pubmed.ncbi.nlm.nih.gov/24513716/ | Arabidopsis ABCG14 is essential for the root-to-shoot translocation of cytokinin.; 2014; DOI: 10.1073/pnas.1321519111; PMID: 24778257; https://pubmed.ncbi.nlm.nih.gov/24778257/ | Cytokinin Response Factor 6 Represses Cytokinin-Associated Genes during Oxidative Stress.; 2016; DOI: 10.1104/pp.16.00415; PMID: 27550996; https://pubmed.ncbi.nlm.nih.gov/27550996/ | A Role of Cytokinin Transporter in Arabidopsis Immunity.; 2017; DOI: 10.1094/mpmi-01-17-0011-r; PMID: 28398838; https://pubmed.ncbi.nlm.nih.gov/28398838/
