Welcome to ABC !

ATP binding cassette (ABC) transporter genes are ubiquitous across the three domains of life: Eukarya, Eubacteria and Archaea, which actively mediate the transport of a wide range of molecules, such as organic acids, metal ions, phytohormones and secondary metabolites. ABC transporters comprise at least four domains: two transmembrane domains (TMDs) embedded in the membrane bilayer, and two nucleotide-binding domains (NBDs) located in the cytoplasm. In plant, ABC transporters are grouped into eight different subfamilies (ABCA-ABCG and ABCI). ABC transporters, as one of the most widely functional protein superfamilies, are involved in plant physiological processes, such as plant hormone transport, nutrient uptake by organisms, stomatal regulation, environmental stress responses, and the interaction between plants and microorganisms.
