- Abstract
ATP-binding cassette (ABC) transporter superfamily consists of a large group of proteins whose members participate directly in the bidirectional transport of a wide range of molecules across membranes. Plants have a number of ABC proteins, which are associated with a number of processes such as xenobiotic detoxification, disease resistance, transport of phytohormones, primary and secondary products, lipid catabolism, heavy metal tolerance, organoleptic and nutritional qualities of food. In Arabidopsis thaliana 132 ABC proteins have been identified via sequence similarity to known ABC transporters in other organisms. Recently, we cloned four pleiotropic drug resistance (PDR) transporter genes from Solanum tuberosum and studied their function during infection by Phytophthora infestans. The growing availability of sequence data offers the possibility to conduct studies about ABC genes to produce additional information on their genetic relationships, identification of variants and of new functional copies. In the present work, we analyzed and annotated new ABC transporters from four plant species (Solanum esculentum, Solanum tuberosum, Oryza sativa and Vitis vinifera) and produced a detailed inventory. Genomes of the various species differed significantly in the number of ABC proteins, which is especially expanded in S. tuberosum. The obtained data will contribute to a better understanding of the diversity of the plant ABC proteins providing clues to prioritize species-specific proteins for further plant-microbe interaction analysis.
