Abstract
Membrane traffic is essential in cellular metabolism and activities of living organs. In plant, transport systems play roles in the acquisition of essential elements as well as in the maintenance of ion homeostasis responding to various environmental stresses. To perform comprehensive analysis of the transporter coding genes in plant species, possible transporter genes classified into 59 families were predicted by using profile and similarity search against the proteome data of Arabidopsis, poplar, rice as well as the UniGene data of 16 plant species. Ortholog prediction by all against all similarity search and phylogenetic profiling of transporter genes were performed to characterize constitution of genes of each family. In this study, we report the results of genome wide comparison in plant transporter genes. Furthermore, these data of possible plant transporter genes were integrated into a relational database with the annotations of predicted domain organization and transmembrane regions.
