"-" corresponds to no genes with homology to the gene listed on the left. Accession numbers listed refers to protein sequences in the NCBI Protein database. Genes were identified using annotations provided in Genebank followed by BLASTx searches of the genomes using previously characterized homologs. Auxin efflux carrier proteins were identified using Transporter Classification on the JGI IMG database.
