Identification and Bioinformatics Analysis of ABC Transporter Gene Family in Hydrangea under Aluminum Stress

ABC transporters is a type of transmembrane widely found in prokaryotes and eukaryotes. They are involved plant signal transduction, secondary metabolite transport abiotic stress response. According to the transcriptome data Hydrangea, this study was proposed analyze members transporter gene family, physical chemical properties, structure, phylogeny expression patterns under aluminum using bioinformatics method. The results showed that there were 48 family which belonged 7 subfamilies respectively, among C subfamily had most members; subcellular localization 50% located on plasma membrane; properties domain analysis hydrophobic proteins, different specific conserved motifs, but motif1 motif2 all present hydrangea transporter; A phylogenetic tree constructed with 129 Arabidopsis thaliana , from Hydrangea clustered into respectively. profile HmABCA1, HmABCC1, HmABCC6, HmABCC14  and HmABCD1  gene upregulated root HmABCG1 up-regulated leaves after treatment. provide reference for further tolerance regulation genes hydrangea.
