Abstract: ZIP gene family is one of the most important metal cation transporter gene family within the organism.This work is to obtain the systematic biological information of GhZIP gene family through comprehensive analysis and identification of the Gossypium hirsutum genome sequence.Comparative genomics approach was used throughout this research,45 GhZIP genes were identified from the genome sequence database of allotetraploid cotton ( Gossypium hirsutum L.acc.TM-1).This GhZIP genes were found to be distributed on 22 other subgenomes except for A04,A09,D04 and D09.D subgenomes was 5 more GhZIP genes than A subgenomes.There were 16 pairs of GhZIP genes in the A and D subgenomes with one-to-one correspondence relationship.Transmembrane domain was detected in 44 GhZIP genes,among them 36 GhZIP genes had 6-9 transmembrane domains.20 GhZIP genes had histidine-rich domain which localized at variable region of membrane inner.The result of subcellular localization indicated that only one GhZIP gene was not locate in plasmembrane.A Blast search on the NCBI EST database of Gossypium hirsutum showed that 21 GhZIP genes with no matching EST sequence,and the other 24 GhZIP genes were expressed in various tissues of root,stem,leaf,flower,ovules,fiber,et al.18 members in this 24 GhZIP genes were expressed in root and/or stem.The study results of this paper would provide an theoretical basis on cloning and functional research of GhZIP genes.
