摘 要：As a second messenger,calcium participates in a large number of processes of abiotic stresses and plays an important role in the process of response to adversity signaling process in *** transmits signals to downstream through the combination with protein phosphatase B subunit like protein and calcineurin B-like protein-interacting protein kinase（CIPK）plays a key regulatory role in the growth,development and adversity of *** present,the research on the CIPK gene family mainly focused on the model plants such as Arabidopsis thaliana and rice,but the reports of the CIPK gene family in cotton were *** the present study,the identification of the CIPK gene family was carried out on the whole genomes of diploid cotton（Gossypium raimondii L.）and Asian cotton Shixiya I（Gossypium arboreum L.）,and bioinformatics analysis such as gene structure was conducted on the identified CIPK gene family members to study the phylogenetic relationship and analyze the transcript expression of the CIPK gene family in different tissues in different *** results demonstrated that the CIPK gene family was unevenly distributed whether in the cotton D genome chromosome or A genome chromosome.A total of 41 CIPK genes were identified in the D genome of the Gossypium raimondii,mainly distributed in chromosome 10and chromosome 9 but not chromosome 2 or chromosome 12;A total of 39 CIPK genes were identified in the A2 genome of the diploid Gossypium arboreum L.,mainly distributed in chromosome 8and chromosome 11 but not chromosome 2 or chromosome *** CIPK gene family in cotton can be classified into two types according to the structures of the genes,the intron rich type and intronless type（or rare intron type）,which are similar to those of the CIPK gene families of Arabidopsis thaliana,maize,rice and other *** analysis revealed that the CIPK gene family members in cotton had high evolutionary relationships with those of the dicotyledon Arabidopsis thaliana an
