摘要： Calmodulin (CaM) is considered as the most significant Ca2+ signaling messenger that mediate various biochemical and physiological reactions. IQ domain (IQD) proteins are plant specific CML/CaM calcium binding which are characterized by domains of 67 amino acids. 50, 50, 94, and 99 IQD genes were detected from G. arboreum (A2), G. raimondii (D5), G. barbadense (AD2) and G. hirsutum (AD1) respectively. Existence of more orthologous genes in cotton species than Arabidopsis, advocated that polyploidization produced new cotton specific orthologous gene clusters. Duplication of gene events depicts that IQD gene family of cotton evolution was under strong purifying selection. G. hirsutum exhibited high level synteny. GarIQD25 exhibited high expression in stem, root, flower, ovule and fiber in G. arboreum. In G. raimondii, GraIQD03 demonstrated upregulation across stem, ovule, fiber and seed. GbaIQD11 and GbaIQD62 exhibited upregulation in fiber development in G. barbadense. GhiIQD69 recognized as main candidate genes for plant parts, floral tissues, fiber and ovule development. Promotor analysis identified cis-regulatory elements were involved in plant growth and development. Overwhelmingly, present study paves the way to better understand the evolution of cotton IQD genes and lays a foundation for future investigation of IQD in cotton.
