摘要： Members of DOMAIN OF UNKNOWN FUNCTION 679 membrane protein (DMP) gene family, a type of plant specific membrane proteins, have been proposed to function in various physiological processes such as reproductive development and senescence in plants. Here, a total of 174 DMP genes were identified and analyzed in 16 plant species (including 58 DMPs in four cotton species). Phylogenetic analysis showed that these DMPs could be clustered into five subfamilies (I-V). 137 duplicated cotton gene pairs were identified and most duplicate events were formed by whole-genome duplication (WGD)/segmental duplications. Expression analysis revealed that most of cotton DMPs were mainly expressed in the reproductive organs (the sepal, petal, pistil and anther) and the fiber of secondary cell wall stage. GhDMPs promoter regions containing the different cis-elements also showed different responses to abiotic stress. In addition, gene interaction networks showed that DMPs, as an endomembrane system, were involved in plant senescence process and flower reproductive development. We speculated GhDMP8-A/-D, GbDMP8-A/-D could be used as some candidate gene for inducing cotton haploid. This genome-wide study provides a systematic analysis of the cotton DMP gene family, and further insights towards understanding the potential functions of candidate genes. (c) 2021 Elsevier B.V.
