摘要： Eggplant (Solanum melongena L.) is an important vegetable cultivated in Asia, Africa and southern Europe and, following tomato and pepper, ranks as the third most important solanaceous vegetable crop. The Dof (DNA-binding with one finger) family is a group of plant-specific transcription factors that play important roles in plant growth, development, and response to biotic and biotic stresses. The genes in the Dof family have been identified and analysed in many plant species, but the information remains lacking for eggplant. In the present study, we identified 29 SmeDof members from the eggplant genome database, which were dassifed into nine subgroups. The phylogeny, gene structure, conserved motifs and homologous genes of SmeDof genes were comprehensively investigated. Subsequently, we analysed the expression patterns of SmeDof genes in six different eggplant subspecies. The results provide novel insights into the family of SmeDof genes and will promote the understanding of the structure and function of Dof genes in eggplant, and the role of Dof expression during stress.
