چکیده انگلیسی
Homeodomain leucine zipper IV (HD-ZIP IV) proteins are plant-specific transcription factors that play important roles in development of epidermal cell layers and cuticle formation. The functions of two HD-ZIP IV family genes, CD2 and Wo, have been well characterized in tomato (Solanum lycopersicum). CD2 and Wo are involved in cuticle biosynthesis and trichome formation, respectively. In this study, we identified 13 novel tomato HD-ZIP IV (SlHDZIV) genes. We analyzed the structures, chromosome locations, phylogeny, protein motifs, and expression profiles of these SlHDZIV genes. Gene structure analysis revealed that a module of 11 exons and 10 introns existed in the SlHDZIV genes. These genes were asymmetrically distributed on chromosomes, except on chromosome 4 and 5. Segmental duplication possibly contributed to the expansion of tomato HD-ZIP IV genes. The expression profiles of these genes revealed their broad expression pattern and high expression in young leaves and flowers. Each gene responded to more than one of different phytohormones [abscisic acid, ethephon, 4-(indolyl)-butyric acid, jasmonic acid, salicylic acid, gibberellic acid, and 6-benzylaminopurine] and four abiotic stress treatments (cold, heat, salt, and drought). This study provided significant insights into the diverse roles of SlHDZIV genes in tomato growth and development.
