Abstract

Background: The ALOG (Arabidopsis thaliana LSH1 and Oryza sativa G1) gene family is a class of transcription factors present in various plants. To elucidate the roles of ALOG genes in cotton, we systematically investigated the ALOG gene family across four cotton species (Gossypium hirsutum, Gossypium barbadense, Gossypium arboreum and Gossypium raimondii).

Results: In this study, a total of 43, 42, 23 and 27 ALOG genes were identified from G. hirsutum, G. barbadense, G. arboretum and G. raimondii, respectively. The results indicated that cotton ALOG gene duplications originated before the speciation of Gossypium species, whole genome duplication, segmental duplication and transposable elements all play important roles in its expansion. In addition, cotton ALOG genes had undergone purifying selection during the evolution. Cis-element analysis revealed that TATA-box and CAAT-box are the most abundant in the promoters of cotton ALOG genes. Transcriptome analysis showed that the expression of ALOG genes in specific tissue is significantly higher than that in other tissues.

Conclusion: This study enhances our comprehension of cotton ALOG genes, and these findings lay the foundation for functional characterizations of ALOG gene family.

棉花ALOG基因家族的全基因组进化与功能分析。

背景：ALOG （Arabidopsis thaliana LSH1和Oryza sativa G1）基因家族是存在于多种植物中的一类转录因子。为了阐明ALOG基因在棉花中的作用，我们系统地研究了4种棉花（绵棉、巴氏棉、木棉和雷蒙地棉）ALOG基因家族。结果：本研究共从毛毛藓、巴氏藓、树藓和雷蒙地中分离到43个、42个、23个和27个ALOG基因。结果表明，棉ALOG基因的复制在棉物种形成之前就已经存在，全基因组复制、片段复制和转座因子在其扩展过程中都起着重要作用。此外，棉花ALOG基因在进化过程中经历了纯化选择。顺式元素分析表明，棉花ALOG基因启动子中TATA-box和CAAT-box最为丰富。转录组分析表明，ALOG基因在特定组织中的表达明显高于其他组织。结论：本研究提高了我们对棉花ALOG基因的认识，为ALOG基因家族的功能表征奠定了基础。

期刊介绍： Frontiers in Genetics publishes rigorously peer-reviewed research on genes and genomes relating to all the domains of life, from humans to plants to livestock and other model organisms. Led by an outstanding Editorial Board of the world’s leading experts, this multidisciplinary, open-access journal is at the forefront of communicating cutting-edge research to researchers, academics, clinicians, policy makers and the public. The study of inheritance and the impact of the genome on various biological processes is well documented. However, the majority of discoveries are still to come. A new era is seeing major developments in the function and variability of the genome, the use of genetic and genomic tools and the analysis of the genetic basis of various biological phenomena.
