Genome-wide evolution and function analysis of ALOG gene family in cotton.
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.

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.
