Project description:The emergence of eusociality is one of the major transitions in evolution. There have been several investigations into the reasons for shaping caste differentiation and social behavior of eusocial insects, such as ants and honeybees. However, the molecular mechanisms governing the sociality of these insects remain obscure. In this study, we profiled the transcriptome and chromatin accessibility of brain tissues in all castes: queens, males, gynes and workers in Monomorium pharaonis which is a typical caste-dependent eusocial insect. We created a comprehensive dataset including 16 RNA-seq and 16 ATAC-seq profiles from 4 biological replicates. We also demonstrated strong reproducibility of the datasets and identified specific genes and open chromatin regions in the genome that may be associated with caste differentiation. Overall, our data will be a valuable resource for further study of the mechanisms underlying eusocial insect behavior, particularly the role of the brain in the control of eusociality.
Project description:The emergence of social organization (eusociality) is a major event in insect evolution. Although previous studies have investigated the mechanisms underlying caste differentiation and social behavior of eusocial insects including ants and honeybees, the molecular circuits governing sociality in these insects remain obscure. In this study, we profiled the transcriptome and chromatin accessibility of brain tissues in three Monomorium pharaonis ant castes: queens (including mature and un-mated queens), males and workers. We provide a comprehensive dataset including 16 RNA-sequencing and 16 assay for transposase accessible chromatin (ATAC)-sequencing profiles. We also demonstrate strong reproducibility of the datasets and have identified specific genes and open chromatin regions in the genome that may be associated with the social function of these castes. Our data will be a valuable resource for further studies of insect behaviour, particularly the role of brain in the control of eusociality.
