Project description:Using a tiled whole-genome microarray, we found that 58.2% of Tribolium castaneum genes are maternally loaded into eggs. Comparison of known Drosophila melanogaster maternal genes to our results showed widespread conservation of maternal function with T. castaneum. We also found many T. castaneum genes with previously identified gender or tissue specific expression were also maternally loaded into eggs. The microarray design also allowed the detection of 2315 and 4060 novel transcriptionally active regions greater in length than 100 bp in unfertilized and fertilized T. castaneum eggs, respectively. The primary objective of this study was to identify expressed regions of the Tribolium castaneum genome in unfertilized and fertilized eggs using a whole-genome tiled microarray.

The whole RNA of 3 samples of virgin laid eggs and 3 samples of fertilized eggs were compaired.

Project description:We report Illumina-generated RNASeq data of several populations of Tribolium castaneum larvae selected for higher or lower immune priming specificity as well as unselected control populations. From each of these populations, we injected groups of 20 larvae with either one of three bacteria species or left them untreated as controls. Whole body samples were taken 6h after injection and used for RNASeq Analysis.
Project description:The presence of DNA methylation in beetles (Coleoptera) has only been investigated with bisulfite sequencing of Tribolium castaneum, which produced no evidence of DNA methylation. Here, we used whole genome bisulfite sequencing to assay if DNA methylation was present in another beetle, Nicrophorus vespilloides. We used T. castaneum as a negative control.
