Project description:We sequenced total RNA from Dirofilaria immitis in order to generate the first tissue-specific gene expression profile of a filarial nematode and its Wolbachia endosymbiont.
Project description:We sequenced total RNA from Dirofilaria immitis in order to generate the first tissue-specific gene expression profile of a filarial nematode and its Wolbachia endosymbiont. Examination of transcript levels in 7 different Dirofilaria immitis tissues, in duplicate, using Illumina GAIIx.
Project description:As an endosymbiont, Wolbachia exerts significant effects on the host, including on reproduction, immunity, and metabolism. However, the study of Wolbachia in Thysanopteran insects, such as flower thrips Frankliniella intonsa, remains limited. Here, we assembled a gap-free looped genome assembly of Wolbachia strain wFI in a length of 1,463,884 bp (GC content 33.80%), using Nanopore long reads and Illumina short reads. The annotation of wFI identified a total of 1838 protein-coding genes (including 85 pseudogenes), 3 ribosomal RNAs (rRNAs), 35 transfer RNAs (tRNAs), and 1 transfer-messenger RNA (tmRNA). Beyond this basic description, we identified mobile genetic elements, such as prophage and insertion sequences (ISs), which make up 17% of the entire wFI genome, as well as genes involved in riboflavin and biotin synthesis and metabolism. This research lays the foundation for understanding the nutritional mutualism between Wolbachia and flower thrips. It also serves as a valuable resource for future studies delving into the intricate interactions between Wolbachia and its host.
Project description:The antennal transcriptome analysis was performed for F. occidentalis and F. intonsa, and the putative chemosensory genes (OBPs and CSPs) were identified and compared between the two species
