The expansion of multi-omics datasets raises significant challenges for data integration and querying. To overcome these challenges, we developed a generic RDF-based integration schema that connects various types of differential -omics data, epigenomics, and regulatory information. This schema employs the FALDO ontology to enable querying based on genomic locations.

Article Synopsis
  • The first nuclear genome assembly and complete mitochondrial genome (mitogenome) for Hylesia metabus, a species of moth, has been presented, with the nuclear genome being one of the largest for lepidopterans at 1,271 Mb.
  • The nuclear genome is organized into 31 pseudo chromosomes with a high quality BUSCO score of 99.5%, and contains a significant amount of repetitive elements, primarily located in intergenic regions.
  • The assembled genomes are available on the BIPAA website and will aid future studies in population and comparative genomics.

In order to capture the drought impacts on seed quality acquisition in Brassica napus and its potential interaction with early biotic stress, seeds of the 'Express' genotype of oilseed rape were characterized from late embryogenesis to full maturity from plants submitted to reduced watering (WS) with or without pre-occurring inoculation by the telluric pathogen Plasmodiophora brassicae (Pb + WS or Pb, respectively), and compared to control conditions (C). Drought as a single constraint led to significantly lower accumulation of lipids, higher protein content and reduced longevity of the WS-treated seeds. In contrast, when water shortage was preceded by clubroot infection, these phenotypic differences were completely abolished despite the upregulation of the drought sensor RD20.

Article Synopsis
  • Thousands of endoparasitoid wasp species from the Braconidae and Ichneumonidae families carry domesticated endogenous viruses (DEVs), specifically ichnoviruses (IVs), in their genomes.
  • The study focuses on how large quantities of IV virions are produced in the ovary calyx cells of female wasps, especially during pupal and adult stages, and how these virions aid in the successful development of wasp offspring by infecting host insects.
  • Researchers generated a detailed genome assembly for the Hyposoter didymator wasp and identified 67 HdIV loci, concluding that a specific gene, U16, is crucial for both the amplification of these loci and the formation of vir
