Project description:Small octopus is one of the major source for V. vulnificus outbreak among aquatic products in Northeast Asian due to improperly cooking and wound infection by mishandling. However, there is no report on whole genome sequence of V. vulnificus isolated from contaminated surf clam, thus no information is available for major virulence factors about V. vulnificus obtained from small octopus. Therefore, the analysis of transcriptome of isolated V. vulnificus from products are necessary to investigate potential risk of foodborne illness by contaminated products.

Project description:Octopuses are mollusks that evolved intricate neural systems which are comparable with vertebrates in terms of cell number, complexity and size. Exactly how an octopus increases its neural cell number so dramatically and whether an increase in cell type diversity enables higher cognitive function and complex behavior is still unknown. To profile the cell diversity of the developing octopus brain we applied 10x Genomics’ single-cell/nuclei RNA sequencing technology. At hatching, the Octopus vulgaris brain possesses the main lobes and connections of an adult brain, but which cell types are present remains elusive. We were able to identify 42 robust cell types comprising mostly neural cells, as well as multiple glial subtypes and other non-neuronal populations such as endothelial cells and fibroblasts. In situ expression analysis of marker genes allowed spatial mapping of clusters, including vertical lobe cells and several optic lobe cell types. Investigation of cell type conservation indicated similar gene expression signatures between glial cells of mice, fly and octopus. Genes related to memory and learning were found enriched in vertical lobe cells, that showed molecular similarities with Kenyon cells in Drosophila but not to any mouse cell type. Lastly, we also analyzed the expression of newly expanded gene families (protocadherins, C2H2 zinc-finger transcription factors and G-protein coupled receptors) and found that these are enriched in specific cell types. Taken together, our data gives insight into cell type evolution and the composition of the complex octopus brain.

Project description:Three adult individuals of the Octopus vulgaris were collected from the Southern Tyrrhenian Sea (Italy). For each animal, total RNA was isolated from the supra- (SEM), sub- (SUB) esophageal masses, optic lobes (OL) and the arms (ARM). The RNA-sequencing has been performed using Illumina technology.

Project description:Cephalopods have a remarkable visual system, with a camera-type eye, high acuity vision, and a wide range of sophisticated visual behaviors. However, the cephalopod brain is organized dramatically differently from that of vertebrates, as well as other invertebrates, and little is known regarding the cell types and molecular determinants of their visual system organization beyond neuroanatomical descriptions. Here we present a comprehensive single-cell molecular atlas of the octopus optic lobe, which is the primary visual processing structure in the cephalopod brain. We combined single-cell RNA sequencing with RNA fluorescence in situ hybridization to both identify putative molecular cell types and determine their anatomical and spatial organization within the optic lobe. Our results reveal six major neuronal cell classes identified by neurotransmitter/neuropeptide usage, in addition to non-neuronal and immature neuronal populations. Moreover, we find that additional markers divide these neuronal classes into subtypes with distinct anatomical localizations, revealing cell type diversity and a detailed laminar organization within the optic lobe. We also delineate the immature neurons within this continuously growing tissue into subtypes defined by evolutionarily conserved fate specification genes as well as novel cephalopod- and octopus- specific genes. Together, these findings outline the organizational logic of the octopus visual system, based on functional determinants, laminar identity, and developmental markers/pathways. The resulting atlas presented here delineates the “parts list” of the neural circuits used for vision in octopus, providing a platform for investigations into the development and function of the octopus visual system as well as the evolution of visual processing.
