Project description:Previously, transcriptomics data for mollusc has been obtained by whole-brain bulk RNA-seq and low-throughput scRNA-seq. We want to construct the first molluscan high-throughput single-neuron transcriptomes for Berghia stephanieae. Around 129,000 cells were collected from 20 brains and the libraries were constructed using the 10X Genomics' Chromium platform. The brains were separated into two samples: the main brain (i.e., the cerebropleural, pedal, buccal ganglion) and the rhinophore ganglion sample. After library preparation, around 1,000 cells were receovered and sequenced. After data analysis, the cells formed eight clusters with marker genes for each cluster identified. Various cell populations that express a wide range of both small-molecule neurotransmitters and neuropeptides such as serotonergic, small cardioactive peptide (SCP), APGWamide, and FMRFamide cells were also identified in the dataset. Interestingly, cells from the rhinophore ganglion of Berghia exhibit great cell heterogeneity, with cells splitting into two general categories and four distinct clusters. The project produced a single-cell dissociation protocol that can be adapted for use in other nudibranch molluscs and a custom data analysis pipeline for data of this nature.

Project description:Green hydra (Hydra viridissima) harbors endosymbiotic Chlorella and have established a mutual relation. To identify the host hydra genes involved in the specific symbiotic relationship, transcriptomes of intact H. viridissima colonized with symbiotic Chlorella strain A99, aposymbiotic H.viridissima and H. viridissima artificially infected with other symbiotic Chlorella were compared by microarray analysis. The results indicated that genes involved in nutrition supply to Chlorella were upregulated in the symbiotic hydra. In addition, it was induced by supply of photosynthates from the symbiont to the host, suggesting cooperative metabolic interaction between the host and the symbiotic algae.

Project description:Colonization of deep-sea hydrothermal vents by invertebrates was made efficient through their adaptation to a symbiotic lifestyle with chemosynthetic bacteria, the primary producers of these ecosystems. Anatomical adaptations such as the establishment of specialized cells or organs have been evidenced in numerous deep-sea invertebrates. However, very few studies detailed global inter-dependencies between host and symbionts in these ecosystems. In this study, we proposed to describe, using a proteo-transcriptomic approach, the effects of symbionts on the deep-sea mussel Bathymodiolus azoricus’ molecular biology. We induced an in situ depletion of symbionts and compared the proteo-transcriptome of the gills of mussels in three conditions: symbiotic mussels (natural population), symbiont-depleted mussels and aposymbiotic mussels
