Project description:The goal of this study was to use heterologous microarray hybridization to determine genomic content shared among different vesicomyid symbionts. These symbionts are closely related and can be thought of as different strains of bacteria, facilitating the use of heterologous microarray hybridization to determine genomic content. Keywords: comparative genomic hybridization

Project description:The goal of this study was to use heterologous microarray hybridization to determine genomic content shared among different vesicomyid symbionts. These symbionts are closely related and can be thought of as different strains of bacteria, facilitating the use of heterologous microarray hybridization to determine genomic content. Keywords: comparative genomic hybridization Microarrays were built off the Ruthia magnifica genome and two replicate hybridizations to this organism were used as a baseline for comparisons. Genomic DNA from two other vesicomyid symbionts (Calyptogena kilmeri and C. pacifica symbionts) was also hybridized to the array with three biological replicates for each sample.

Project description:In many developmental systems, morphogenesis is coupled with dramatic changes in spatiotemporal gene expression, often orchestrated by the coordinated action of transcription factors. Development of the social soil amoebae Dictyostelium discoideum proceeds through a sequence of morphological and transcriptional changes, but the role of transcription factors in development is not well understood. GtaC, a GATA-type zinc-finger transcription factor, is essential for Dictyostelium development. It decodes pulsatile extracellular cAMP signals during early development and mediates cell-type differentiation at later stages. Here, we studied the developmental regulatory roles of GtaC through the concerted analysis of temporal ChIP- and RNA-sequencing data from strains that carry different alleles of gtaC. We show that GtaC exhibits temporally distinctive DNA-binding patterns throughout early development, accompanied by largely cotemporaneous expression of its target genes. We also show that GtaC binds DNA in two modes. One of these modes exhibits binding preferences for canonical GATA-like sequences, the regulatory consequences accompanying which is predominantly up-regulation of target gene expression. The other binding mode is mostly associated with down-regulation. Among its targets we find transcription factors that are essential for development as well as genes involved in cAMP signaling and cell-type specification. Our results suggest that GtaC is a master regulator that regulates multiple physiological processes during early development, when Dictyostelium transitions from a group of unicellular amoebae to an integrated multicellular organism.

Project description:Coral reefs are based on the symbiotic relationship between corals and photosynthetic dinoflagellates of the genus Symbiodinium. We followed gene expression of coral larvae of Acropora palmata and Montastraea faveolata after exposure to Symbiodinium strains that differed in their ability to establish symbioses. We show that the coral host transcriptome remains almost unchanged during infection by competent symbionts, but is massively altered by symbionts that fail to establish symbioses. Our data suggest that successful coral-algal symbioses depend mainly on the symbionts' ability to enter the host in a stealth manner rather than a more active response from the coral host.

Project description:Knockout mutants of polyketide synthase genes were generated (pks1, pks2, pks3, pks14, pks18, pks37) and compared to wild-type AX2 strain of Dictyostelium discoideum using Agilent custom microarrays. The Dictyostelium cells were harvested at eight developmental stages (Amoeboid, Intiation of starvation, loose aggregate, Streaming, Mound, Slug, early culminant, Fruiting body) and subjected to microarray based expression profiling.

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

Project description:Coral reefs worldwide are facing rapid decline due to coral bleaching. However, knowledge of the physiological characteristics and molecular mechanisms of coral symbionts respond to stress is scarce. Here, metagenomic and metaproteomic approach were utilized to shed light on the changes in the composition and functions of coral symbionts during coral bleaching. The results demonstrated that coral bleaching significantly affected the composition of symbionts, with bacterial communities dominating in bleached corals. Difference analysis of gene and protein indicated that symbiont functional disturbances in response to heat stress, resulting in abnormal energy metabolism that could potentially compromise symbiont health and resilience. Furthermore, our findings highlighted the highly diverse microbial communities of coral symbionts, with beneficial bacteria provide critical services to corals in stress responses, while pathogenic bacteria drive coral bleaching. This study provides comprehensive insights into the complex response mechanisms of coral symbionts under thermal stress and offers fundamental data for future monitoring of coral health.
