Project description:RNAsequening revolutionized the bacterial gene expression analysis. The objective of this study was to identify the genes involved in metabolism of Inulin in Ligilactobacillus agilis. We have obtained a list of genes upregulated in Ligilactobacillus agilis when it is grown in 1% Inulin

Project description:Proteins are ubiquitous macromolecules displaying a vast repertoire of chemical and enzymatic functions making them suitable candidates for chemosignals used in intraspecific communication. Proteins are present in skin gland secretions of vertebrates but their identity, and especially, their functions, remain largely unknown. Many species of lizards possess femoral glands, i.e. epidermal organs primarily involved in the production and secretion of chemosignals playing a pivotal role in mate choice and intrasexual communication. The lipophilic fraction of femoral glands has been well studied in lizards. In contrast, proteins have been the focus of only a handful of investigations. Here, we study the identity, inter-individual expression patterns and functionality of proteins present in femoral glands of sand lizards (Lacerta agilis) by applying mass-spectrometry proteomics. Our results showed that the total number of proteins varied substantially among individuals. None of the identified femoral gland proteins could be directly linked to chemical communication in lizards, although this result hinges on protein annotation in databases in which squamate semiochemicals are poorly represented. In contrast to our expectations, proteins consistently expressed across individuals were related to immune system, antioxidant activity and lipid metabolism as the main functions, adding support to the hypothesis that proteins in reptilian epidermal glands have other functions besides chemical communication. Interestingly, we found that major histocompatibility complex class I (MHC) expression is enriched in femoral gland secretions. Previously, MHC was hypothesized to have been coopted to serve a semiochemical function in sand lizards, specifically in partner recognition. We speculate with the possibility that MHC proteins could be linked to semiochemical function in sand lizards.

Project description:We sought to evaluate the brain gene expression profiles of male courtship display. To assess male display and courtship behavior, we designed a courtship preference assay. We evaluated social interactions between males and females using a 40 gallon tank design with a ‘rock’ habitat at one end and ‘sand’ at the other, separated by glass bottom. When parental rock species (Petrotilapia nigra (TaxId 526958), Maylandia zebra (TaxId 106582), Labeotropheus feulliborni) are placed in this tank paradigm, males court females over the rocks. Males of sand species (Mchenga conophorus, Aulonocara baenschi (TaxId 143496), Tramitichromis intermedius (TaxId 323801)) court females over sand and construct species appropriate bowers. When single rock x sand F1 males were placed in this set up with F1 females, males invariably courted females over the ‘rock’ habitat, suggesting genetic dominance. When two rock x sand F1 males were allowed to compete for F1 females in this tank paradigm, something interesting happened. One male, typically the larger, courted females over the rock habitat, and the other simultaneously constructed bowers to court females in the sand. We detected no difference in GSI (gonadal somatic index) between F1 males behaving as ‘socially rock’ vs. ‘socially sand.’ This observation of divergent behavior among interacting F1 brothers suggests an interaction between the genome and the social environment in these males.

Project description:In this study transcriptomic data of three life history stages of Orciraptor agilis was generated: 1) Gliding cells in absence of food ('gliding'), 2) Cells attached to the cell wall of its algal prey during perforation ('fattacking'), 3) Cells after acquisition of the algal plastid material ('digesting'). Furthermore, RNA-seq of the algal prey Mougeotia sp. was also performed. A de novo transcriptome assembly of the algal reads was performed in order to identify and substract algal reads of the Orciraptor samples by mapping the Orciraptor reads to the algal transcriptome. After this filtering step the remaining Orciraptor reads from all libraries were pooled for a de novo transcriptome assembly of Orciraptor agilis. This transcriptome was the basis for a comparative transcriptomic study in which transcript expression was compared between the three life history stages.

Project description:Lizards cannot naturally regenerate limbs but are the closest known relatives of mammals capable of epimorphic tail regrowth. However, the mechanisms regulating lizard blastema derivation and chondrogenesis remain unclear. We utilized single-cell RNA sequencing analyses of regenerating lizard tails throughout the course of regeneration to assess diversity and heterogeneity in regeneating tail cell populations.
