In canaries, specific phrases of male song (sexy songs, SS) that are difficult to produce are especially attractive for females. Females exposed to SS produce more copulation displays and deposit more testosterone into their eggs than females exposed to non-sexy songs (NS). Increased expression of the immediate early genes c-Fos or zenk (a.k.a. egr-1) has been observed in the auditory forebrain of female songbirds hearing attractive songs. C-Fos immunoreactive (Fos-ir) cell numbers were quantified here in the brain of female canaries that had been collected 30min after they had been exposed for 60min to the playback of SS or NS or control white noise. Fos-ir cell numbers increased in the caudomedial mesopallium (CMM) and caudomedial nidopallium (NCM) of SS birds as compared to controls. Song playback (pooled SS and NS) also tended to increase average Fos-ir cell numbers in the mediobasal hypothalamus (MBH) but this effect did not reach full statistical significance. At the individual level, Fos expression in CMM was correlated with its expression in NCM and in MBH but also with the frequency of calls that females produced in response to the playbacks. These data thus indicate that male songs of different qualities induce a differential metabolic activation of NCM and CMM. The correlation between activation of auditory regions and of the MBH might reflect the link between auditory stimulation and changes in behavior and reproductive physiology. [less ▲]

BACKGROUND: The origin of functional innovation is among the key questions in biology. Recently, it has been shown that new genes could arise from non-coding DNA and that such novel genes are often involved in male reproduction. RESULTS: With the aim of identifying novel genes, we used the technique "generation of longer cDNA fragments from serial analysis of gene expression (SAGE) tags for gene identification (GLGI)" to extend 84 sex-biased 3'end SAGE tags that previously could not be mapped to the D. pseudoobscura transcriptome. Eleven male-biased and 33 female-biased GLGI fragments were obtained, of which 5 male-biased and 3 female-biased tags corresponded to putatively novel genes. This excess of novel genes with a male-biased gene expression pattern is consistent with previous results, which found novel genes to be primarily expressed in male reproductive tissues. 5' RACE analysis indicated that these novel transcripts are very short in length and could contain introns. Interspecies comparisons revealed that most novel transcripts show evidence for purifying selection. CONCLUSION: Overall, our data indicate that among sex-biased genes a considerable number of novel genes (approximately 2-4%) exist in D. pseudoobscura, which could not be predicted based on D. melanogaster gene models.

Le logciel Cassandre fait partie de la plateforme Hypertopic d'annotation collaborative de textes et d'images. Du point de vue de la recherche en informatique, le développement de cette plateforme s'insère dans le courant du Web socio-sémantique. Du point de vue des sciences humaines, la plateforme fournit des outils de recherche qualitative. Christophe Lejeune fait le récit de son expérience de développement (de 2005 à aujourd'hui). Ce faisant, il illustre des notions abordées dans les séances précédentes, telles que les questions de gestionnaire de versions, les services Web RESTful, les centres de calcul, les nuages, les collaborations inter-universitaires, les communautés Open Source et la relation avec les utilisateurs.

Dans les modèles télégraphiques,on considère que la communication fonctionne si les messages de départ et d’arrivée sont identiques.Sinon, cela signifie que le récepteur a mal compris ou que l’émetteur s’est mal fait comprendre. Dans ce cadre, la pathologie de la communication est l’incompréhension. Ce que nous proposons ici, à partir de l’analyse de situations de communication très particulières (des rencontres enchantées avec des dauphins sauvages), c’est que, à l’inverse, la structure fondamentale de la communication est le malentendu. Or, c’est le refus de reconnaître ce fait (dû notamment au désir vain et désastreux de contrôler le partenaire) qui engendre des pathologies.Admettre au contraire qu’émetteur et récepteur disposent nécessairement de versions différentes de l’interaction et qu’il n’y a pas de version plus objective qu’une autre, c’est replacer l’altérité au coeur d’une communication qui est réussie parce qu’on accepte de mal se comprendre.
