Повний текст джерелаEverywhere in the world and especially in the intertropical zone, the stored cereals are attacked by numerous insects. The weevils of the Sitophilus genus: Sitophilus granarius, Sitophilus zeamais and Sitophilus oryzae are the most dangerous pests of the cereals. The legume seeds are toxic for these weevils but some strains of Sitophilus oryzae are resistant. We have demonstrated that this resistance is genetically governed by a single autosomal recessive gene. Toxicity was looked for in different pea varieties and in different legume species. It was always present although at very variable levels. Toxicity was limited to the seeds. Classical extraction and purification techniques allowed to establish that the toxic agent was a basic protein of low molecular weight (5,000 Daltons) and was glycosylated. The N terminal sequence showed a high analogy with the lectin site of endochitinases and moreover the protein presents affinity with chitin. The characterization of this protein opens the way towards a new method of protection of the stored cereals implying transgenesis

Повний текст джерелаThis work is an histological and molecular analysis of the intracellular symbiosis that is widespread in the Dryophthoridae family. Phylogenetical study performed on the 16S rDNA gene revealed three endosymbiotics clades belonging to gamma3-Proteobacteria closed to the Enterobacteriaceae. The genus name Candidatus Nardonella was performed for the ancestral clade showing low GC content and infesting Dryophthoridae 100 MY ago. The two other clades show much higher GC content and probably derive of more recent replacement. The pathogenic origin of symbiotic association is supported by the close relation between SOPE (Sitophilus endosymbionts) and Sodalis (glossina endosymbionts) which both conserved genes involved virulence. Comparative genomic by macroarray allows the study of intracellular evolution of genomes submitted to different selective pressure

Повний текст джерелаThree gorse species co-exist in Brittany (France), all of them being parasitised by seed-eating weevils. One of them, Ulex europaeus is an invasive plant. I contributed to a long-term study of Ulex europaeus. We have shown that the parasite pressure has a major impact for the plant, which can explain the areas invaded; where specific grazers are absent, it can have an increased competitive advantage. I have enlarged this study to two other gorse species that occur in Brittany: U. Gallii and U. Minor. These species flower in the autumn, and are also parasitised by weevils. I have identified these weevils by using morphological and molecular characters as Exapion lemovicinum. The life cycles and the cold hardiness of these weevils are intimately linked to the phenology of their host plant. The ecological specialisation of the weevils is therefore probably the origin of their differentiation, which could have taken place by temporal isolation by means of a process of sympatric speciation

Повний текст джерелаAmong biodiversity theories, the niche theory states that competing species can durably coexist whenever they exhibit differences in their traits leading to partitioning of their ecological niches. Moreover, housing symbiotic bacteria is now recognized as expanding the host phenotype and is thus likely to interfere with its ecological niche. Intriguingly, the question of whether endosymbionts are likely to shape communities of competing insect species has not yet been addressed in natural systems. My hypothesis is that endosymbiosis can be determinant in driving the dynamics of communities composed of competing host species by amplifying differences in theirs traits and thus, stabilizing their coexistence. Reciprocally, ecological interactions among these host species could have a decisive role in the evolutionary dynamic of endosymbiotic cortege of each species by providing opportunities of horizontal transfer of bacterial endosymbionts. During my PhD, I studied endosymbiotic relationships among communities consisting of four species of specialist oak weevil insects (Curculio spp., Coleoptera, Curculionidae) that are competing for egg-laying into acorns where the larva grow. The two main objectives of my thesis were (i) to describe and compare the endosymbiotic corteges housed by the four species, by means of molecular screening of the bacterial diversity in female ovaries and measuring their prevalence in males and females of host populations, and (ii) to check the existence horizontal transfers of endosymbionts between host species with a multigenic approach combined to estimating the probability for one acorn to be infested by larva belonging to distinct Curculio species. I found that the four weevil species overall harboured distinct endosymbiotic communities, and notably that three of the four species had their own major secondary symbiont. Additionally, I found that the four species had a clearly distinct period of larval development during the reproductive season. Such diversification of endosymbionts across species competing with each other might contribute to their temporal partitioning in the acorn use. Otherwise, the fact that each host species also hosts, with residual prevalence, most of endosymbionts found in the other species, argues for the existence of horizontal transfer among this community. This hypothesis seems to be confirmed by a fine-tuned comparison of the Wolbachia strains detected in these host communities and by the non negligible proportion of acorns which are simultaneously infested by two or more weevil species. These results support the hypothesis of an impact of endosymbiotic communities on the dynamics of competing host communities and point out the need to consider the host community scale in order to understand the dynamics of bacterial communities within host species populations

Повний текст джерела[Sitophilus oryzae harbours symbiotic bacteria in the ovaries and in a specialized larval organ : the bacteriorne. They are transmitted to the progeny only through. The oocyte, and their role in the physiology of the host has been made possible by the obtention of aposymbiotic strains. For aposymbiotic insects the development rime is lengthened and the fertility reduced. A physiological study showed that the symbiotes provide their host with five vitamins. The comparison of six enzymatic activities in mitochondria symbiotic (SS) and aposymbiotic (AA) weevils shows diminished values in the AA ones. As they have been reared in the laboratory since 1974, we could not exclude the possibility that genetic drift has occurred between AA and SS insects. So we carried out a study of the enzymatic activities of mitochondrial pellets from reciprocal hybrid insects. The results confirmed that the differences in the mitochondrial enzymatic activities are due to the presence of symbiotic bacteria in SS strain. In another way, the mitochondrial genomes of the two strains express the same number of polypeptides when the mitochondria are incubated in vitro. . Finally, we tested the nutritional effect, by comparing the enzymatic activities of mitochondria isolated from AA and SS strains, reared on wheat flour complemented or no with vitamins. In these conditions, the enzymatic activities of the two strains are increased, but the differences between the two strains are diminished while being still significant (except for pyruvate deshydrogenase). So we conclude that bacteria could interfere in vivo with mitochondrial activities be providing vitamins to the host (pantothenic acid and riboflavin). ]

Повний текст джерелаMany insect species require for their reproduction and development the presence of symbiotic intracellular bacteria that are localized in a specialized organ called the bacteriome. Yet, little is known about the host-symbiont interaction with regard to immunity. To tackle this aspect, we have identified immune-relevant genes from the weevil Sitophilus zeamais and we have quantified their expression level in the bacteriome. We have revealed the overexpression of one antibacterial peptide (coleoptericin) and two negative regulators of the immune response (Tollip, PGRP) in the symbiotic organ. Furthermore, we have shown that the weevil PGRP gene is alternatively spliced: one isoform is spliced after infection of the larvae by Escherichia coli while the other is mainly spliced in the bacteriome. Taken together, these data show the existence of a moderate host immune response in the bacteriocyte and suggest that the molecular regulation of the immune system is adapted to intracellular bacterial maintenance and growth in the symbiont-bearing organ of insects
