Species determination of freshwater snails is particularly important in the case of disease vectors. In central France, for example, it has been shown that Galba truncatula (Müller, 1774) and Omphiscola glabra (Müller, 1774), which can be found in sympatry, are intermediate hosts for fasciolosis. Although these two species are distinguishable based on their shell morphology, some snails present...

INTRODUCTION In sexually reproducing organisms, gametes are generated by a specific lineage derived from somatic cells that undergo a somaticto-reproductive cell fate transition (SRT). In mammals, the primordial germ cells (PGCs) differentiate in the embryo at gastrulation stage (Bendel-Stenzel et al., 1998). By contrast, the spore mother cells (SMCs) of flowering plants are formed in the adult...

Malaria control strategies aiming at reducing disease transmission intensity may impact both oocyst intensity and infection prevalence in the mosquito vector. Thus far, mathematical models failed to identify a clear relationship between Plasmodium gametocytes and their infectiousness to mosquitoes. Natural isolates of gametocytes are genetically diverse and biologically complex. Infectiousness ...

C. Franche1,*, D. Diouf1, Q.V. Le1, D. Bogusz1, A. This capacity for rapid growth comes from a symbiotic association with an actinomycete of the genus Frankia, N’Diaye1, H. Gherbi1, C. Gobé1 and E. Duhoux1,2 1Physiologie Cellulaire et Moléculaire des Arbres which allows A. verticillata to fix dinitrogen in root nodules, so-called actinorhizae (Benson and Silvester, 1993).

As all other human activities, horticulture is accountable for its impact on the resources available, now and in the future, to our societies. The problem is of particular importance in production systems that are often intensive and require high amounts of inputs. To fit with the increasing number of regulations and contracts growers have to respect, tools must be created to evaluate existing ...
