Le système de reproduction d'un organisme a un impact sur l'émergence et l'évolution de nouveaux génotypes. La compréhension du mode de reproduction chez les organismes pathogènes aide à comprendre leur histoire de vie. Les mécanismes biologiques, et les gènes sous-jacents, impliqués dans la reproduction sexuée chez les Ascomycètes sont relativemen...

Plant-associated fungi have an important role in our ecosystems, either through beneficial, neutral or harmful interactions. In particular, phytopathogenic fungi represent a threat to global food security. Rapeseed (Brassica napus), the world’s second-largest oilseed crop, is mainly threatened by the ascomycete Leptosphaeria maculans. The latter di...

In dinoflagellates, sexual reproduction is best known to be induced by adverse environmental conditions and culminate in encystment for survival ('sex for encystment'). Although increasing laboratory observations indicate that sex can lead to production of vegetative cells bypassing encystment, the occurrence of this alternative pathway in natural ...

Morels are highly prized edible fungi where sexual reproduction is essential for fruiting-body production. As a result, a comprehensive understanding of their sexual reproduction is of great interest. Central to this is the identification of the reproductive strategies used by morels. Sexual reproduction in fungi is controlled by mating-type ( MAT ...

My thesis focuses on the asymptotic analysis of integro-differential models quantifying the influence of certain features of sexual reproduction on the eco-evolutionary dynamics of spatially distributed species characterized by quantitative traits with complex genetic architecture. It extends the analytical toolkit to study the dynamics of singular...

The unicellular green alga Chlamydomonas reinhardtii (hereafter Chlamydomonas) possesses both plant and animal attributes, and it is an ideal model organism for studies of fundamental processes such as photosynthesis, sexual reproduction, and the life cycle. N6-methyladenosine (m6A) is the most prevalent mRNA modification, and it plays important ro...

Austropuccinia psidii is the causal agent of myrtle rust, a fungal disease that infects over 480 species in the Myrtaceae. A. psidii is a biotrophic pathogen that reproduces sexually and asexually. Sexual reproduction has been previously shown on Syzygium jambos and little is known about its reproductive biology on other hosts or whether population...

1-aminocyclopropane 1-carboxylic acid (ACC) is the immediate precursor of the plant hormone ethylene. However, recent studies have suggested that ACC also acts as a signaling molecule to regulate development and growth independently from ethylene biosynthesis. In red algae, ACC stimulates the switch from a vegetative to a sexual reproductive phase....

Le stress de sevrage provoque un dysfonctionnement de la barrière intestinale en libérant le facteur de libération de la corticotrophine (CRF) et en induisant la dégranulation des mastocytes intestinaux, ce qui compromet le bien-être du porcelet (Moeser et al., 2007). L’objectif de cette étude était d’évaluer comment le stress social, un autre fact...

Après avoir défini une méthode d’évaluation de la prise colostrale (PC), Leneveu et al. (2019) ont identifié des facteurs pouvant l’influencer. Parmi eux la pratique des tétées alternées (TA), qui consiste à bloquer des porcelets sous une lampe chauffante pour favoriser l’accès à la mamelle des petits porcelets et leur PC, n’a jamais été évaluée.
