'Sunkha' palms are endemic to Bolivia, where they occupy an extremely limited range and face several threats. Picture taken during a field trip in 2019 to visit wild stands of the palm. Part of Nicol�s' research focuses on the conservation genomics of Parajubaea palms in Bolivia.

Offre de maitrise en biologie végétale

Approches moléculaires pour la caractérisation des banques de graines de mauvaises herbes

Contexte

La caractérisation des banques de graines de mauvaises herbes dans les sols agricoles, est un outil de choix pour élaborer ou ajuster les programmes de phytoprotection avant que ces mauvaises herbes ne prolifèrent. À l’heure actuelle, cette caractérisation s’effectue principalement soit par la méthode d’émergence des plantules, soit par la méthode par microscopie. Ces deux méthodes exigent toutefois beaucoup de temps, demandent une expertise pointue, ou possèdent différents biais méthodologiques. Le développement des outils moléculaires pourrait permettre de concevoir de nouvelles méthodes, rapides et fiables, pour caractériser les banques de graines. Ce projet vise à évaluer la performance des outils moléculaires pour caractériser les banques de graines de mauvaises herbes.

Objectifs

Effectuer des caractérisations de banques de graines à l’aide de la méthode d’émergence des plantules et de la méthode par microscopie,
Collaborer aux analyses de séquençage à haut débit,
Comparer les résultats obtenus à l’aide des trois méthodes à l’étude.

Profil recherché

Baccalauréat en agronomie, en biologie, ou en microbiologie
Intérêt pour la malherbologie et les productions végétales
Goût pour le travail expérimental
Connaissances en analyses statistiques à l’aide du logiciel R
Première expérience en recherche scientifique (atout)

Le projet débutera en septembre 2024 pour une durée de deux ans et inclut un soutien financier de 18 000$/an. Le projet sera supervisé par Bérenger Bourgeois, professeur adjoint au Département de phytologie de l’Université Laval, co-supervisé par Élise Smedbol, chercheure à l’Institut de recherche et de développement en agroenvironnement (IRDA), et mené en étroite collaboration avec le Laboratoire d’expertise et de diagnostic en phytoprotection du MAPAQ.

Pour déposer votre candidature, veuillez faire parvenir une lettre de motivation, un CV et une copie de vos relevés de notes universitaires accompagnés des coordonnées de trois références avant le 1er juillet 2024 à Bérenger Bourgeois à l’adresse berenger.bourgeois.1@ulaval.ca
