La recombinaison méiotique initiée en prophase I de méiose génère soit des crossing-over (COs), qui sont des échanges réciproques entre segments chromosomiques, ou des conversions géniques non associées aux COs (NCOs). Les deux types d'événements se produisent dans de petites régions (moins de 10 kilobases) appelées points chauds, qui sont distribuées de manière non homogène le long des chromosomes. L'objectif de ma thèse était la caractérisation d'un point chaud de recombinaison méiotique (nommée 14a) chez Arabidopsis thaliana (i) dans différentes accessions (ii) dans le mutant msh4, un gène impliqué dans la formation des COs. Dans les deux hybrides ColxLer et ColxWs (i) 14a a un taux très élevé de COs 0,85% et 0,49%, respectivement (ii) L...
