Title
(EN) HAPLOID INDUCTION ENHANCER
(FR) STIMULATEUR D'INDUCTION D'HAPLOÏDES
Abstract
(EN)
The present invention relates to methods for haploid induction, based on the HIR8 QTL on maize chromosome 9, as well as associated genes and markers. The invention further relates to identification of haploid inducers, as well as methods for transgenically generating haplotype inducers as well as the combination of haplotype induction and gene editing.
(FR)
La présente invention concerne des procédés d'induction d'haploïdes, basés sur le QTL HIR8 sur le chromosome 9 du maïs, ainsi que des gènes et des marqueurs associés. L'invention concerne en outre l'identification d'inducteurs d'haploïdes, ainsi que des procédés pour générer de manière transgénique des inducteurs d'haplotypes ainsi que la combinaison de l'induction d'haplotypes et de l'édition de gènes.
