SAMENVATTING
The production of true-breeding lines through doubled-haploid production is an important tool in crop breeding, but one that is limited by the inherent recalcitrance of different species and genotypes for this process. The project will use a three-pronged approach to understand and induce doubled-haploid production from female reproductive organs (gynogenesis) in tomato:
- We will examine the involvement of major plant hormones in driving the transition from the egg cell to the fertilized zygote.
- Chemical screens will be performed to identify small molecule enhancers of gynogenesis
- We will ectopically express embryo-identity transcription factors in the egg cell to induce gynogenesis.
The project aims to use knowledge from sexual embryo initiation and the processes affected by gynogenesis-inducing compounds as a framework to identify global pathways that underlie gynogenesis in plants. This knowledge, together with the specific compounds and proteins identified in the screens, will provide a solid starting point to develop efficient germplasmindependent protocols for DH production via gynogenesis in tomato.
